So do not bet against bubbles, because they can get bigger and bigger, totally irrational eventually, like a rubber band that gets stretched too far, it snaps back, and all those fake gains that weren’t fundamentally based get erased and investors get wiped out.”Larry Swedroe In this episode of Enrich Your Future, Andrew and Larry Swedroe discuss Larry’s new book, Enrich Your Future: The Keys to Successful Investing.

Today, Andrew and Larry discuss Chapter 36: Fashions and Investment Folly.Chapter 36: Fashions and Investment FollyIn this chapter, Larry explains why investors allow themselves to be influenced by the herd mentality or the madness of crowds.Perfectly rational people can be influenced by a herd mentalityWhen it comes to investing, otherwise perfectly rational people can be influenced by a herd mentality. The potential for significant financial rewards plays on the human emotions of greed and envy. In investing, as in fashion, fluctuations in attitudes often spread widely without any apparent logic.Larry notes that one of the most remarkable statistics about the world of investing is that there are many more mutual funds than stocks, and there are also more hedge fund managers than stocks. There are also thousands of separate account managers. The question is: Why are there so many managers and so many funds?Effects of recency biasAccording to Larry, there are several explanations for the high number of managers and funds. The first is the all-too-human tendency to fall subject to “recency.” This is the tendency to give too much weight to recent experience while ignoring the lessons of long-term historical evidence. Larry says that investors subject to recency bias make the mistake of extrapolating the most recent past into the future, almost as if it is preordained that the recent trend will continue.The result is that whenever a hot sector emerges, investors rush to jump on the bandwagon, and money flows into that sector. Inevitably, the fad (fashion) passes and ends badly. The bubble inevitably bursts.Investment ads create demand where there is noneAnother reason, Larry notes, is that the advertising machines of Wall Street’s investment firms are great at developing products to meet demand. The record indicates they are even great at creating demand where none should exist.The internet became the greatest craze of all, and internet funds were designed to exploit the demand. Investors lost more fortunes

In this episode of Enrich Your Future, Andrew and Larry Swedroe discuss Larry’s new book, Enrich Your Future: The Keys to Successful Investing. In this series, they discuss Chapter 35: Mad Money.LEARNING: Investors are naive, and Cramer is an entertainer, not a financial advisor who adds value. “Do not confuse information with value-added information.

Today, Andrew and Larry discuss Chapter 35: Mad Money.Chapter 35: Mad MoneyIn this chapter, Larry explains why investment advice from so-called market experts is often worthless.The infamous Jim CramerJim Cramer, a former hedge fund manager, has become one of the most recognizable faces in the investment world. He dispenses rapid-fire investment advice on the show “Mad Money.” Since it premiered in March 2005, it has been one of CNBC’s most-watched shows. But has his advice been as successful for the investors who follow it? Larry shares a couple of research studies that answer this question.It pays more to invest in an S&P than in Cramer’s fundCramer manages a portfolio that invests in many of the stock recommendations he makes on TV. Established in August 2001 with approximately $3 million, the Action Alerts PLUS (AAP) portfolio has been the centerpiece of Cramer’s media company, TheStreet, which sells his financial advice, giving subscribers in the millions access to each trade the portfolio makes ahead of time. Jonathan Hartley and Matthew Olson, authors of the 2018 study “Jim Cramer’s Mad Money Charitable Trust Performance and Factor Attribution,” examined the AAP portfolio’s historical performance. Their study covered the period from August 1, 2001, the AAP portfolio’s inception, through December 31, 2017. The study found that the fund returned a total of 97%. During that same period, an investment in the S&P would have returned 204%.No real stock-picking skill, just entertainmentIn another study, “How Mad Is Mad Money?”, Paul Bolster, Emery Trahan, and Anand Venkateswaran examined Cramer’s buy and sell recommendations for the period from July 28, 2005, through December 31, 2008. They also constructed a portfolio of his recommendations and compared it to a market index. The researchers came to three key conclusions:Investors were paying attention, as the stocks he recommended had abnormal returns of almost 2% on the day following his recommendations.The returns...

He helps build powerful personal brands in just one week and pioneers Generative AI for executives, speaking at elite events like Abundance 360, MIT, and Tony Robbins’ gatherings.Worst investment everMike learned about a SaaS startup from a client with whom he had spent time and had gotten to know, like, and trust him. So, when the client introduced Mike to this deal, he got interested.The startup looked great, so he invested a substantial amount of money and then doubled down because it got even better.Off to a promising startThe basic premise was that it was a pool. The founders would find SaaS companies with customers, momentum, technology, and a bit of a moat. They had much experience and success, such as a 10x dividend to investors in three years.Infighting paralyzes everythingUnfortunately, the two founders started fighting. One of them locked the other one out of everything. They had the majority and equal shareholding, making infighting even worse. The remaining partner started emptying the coffers.Someone doing the books became a whistleblower and revealed the shenanigans going on. The partner was siphoning off money, building a house, going on big trips, using private jets everywhere, etc. It got uglier and uglier, causing the shareholders to file lawsuits, and the FTC got involved. Years have gone by, and things are still shut down.Lessons learnedTime kills deals.Character is bigger than charisma. Crooked founders will gut you faster than any market downturn.Put all that money into index funds and let it compound.Andrew’s takeawaysThe only way to invest as an angel investor is to invest in 10 startups. Don’t do it if you are not prepared with the money and time to do that.Actionable adviceUnless you’re a full-time VC with deal flow, customer channels, or an exit mapped out, keep your money in things you can control. If you’re a shareholder, your best exit is for a big company to come and buy what they believe is money at a discount.Mike’s recommendationsMike recommends learning to build a brand that will elevate everything you touch for the rest of your life. He suggests reading his book, Your Next Act: The Six Growth Accelerators for Creating a Business You’ll Love for the Rest of Your Life, to help you build your brand. He also recommends immersing yourself in AI and learning how to use it effectively.No.1 goal for the next 12 monthsMike’s number one goal for the next 12 months is to become an international citizen. He wants to continue living his beautiful life in multiple locations and working with more entrepreneurs worldwide.Parting words&nbsp;“Go out and build your brand.

You can learn more about Larry’s Worst Investment Ever story on Ep645: Beware of Idiosyncratic Risks.Larry deeply understands the world of academic research and investing, especially risk. Today, Andrew and Larry discuss Chapter 34: Bear Markets: A Necessary Evil.Chapter 34: Bear Markets: A Necessary EvilIn this chapter, Larry explains why investors must view bear markets as necessary evils. He says that if stocks didn’t experience the kind of bear markets that we have, investors would be very unhappy.Larry further explains that the most basic finance principle is the relationship between risk and expected, but not guaranteed, return. So, the higher the risk, the higher the expected return, which means that if the risk is high, investors will apply a bigger risk premium, which will lead to the denominator in the formula of the Net Present Value. The numerator is the expected earnings. The denominator is the risk-free rate plus the risk premium.The higher the risk, the higher the premiumsLarry highlights historical bear markets, noting the U.S. has experienced losses exceeding 34% during the COVID crisis and 51% from 2007 to 2009. He argues that these losses are essential for investors to demand higher risk premiums. The very fact that investors have experienced such significant losses leads them to price stocks with a large risk premium.From 1926 through 2022, the S&amp;P provided an annual risk premium over one-month Treasury bills of 8.2% and an annualized premium of 6.9%. If the losses that investors experienced had been smaller, the risk premium would also have been smaller. And the smaller the losses experienced, the smaller the premium would have been.In other words, the less risk investors perceive, the higher the price they are willing to pay for stocks. And the higher the market’s price-to-earnings ratio, the lower the future returns.Staying the course during underperformanceThe bottom line, Larry says, is that bear markets are necessary for the creation of the large equity risk premium we have experienced. Thus, if investors want stocks to provide high expected returns, bear markets (while painful to endure) should be considered a necessary evil.However, Larry notes that it is during the periods of underperformance that investor discipline is tested. Unfortunately, the evidence suggests that most investors significantly underperform the stock market and the mutual funds they invest in. The underperformance is because investors act like generals fighting the last war.Subject to <a...

Don’t try to pick individual stocks or time the market, just invest in a disciplined way, and you will win by getting the market’s return.”Larry Swedroe&nbsp;In this episode of Enrich Your Future, Andrew and Larry Swedroe discuss Larry’s new book, Enrich Your Future: The Keys to Successful Investing.

Today, Andrew and Larry discuss Chapter 33: An Investor’s Worst Enemy.Chapter 33: An Investor’s Worst EnemyIn this chapter, Larry demonstrates why investors are their own worst enemies. He observes that many people think the key to investing is identifying the stocks that will outperform the market and avoiding the ones that will underperform.Yet the vast body of evidence says that’s playing the losers’ game. He adds that most professionals with advanced degrees in finance and mathematics, with access to the best databases and huge advantages over individuals, often think they’re smart enough to beat the market.They do so by attempting to uncover individual securities they believe the rest of the market has somehow mispriced (the price is too high or too low). They also try to time their investment decisions to buy when the market is “undervalued” and sell when it is “overvalued.”However, evidence shows that 98% of them fail to outperform in any statistically significant way on a risk-adjusted basis, even before taxes. As historian and author Peter Bernstein puts it: “The essence of investment theory is that being smart is not a sufficient condition for being rich.”Why do people keep playing the loser’s game?In the face of such overwhelming evidence, the puzzling question is why people keep trying to play a game they are likely to lose. From Larry’s perspective, there are four explanations:Because our education system has failed investors and Wall Street, and most financial media want to conceal the evidence, people are unaware of it.While the evidence suggests that playing the game of active management is the triumph of hope over wisdom and experience, hope does spring eternal—after all, a small minority succeed.Active management is exciting, while passive management is boring.Investors are overconfident—a normal human condition, not limited to investing. While each investor might admit that it’s hard to beat the market, each believes he will be one of the few who succeed.So, what is the right strategy?In light of the evidence presented, Larry’s advice is clear: avoid the losers’ game. Instead of trying to pick individual stocks or time the market, he advocates...

A retailer in Bangkok was staring down a cash crunch after COVID. He was ready to sign for a loan, convinced it was his only option.Instead, we dug into his numbers and found $30,000 in unsold inventory gathering dust and $8,000 in overpayments to suppliers. That cash was enough to stabilize his business; no debt was needed. The money was there; he just couldn’t see it.Download The Profit Gap for free at TheProfitBootCamp.com to see 5 hidden reasons family businesses work hard but still fall short of profit.Find hidden profit before you borrowWhen cash flow gets tight, panic sets in. Your mind races, layoffs, loans, maybe even shutting down. But fear isn’t a strategy. The truth is, your business is probably sitting on hidden profit, even in tough times. You just need to find it.Start with a zero-based budget. That means you begin each budget line at zero, not last year’s number, and build it up based on what’s actually needed. Each team member justifies every expense from scratch. No assumptions. No carryovers. Just what drives results. Look at your expenses, inventory, and contracts. What’s wasting money?Maybe it’s unused subscriptions, overstocked supplies, or a vendor charging too much. One client found $500 a month in duplicate software licenses. Canceling them took one email and saved $6,000 a year.Cut smart, not deepDon’t just cut costs mindlessly; focus on waste, not muscle. Keep what drives value, like your best staff or marketing, that works. I’ve seen owners slash their top salespeople in a panic, only to tank revenue. Instead, realign spending to what moves profit.For example, shift the budget from low-margin products to high-margin ones. One business I worked with dropped a product line that was barely breaking even. That freed up $20,000 for ads, bringing in $100,000 in new sales.Small wins create momentum. Even saving $1,000 can shift your mindset from panic to possibility. Try this: call your top five vendors this week. Ask for a 10% discount or better payment terms. Most will say no, but some will say yes to keep your business.A client of mine negotiated $5,000 off his annual shipping costs in one 15-minute call. That’s cash you can use to grow, not just survive.Discipline is your secret weaponDiscipline beats loans every time. Borrowing might feel like a lifeline, but it’s a weight around your neck if you don’t fix the root problems. A logistics firm I worked with was desperate for a loan. Instead, we audited their spending and found $8,600 in waste, unused equipment leases, and overpaid utilities. That cash funded a marketing push that brought in new clients without debt. They weren’t out of options; they just needed clarity.Here’s one last story. That same logistics firm thought they were done. But that $8,600 audit changed everything. They used the savings to relaunch ads, landing three new contracts monthly. The owner told me, “I thought we were stuck. Turns out, we just needed to look closer.” What’s hiding in your business?You’ve now faced the five hard truths holding your business back. You know no one’s coming to save you, that delay kills profit, that family dynamics can trap you, that leadership drives results, and that you have options even in a cash crunch. Now, it’s time to act. Pick one step this week, cut an expense, fix a meeting, check your P&amp;L, and do it. Your business depends on you.Actions from prior episodesCut one cost: Block 30 minutes, review P&amp;L, and cut one expense. Just one.

He has prior experience as CFO of Knutsen NYK Offshore Tankers and Umoe Group and Chairman General Partner of MLP KNOT Offshore Partners.STORY: Oeystein has been part of some terrible investments made by his employers. One invested $150 million to become the biggest shareholder of a mine in Guinea, which was lost due to a bad regime. During the great financial crisis, another invested $300 million into a bioethanol plant in Brazil.LEARNING: In a dynamic industry like shipping, you must think more about adapting and being tactical rather than strategic.&nbsp;“You have to be really disciplined when you are in a cyclical industry. Observe where the market is going, and learn how to adapt.”Oeystein Kalleklev&nbsp;Guest profileOeystein Kalleklev is the outgoing CEO of Flex LNG (NYSE/OSE: FLNG) and Avance Gas (OSE: AGAS). He has prior experience as CFO of Knutsen NYK Offshore Tankers and Umoe Group, as well as Chairman General Partner of MLP KNOT Offshore Partners (NYSE: KNOP).Worst investment everOeystein has been part of some terrible investments. In one case, a family Oeystein worked for had invested about $150 million to become the biggest shareholder of a mine in Guinea. The country was under an unstable regime, and the leader was assassinated. There were also so many operational hiccups operationally. That $150 million turned out to be like $3 million when they sold their last share.He has also been involved in bioethanol production in Brazil, where a company he worked for invested about $300 million into a bioethanol plant in Brazil during the great financial crisis. The bosses had to restructure the whole company, and Oeystein had to go to the US to talk to bondholders, trying to get them to choose whether to become shareholders or take a big hit on the bond loans.In another case, Oeystein was involved in a nickel mine in the Philippines where the company he was working for was building a floating production ship for oil. The budget was $280 million, but the company spent $500 million on that building project, and it also took one and a half extra years to complete.Lessons learnedWhen you have such a dynamic industry as shipping, you must think more about adapting and being tactical rather than strategic.Focus on running your ships efficiently—it’s a critical success factor.Shipping is a lot about market timing. Read the market, know where it is going, when you should exit, and when you should invest.You have to be knowledgeable about technology because technology changes quite often in shipping.Be smart about running a shipping company. Do it lean and follow the technology.Andrew’s takeawaysIt’s hard to set a long-term strategy in an industry such as shipping because you’ve got to adapt to what’s happening in the market.You have to run ships efficiently, or else you will miss the core aspect of your business.Actionable adviceIf you want to venture into the shipping industry, you must properly understand shipping because it’s not as straightforward as people think. It’s not just about moving goods from A to B.No.1 goal for the next 12 monthsOeystein’s number one goal for the next 12 months is to read more books to be on top of contemporary issues and be a successful shipping...

I once sat down with a furious business owner. “My team’s useless,” he said. “They never deliver.” I asked him two simple questions: “Who hired them? Who sets their goals?”He went quiet. He admitted he hadn’t run a proper meeting in months, and his priorities changed weekly. His team wasn’t failing; they were confused.Once he got clear and consistent, everything shifted. Execution improved, morale spiked, and profit followed. The problem wasn’t his team; it was his leadership.Download The Profit Gap for free at TheProfitBootCamp.com to see 5 hidden reasons family businesses work hard but still fall short of profit.It starts with youWhen the same issues keep popping up: missed deadlines, low margins, and sloppy execution, it’s easy to blame your team or the market. But nine times out of ten, those problems point to your systems, not your people. If your business feels stuck in a loop, you haven’t built the structure to break free. Leadership isn’t about charisma or barking orders. It’s about clarity and follow-through.Start by auditing yourself. Are your priorities clear to your team? Do you track progress, or just hope things get done?I’ve seen owners delegate tasks and then forget about them, leaving their teams guessing. That’s not leadership. That’s abdication. One client delegated a pricing review but never checked in. Six months later, nothing had changed, and they’d lost $50,000 in potential profit. Set clear goals, assign owners, and follow up. It’s not sexy, but it works.Fix your meetings, fix your profitHere’s a game-changer: fix your meetings. Most business meetings are a mess, with endless venting or no focus. Better meetings lead to better profit. Try this: run one weekly meeting with a tight agenda. Pick one metric, like cash flow, gross margin, or overdue invoices, and identify three actions to move them.One client’s meetings were just complaint sessions. We set a new rule: every meeting ends with three clear next steps. Four weeks later, the execution was sharper, and he told me, “We didn’t need more staff, just a real plan.” Focused action works.Build momentum with better habitsYou don’t need a new team, just better habits. Your people are probably capable, but they need direction. A weekly rhythm, like Monday priorities, Wednesday short check-ins, and Friday results, builds momentum fast. It’s not about working harder; it’s about working smarter. And start writing down what works. That’s your playbook for scaling.One owner I know documented his best sales process. It took an hour, but it cut training time for new hires and boosted close rates by 10%. That’s leadership in action.You’re leading with clarity now, but what if cash is still tight? In our final episode, we’ll tackle how to turn things around when money’s low and pressure’s high.

Today, Andrew and Larry discuss Chapter 32: The Twenty-Dollar Bill.Chapter 32: The Uncertainty of InvestingIn this chapter, Larry explains the efficient markets hypothesis (EMH) and why successful trading strategies often self-destruct due to their inherent limitations.According to Larry, one of the fundamental tenets of the EMH is that in a competitive financial environment, successful trading strategies self-destruct because they are self-limiting—when they are discovered, they are eliminated by exploiting the strategy.He shares the example of Andrew Lo’s adaptive markets hypothesis, which acknowledges that while the EMH may not necessarily hold in the short term, it does predict that inefficiencies will self-correct over time as arbitrageurs exploit them after publication. This understanding leads us to the inevitable conclusion that financial markets trend toward efficiency in the long run.Efficient markets rapidly eliminate opportunities for abnormal profitsTo demonstrate how the efficiency of markets rapidly eliminates opportunities for abnormal profits, Larry shares the following example:Imagine that an investor discovers that small-cap stocks have historically outperformed the market in January. To take advantage of this anomaly, that investor would have to buy small-cap stocks at the end of December, before the period of outperformance. After achieving some success with this strategy, other investors would take note—with the large dollars at stake, Wall Street is quick to copy successful strategies. An academic paper might even be published. Since the effect is now known to more than just the original discoverer of the anomaly, one would have to buy before others do to generate abnormal profits. Now, prices start to rise in November. But the next group of investors, recognizing this was going to happen, would have to buy even earlier.As you can see, the very act of exploiting an anomaly has the effect of making it disappear, making the market more efficient. This underscores the significant role investors play in shaping market efficiency.Behave as if equity markets are...
