The Uselessness of Following the Crowd

The single most useless thing an investor can do is worry about what everyone else is worrying about. Conversely, there's no point in getting excited about something everyone is eagerly anticipating because it's likely already "priced in" to the stock market. The stock market moves much faster than the real economy.

  • Priced In: When the vast majority of investors agree on a future event, the stock market starts trading as if that event is already a reality.
  • Example: If everyone believes the economy is slowing, stocks will trade as if the slowdown is already happening.

Economics 101 and the Efficient Markets Hypothesis (EMH)

Basic economics can be useful for managing money, but economists often take an "ivory tower" approach, prioritizing models over empirical data. The Efficient Markets Hypothesis (EMH) states that stock prices reflect all available information at any given moment.

  • Efficient Markets Hypothesis (EMH): Stock prices immediately adjust to reflect new information, making it impossible for stock pickers to gain an edge.
  • Index Fund Advocates: EMH is often cited by index fund advocates who believe individual stock picking is essentially gambling.
  • Unknown Unknowns: The extreme version of EMH suggests that only "unknown unknowns" (Donald Rumsfeld's term) can move stocks, making investing a game of chance.

Index Funds vs. Individual Stocks

While Kramer acknowledges the usefulness of index funds, he argues that markets are not perfectly efficient and often irrational. This inefficiency creates opportunities for individual stock pickers.

  • Index Funds: Best for the vast majority of people, especially for retirement accounts. Safe way to gain equity exposure.
  • Individual Stocks: Require real work and discipline but offer the potential to beat the averages.
  • Kramer's Track Record: Kramer claims to have consistently beaten the averages at his hedge fund, achieving a 24% compound annual return after fees versus 8% for the S&P 500 over 14 years.

The Mad Money Version of EMH

Kramer presents his "quality kind of sort of efficient markets correlary": When there's a widely held consensus view, assume it's already being discounted by the stock market.

  • Example: If everyone is euphoric about a strong job market, that's likely already priced into stock prices.
  • Group Think: It's easy to fall prey to group think, but by the time a consensus emerges, the move is probably over.
  • Focus: Worry about the things other people don't seem to care about, as the real threat is the one you don't see coming.

Question from Mary in Idaho

Mary asks at what percent increase in a stock should a person consider taking some or all of their profit either to reinvest immediately or to just hold back as cash to buy something down the road. Kramer responds that if a stock has fundamental differences from when he bought it, for example, it has two bad quarters, then that is when he wants to sell. He ranks the stocks and lowers the stocks ranking if they've missed a couple of quarters and then he boots that to buy something he thinks is better.

Question from Dave in Colorado

Dave asks how his girlfriend in her early 60s should construct a portfolio of her own and over what time frame should she make the change. Kramer responds that he would put two-thirds of it in an S&P index fund. Then one-third he would structure around a portfolio of say six to 10 stocks of which two or three can be overweighted and large mostly mag seven stocks that we think are really great.

Active vs. Passive Investing

Kramer discusses different approaches to investing, emphasizing that regular people with full-time jobs don't have time to stare at the tape all day.

  • Timing the Market: Trying to call every gyration in the averages.
  • Trading Around a Core Position: Lightening up on part of your position when it gets overextended and buying it back when it sells off.
  • Waiting for a Market Sell-Off: Picking up favorite stocks for much less than they're worth.
  • Index Funds (Reiterated): If individual stocks seem too daunting, stick with low-cost index funds or ETFs.

Managing Individual Stocks Part-Time

If you want to profit from individual stocks without the stock market taking over your life:

  1. Accept "Good Enough": Don't try to buy or sell at the perfect moment.
  2. Buy and Homework: Keep researching your companies after you own them.
  3. Buy Slowly, Sell Gradually: Buy stocks slowly on the way down and sell them gradually on the way up.
  4. Be an Investor, Not a Trader: Don't flit in and out of stocks with every gyration.
  5. Stick with Your Convictions: Be willing to sit tight with the stocks you believe in.
  6. Ring the Register: When your stocks surge higher, take some profits off the table (e.g., after a 20% move).
  7. Buy the Dips: When your stocks get hit, put that cash to work buying more shares at lower prices.

Signal vs. Noise

It's crucial to separate the "signal" (meaningful moves) from the "noise" (insignificant fluctuations) in the stock market.

  • Overbought/Oversold: Stocks can become overbought (rallying too far, too fast) or oversold (coming down too quickly), leading to pullbacks or bounces that don't necessarily reflect fundamental changes.
  • Obvious Signals: A company reports a blowout quarter and its stock roars, or an analyst cuts estimates and the stock plummets.
  • Unusual Signals: A company catches an analyst downgrade and its stock goes up, or a company reports a fantastic quarter and the stock gets slammed.
  • Fundamentals: Take your cue from the fundamentals of the underlying company, not just day-to-day gyrations in the share price.

Question from Howard, New York

Howard asks when to start trimming, how much to trim, and when can he get back in. Kramer responds that discipline must always trump conviction. He likes to start trimming 20% at 20% up. He'll trim between 5 and 10%, another 20%. Same thing. If he really wants to be able to be in shape to be able to buy some back, he must do that.

Question from Ned in Ohio

Ned asks about Warren Buffett's comments on high growth rate companies that eventually forge their own anchor. Kramer responds that Nvidia is a really great example because when you look at Nvidia on forward earnings or the estimates, it always looks expensive and then it so far trumps those estimates that when you look backward, it turns out that the stock was selling at a remarkably low price during mobile.

The Dangers of IPOs

Kramer warns about the dangers of the IPO cycle, where exuberance and new stock supply can ultimately drag down the market.

  • Supply and Demand: The stock market is like any other market; too much supply leads to lower prices.
  • 2020-2021 IPO Mania: A wave of new IPOs and SPAC mergers, fueled by government stimulus checks and high-risk speculation.
  • QuantumScape Example: A science experiment looking to develop better battery technology for electric vehicles that came public via SPAC deal and saw its stock soar before collapsing.
  • SPACs: Be skeptical of SPACs, as they can make absurdly overconfident long-term forecasts that the SEC would never allow in a traditional IPO.
  • Selling to Buy: Portfolio managers often need to raise money by selling existing holdings to invest in new IPOs.
  • Caution: Be cautious when IPOs are coming hot and heavy, as the cycle tends to burn out and weigh on the market.

Doing the Right Thing for the Wrong Reasons

Be careful about doing the right thing for the wrong reasons. Just because a stock goes up after you buy it doesn't necessarily mean your initial thesis was correct.

  • Consumer Packaged Goods (CPG) Example: You buy Proctor & Gamble because you believe in the management and dividend, but the stock rallies due to a sector rotation into recession stocks.
  • Rotation: CPG stocks often roar higher when we get lousy economic data, as they are seen as recession-resistant.
  • Confirmation Bias: When new evidence seems to prove your thesis correct, approach that feeling with skepticism.
  • Residential Solar Example: Residential solar stocks soared in 2020-2022, but then got crushed in 2023 when people realized the industry was built on financing, not just renewable energy.
  • Interest Rates: The residential solar industry was heavily reliant on low interest rates, and when rates rose, the stocks collapsed.

Q&A with Jeff Marks

Kramer brings in Jeff Marks, his portfolio analyst, to answer viewer questions.

  • Identifying the Best Companies: Look for companies with the highest gross margins (indicating a strong moat) and read conference calls to see who's partnering with whom.
  • Too Many Stocks: Diversification benefits diminish beyond 5-10 stocks.
  • S&P 500 vs. Total Stock Market Index Fund: John Bogle recommended the total stock market index fund for slightly better long-term performance due to diversification beyond the S&P 500.
  • Cutting Bait: Up 20%, do a little sale, then up another 20%, do another sale. Let your great stocks run, but cut off the ones that aren't working.

Conclusion

The key takeaways are to avoid following the crowd, understand the difference between signal and noise, be cautious about IPOs, and understand why a stock is moving before assuming your initial thesis was correct. Diversification, homework, and discipline are essential for successful investing.
