Conclusion: The ABCs of Behavioral Biases
During this series, we have learned that our own behavioral biases are often the greatest threat to our financial well-being.
The collapse of First Republic Bank is a harsh reminder that any stock can go to zero, no matter how established a company is, or how loyal and wealthy its customers are. The failure of what many considered to be a rock-solid regional bank should serve as powerful evidence of the importance of diversification, what I consider to be one of the first principles of investing.
If your wealth is highly concentrated in any one individual stock, take this opportunity to learn an important lesson: While many people think they know more than other investors, none of us knows more than the market.
Many years before he became a Nobel laureate, my friend and mentor Merton Miller used to say, “Diversification is your buddy.” Diversification is the practice of spreading investments across a variety of assets. It is a time-tested strategy to mitigate risk. Children learn about it early in life with the phrase “Don’t put all your eggs in one basket,” but all too often, grown-up investors forget.
I think it is safe to assume that the total value of the stock market will not go to zero. But the same cannot be said about any individual stock, no matter how promising the future of a company might seem. Why not? Because we cannot predict the future.
The current price of any stock reflects the value of all its future income streams, but it is no guarantee. Some companies fail. Can anyone predict which ones? Fortunately, there is no need to. You can have a positive investment experience without knowing what is going to happen with any individual stock because of diversification. In investing, diversification is the closest thing any of us can have to a free lunch.
Nearly all investing horror stories start with a simple fact: Someone took too much risk. In the case of First Republic, management took too much risk. But investors do not have to. Anyone who lost their shirt when FRB stock lost its value had too much invested in it. Everyone who invests in the stock market should prioritize diversification in their portfolio. And it is never been easier to do so, because with mutual funds and ETFs, many of which allow you to invest in a broad range of stocks by buying just one security, you can achieve a high level of diversification with the same number of clicks as buying a single stock.
In my opinion, when you concentrate your wealth in single stocks, you are gambling, not investing. And that is fine, as long as you do not mind losing what you bet. First Republic has been included as part of the S&P 500 index since 2018. On the day JP Morgan Chase announced that it was taking over the troubled bank, how did First Republic’s dissolution impact the S&P 500? (1) When the market closed, the index was down 0.039%. (2)
Now do you see why diversification is your buddy?

RISKS
Investments involve risks. The investment return and principal value of an investment may fluctuate so that an investor’s shares, when redeemed, may be worth more or less than their original value. Past performance is not a guarantee of future results. There is no guarantee strategies will be successful.
