This may seem counterintuitive to the topic of this thread, but I often question myself: Are we learning more than needed from our mistakes, or are we learning more than needed when we are right?
As Prof. Sanjay Bakshi says: Quality of Decision vs. Outcome:
Good Decision and Bad Outcome – Unlucky
Bad Decision and Good Outcome – Lucky (This may be dangerous for long-term investing.)
Two Examples:
Being in Cash: In one meeting, a friend was beating himself up for being just 20% in cash during August/September. His point was that he knew the market peak was coming, so he should have held more cash. He questioned why he restricted himself to 20% and not 40%.
Selling Nasdaq 100 MF Units: Three weeks ago, I sold my entire portfolio of Nasdaq 100, which was 15% of my total portfolio. This decision seems good for now. However, I fear whether I will be able to re-enter the world’s largest market at the right time.
In my view, both decisions seem like Bad Decision and Good Outcome in the short term. However, they may turn into long-term bad decisions if:
Case 1: My friend develops a habit of frequently staying in cash.
Case 2: I fail to re-enter the U.S. market at the right time (as a long-term investor, I am okay with a 12-13% return).
These are just examples, but the point is: Bear and bull market volatility in the short term teaches us wrong lessons, which may be harmful to long-term investing.
I remember reading about Sony in the book Made in Japan. At one time, Sony was not in the calculator business, even though it was considered a highly attractive industry. However, due to its appeal, many players entered the market of calculator manufacturing, turning it into a commodity business, ultimately leading to losses for most companies. At that time, people praised Akio Morita’s foresight in avoiding calculators’ business. However, Morita later admitted that because Sony never entered the calculator business, it missed out on leading the digital/computer industry. He reflected, “I wish we had made the mistake of entering the calculator business.”
Just my random thoughts.
