LEARNING: Do not be swayed by herd mentality.
“Markets can remain irrational longer than you can remain solvent. 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 deeply understands the world of academic research and investing, especially risk. Today, Andrew and Larry discuss Chapter 36: Fashions and Investment Folly.
Chapter 36: Fashions and Investment Folly
In 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 mentality
When 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 bias
According 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 none
Another 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

Cardiac Cowboys
The heart was always off-limits to surgeons. Cutting into it spelled instant death for the patient. That is, until a ragtag group of doctors scattered across the Midwest and Texas decided to throw out the rule book. Working in makeshift laboratories and home garages, using medical devices made from scavenged machine parts and beer tubes, these men and women invented the field of open heart surgery. Odds are, someone you know is alive because of them. So why has history left them behind? Presented by Chris Pine, CARDIAC COWBOYS tells the gripping true story behind the birth of heart surgery, and the young, Greatest Generation doctors who made it happen. For years, they competed and feuded, racing to be the first, the best, and the most prolific. Some appeared on the cover of Time Magazine, operated on kings and advised presidents. Others ended up disgraced, penniless, and convicted of felonies. Together, they ignited a revolution in medicine, and changed the world.
