Stupidity And The 5-Laws Not To Follow

Human stupidity is the one thing you can rely on in financial markets. I recently read a great piece by Joe Wiggins at Behavioral Investment, which discusses why “Investing is hard.” The entire article is worth reading, but here are the five key reasons investors often fail at investing:

  1. Sensible decisions will frequently make us look stupid,
  2. Crystal balls aren’t enough,
  3. Sentiment can overwhelm everything,
  4. A longer time horizon doesn’t guarantee success, and;
  5. Extremes matter.

These are great points, particularly now that there is ample evidence that investors’ “crystal balls” have failed, with markets continuing to trade at extremes. Last week’s #BullBearReport made such a point.

“At our 2025 Economic and Investment Summit, we discussed the exceedingly high valuations investors pay to own assets. The chart below shows the S&P 500’s current deviation from its long-term, exponential growth trend. At 147%, that deviation is among the highest levels on record and surpasses that of both the “Dot.com” and “Financial Crisis” peaks. Unsurprisingly, investors’ overpayment of future earnings has also pushed current valuations to some of the highest levels on record.”
