Take extreme care when someone makes a bold prediction about anything – including the investment markets. Chances are the predictions could be well off mark.

And, poorly-informed investors who readily accept such predictions are putting their finances at risk.

An investment research commentary from Vanguard in the US recently repeated these gems from the archives of infamous investment forecasts:

  • The Dow Jones will hit 36,000 – a prediction from the 1990s. (It now sits at about 11,500.)
  • The US real estate market will not go bust – a prediction from 2006. (And we all know what happened to the American residential market during  the GFC and its aftermath.)

“It’s common to hear forecasters who make mistakes argue that they were not really wrong – they were just off on the timing,” Phillip Tetlock, a professor of management and psychology at the University of Pennsylvania, is quoted as saying in the Vanguard commentary.

Tetlock is a world-class specialist on forecasters who make lousy predictions. In fact, he is well-known for spending years tracking the predictions of 284 “experts” who made 28,000 predictions across a range of topics.

“As a whole, experts were slightly more accurate than the proverbial dart-throwing chimpanzee,” Tetlock concluded.

Sadly, it seems that some people feel almost obliged not to ignore the forecasts of others. “There is a deep-rooted need to believe that we live in a predictable and controllable universe,” Tetlock commented. “…people anticipate intense regret – and a lot of blame – if they failed to heed authoritative-sounding advice that turned out to be accurate.”

The message from all of this for investors is to become as informed as possible and be suspicious, highly suspicious, of any bold investment tips or predictions.
