People have been predicting a strong bull market for the last 2 years. Every day you can read articles stating it's the right time to jump in and others saying completely the opposite. Everybody's so intent on being right that the only thing that's going to sink the markets is the belief that the markets are sinking. How does a boat sink of a perfectly calm day? Tell everybody to rush to one side to see the view and boat will turn over quite quickly, just like the Victoria steamboat disaster: https://en.wikipedia.org/wiki/Victoria_steamboat_disaster
