What's Really KILLING Your Stock Market GAINS?

Successful investing requires understanding that even excellent stocks can lose money when purchased at the wrong time, so investors should focus on market timing rather than just stock selection; the key principles are: (1) great stocks can still lose money during market downturns, (2) investors should avoid fighting against the market current and instead work with market momentum, and (3) confirmation (waiting for evidence that market demand is returning) is more reliable than conviction (personal predictions about market timing).
