As it's been said over and over by numerous financial experts, you cannot time the market. That's the approach I take with my investments, and over the long haul it has always worked out as history shows. Still given that fact it often gets difficult to maintain your long term investments when things head south, and that fear and panic is what can drive the market down further. History also shows that most investors that sell off their holdings in difficult times most often then miss out on the market rebound that later comes. So I am not much of a trader, I buy and hold the majority of my investments and it all works out in time.
