An excellent article on why we should buying stocks now, though we hesitate..
As the author says,

When new clients come to me, I ask them a few questions about risk. One is “What would you do if the value of your stocks fell by 50%?”

The vast majority answer that they would buy more stocks. So now that the market has lost about 40% of its value, why are some of these same clients clamoring to sell?

Well it depends. When the markets are such, and you enter at this point, we often end up catching a falling knife. I caught a couple, and am still bleeding. I have convinced myself that I will not sell them for 3-4 years, but it still hursts you see.

Your investment strategy should instead be based on your goals, your time horizon and what you’ve saved so far. Success will come from sticking to your plan.
