No one can predict the high or low and no one wants their stock portfolio in red color. 

The first thing you have to do is to identify the bluechip companies or the stocks that have rising trend since inception.

Spot the lows for buying

Sell the stock once it touches 7% or more return

Pro tip: Invest when the market crashes, you will get huge returns after recovery.
