The point is this strategy encourages investors to buy shares when the price drops sharply, actually it is not a good time to implement the strategy. Serious economic problems that accompanied the decline in stock prices, pushed the market to be even sharper and needed a long time to recover. There are times when the sharp decline in stock prices Cash provides investors with opportunities. If the patient continues to bleed, it is likely that he will heal long and may even die
It depends on how the investors speculate the next price,it could be very rewarding when we buy low and the price go for a high rising,but some of the project could be stagnant or go lower, so it's really important to do research before buying, don't listen to expert or any friends, you need to make your own decisions when you want to invest,and remember to always have a cutloss strategy
