You dont have to worry. Of course there is a wise way to deal with stock conditions that have fallen drastically.

It is very common for the stock market to go down when negative sentiment circulates. The condition that often occurs is panic selling.  Even if the stocks drop below their usual price, be careful in sliding. Do not buy when the stock price is falling, you should be patient to wait until the panic is over and the stock price is stable. Panic in the market will always have an end. When the market starts to reverse from red to green, you can start to look at interesting stocks to collect at discounted prices.

Another way you can do this is to keep the shares you already own. Especially if you already have large market cap stocks with good fundamentals.
