Hi Ahmed,
It is your call whether to sell the stocks in your portfolio or not.
If you are a trader, follow the stoploss concept and exit as soon as the stoploss is triggered.
However, if you are an investor, you could hold the fundamentally good scrips even if the stoploss is triggered. If you do not know whether the stock you are holding is fundamentally strong or not, you should ask seniors like saint.
Thanks,
Balaji.
