Yep, its called fear (loss) and greed (profit) with Human emotion thrown in for good measure, The eyes likes green, dislikes red. It can be that simple my friend. Have you ever bought a stock that's going down in a sea of red thinking you may have picked the bottom? That's what people are doing. Some people win, some people lose, its a zero sum game.
In the final analysis, how much can you afford to lose?
If you lose all you chips you cant bet.
That's why they invented Stop Loss triggers.
Good Traders use this to protect their capital.
NIC is being oversold (fear) currently.
If you think its a good stock, you can always buy back in, or If your still holding take the opportunity to average down your SP.
Wait for trend reversal with good underlying support of at least 3 to 4 days. If unsure buy in small parcels on the way back up.
This is just my opinion, not advice.
