It depends. Long term, more than 2 years then I will defenitly keep it. Less than that I will sell, but will first wait for a +-5% recovery, if it doesnt happen in the next couple of weeks I will sell. However I can see some trading opportunities. Only my opinion.
Investors do need to consider the time value of money. I would really only sell now if I intended to buy something else in this market. No point giving in to fear, in fact, I have long learned to do exactly the opposite of what my nerves tell me. There are plenty of support levels out there for Sasol, and I personally believe that every investor should have a bit of trader in them. At these levels, you are still up from last year, so SOL is still technically making higher lows. And if you look at a monthly chart - it is screaming buy me. Just needs a bit of confirmation.
