Choosing which stocks to invest requires effort. Do what one knows is best and to do it gladly.
There are always people who know what is going to happen before it happens and they either start selling or buying ahead of the event, or rumours are triggered and people in the loop take early positions. The last thing you want to do is over-pay because you see a stock moving and think you are missing the boat.Some traders make a little money in the short term but lose big money in the long term. You cannot expect to jump into the market anytime and reap gains out of it.Patiently stay in cash until the market crashes.
Good luck and safe trading
