When every man in the street is talking about Nvidia, it's about time to let go. Amongst the 7 I would sell Nvidia and switch to TSLA and Alphabet. Be a contrarian.
Looking at the movements of Chinese stocks in the past few weeks, seems to me there is a lot of selling going on. Most sessions opened high and got sold down. 3-4 down sessions and there would be a rebound. Then the pattern repeats. This saps my confidence. Wouldn't wish to carry babies.
