Speaking of doubles and such, AMD has a clean and clear floor that it keeps bouncing on, at ~73.80. It looks like thin air from there to ~60 if the floor breaks. The problem is that price often bounces in the middle, rather than a straight line down. However, this type of thin air exists in other tech stocks, albeit not as clearly as on AMD. Thus, I posit that AMD is one of the best choices for a short. The problem is the entry. It's been in the middle of a range, and a floor break can be a false breakout before the real one. This is the type of trade where a smaller position, held for a longer period of time, is the correct technical play.
For what it's worth, I agree with your Nasdaq thesis. It's just that there can a greater drawdown because a large move down has already taken place- yesterday would have been the time to short, due to divergence and such. I think this is just sector rotation, and we have low volume areas below on some tech stocks, which lines up with the fundamental view of beaten down stocks becoming good again due to the corona vaccine.
