Break out of downtrend is not confirmed. Preserving cash
Traders are closing the week liquidating to cash which is currently safer than equities. "Best to not fight the tape". The trend is your friend. Would not short personally because the rebound, when it arrives, might be violent and after after hours or circuit breaker events. Many shorts were wiped out during the financial crisis blindsided by massive government intervention. Great times to be a trader. Enjoy it while it lasts.
