Update: $UNH drops along with $SPY this afternoon, which ends up with a bearish engulfing bar on the daily chart. If tomorrow $UNH drops again, it will be a short signal. If the whole market goes down, we think it is OK to close the trade. We'll move our stop to the low of $294.5 https://t.co/ptRn2IOJy3 https://t.co/VoXYKn1jwK
