I'm not a swing trader but sometimes conditions suggest it is a good thing to do. It was the AAPL announcement a couple days and the resulting price action I saw that made me put a bunch of short term shorts on. My view that other stocks that marched up incessantly with AAPL would falter a bit. FFIV , CRM, POT, SNDK, NFLX. ALso watch the ETFs TZA, VXX, FAZ. TNA. Take that for what it's worth.
Here is FFIV taking a trip from $141 down to $107. I’ll take profits here.
