Maybe I'm just being cheap, but do other short term/ swing traders diversify among a few given stocks (2-3) when they swing trade or is it in and out of a select stock they have done their DD on and feel is a winner? Curious if that is the better route in case of a bad call to help hedge? Thanks in advance.
If you picked a stock to play, why would you "throw in a couple more stocks just for the heck of it"? Similar stock? Same sector? If you want to take the "shotgun" approach, trade the ETF.
I keep up with multiple ETF's from different sectors as it would be be pointless to trade similar stocks withing same. I'm taking from your answer that diversifying for short term trades wouldn't be something you'd advocate?
Diversification to mitigate risk would be the mindset of an investor. Having several positions on because of good setups is the mindset of a trader.
