Here are some very compelling reasons why we prefer to trade e-mini YM to stocks (off the top of my head).
-I can day trade without needing $25,000+ in the account! I have two accounts with about 10K in them.
-Comissions are decent $4/round turn trip on the YM
-Tax Reasons - You don't have to list every sale on your return! (for people in the USA)
-It's liquid enough. Market orders are instant. No weird fills
-The spreads are never going to be huge like they can get on stocks
-Focusing on one instrument day in and day out is less complicated and more productive
-I can sleep in! As I dont have to wake up at 6am and scan for stocks to trade
-Share size allocation is easier. I trade from 3-8 contracts depending on the setup
-I've held a stock that plunged 20 pts due to random company event. While econ reports move the futures. It's never been THAT bad!
-There are always shorts avilable!
-Comissions are reasonable (I pay around $4.10/round trip)
-No uptick rule (not that its going to be lasting too much longer)
-The $5/tick range of the YM makes for lower slippage(ES, ER too volitale=bad slippage)
If anyone has any more to add, then feel free!
