Absolutely not.. Pre market activity often does not mean much for individual stocks,, Pre market activity on sector is different though ,,,
Why narrow down ? if you end up with 5 stocks then trade them all with much lesser POS size and let them run longer,, This way you have distributed the risk over a range ,,, I myself trade both styles,, fast scalping and Longer runs,,, I scalp fast because of my tools which helps me out a lot and my experience,,,
This pic shown is the example of basket trades on Friday as i explained above,, ( sorry about posting Trades again as I am told it serves no purpose hence no more P/l
