There are quite a few traders at my firm who scalp NYSE stocks. One guy loves LU. (might not sound like much) but try it on 15,000 shares plus. He's has serious rebates and takes advantages of the cap on commission so he cost is less than .05 per share. He scratches the majority but when he can find the SPOO's really moving he will grab .08 scents.
There is another big trader at my firm who LOVES IBM. He tends to scalp it with 1000-5000 shares minimum and averages .50 daily from him.
I tend to trade different NYSE stocks but it varies on the momentum.
