I have a trading strategy that scans 500 stocks for buy/sell triggers On any given day it can return 30-50 symbols. If I do not have the buying power to take positions in all of these positions...can anyone suggest a way to narrow down the list? What do you think about randomizing the list totally and taking a position in the max number I can get into? Any ideas would be greatly appreciated. I thought about using Beta as a qualifier and only trading the lower beta stocks, but as I posted earlier, I see such a huge discrepancy in the beta values that websites are spitting out.
