@bonnieb Here's why it's unlikely to work:
You are not generating any net alpha with your trading strategy. For example if you hold a basket of stocks which are representative of the overall market. For simplicity, let's assume the stock prices follow a random walk. Meaning prices can go up or down at a given point with equal probability. In this case, the expected value of your gains is 0. I can try working out the math if I sit on it for a few hours.
In the real-world, you will still make gains is if the market is going up - but you're not making any alpha over the market because you don't have any specific information the market doesn't know about. A simple way to try it out is to backtest your strategy on historical market data and see what results you get
