How to Read This Table
Each row is one complete trade cycle (BUY → HOLD → SELL). Professor Mean had $8,781.28 at period start. When he sees a buy signal, he uses all available cash to buy shares. He holds until hitting his +5% target, -10% stop loss, or 30-day limit. After selling, the profit/loss is added to his balance, and the next trade uses that new balance.
