Trading Mechanics
Profit isn't generated simply by the stock price going up; it's the delta between your entry and your exit. Your initial investment scales that delta. A $5 move on 100 shares generates a $500 gross return.
Taxes, margin interest, and broker commissions are considered frictional costs. They degrade your edge. A profitable trader must generate enough gross margin to overcome the friction of executing the trades themselves.
ROI allows you to compare investments of wildly different sizes. Earning $1,000 profit on a $2,000 risk (50% ROI) represents a vastly superior trading performance than earning $1,000 profit on a $100,000 risk (1% ROI).
