Measuring Our Stock Trading Profit

The Starter Investor Measures Trading Performance

Effective from our update on April 5, 2023, we have rebranded from Marginal Investor to The Starter Investor. For additional details, please visit our About Us page.

KEEPING TAB OF OUR TRADING PROFIT is more about tracking our success in the stock trading game. But how do we measure our accomplishments?

Reinvestment

"In a continuous program" says Benjamin Graham, the author of The Intelligent Investor: The Classic Text on Value Investing, "no market profit is fully realized until the later reinvestment has actually taken place."

Trading profit

In more concrete terms, the "true measure of the trading profit" Graham says in Chapter Two entitled The Investor and Stock-Market Fluctuations, "is the difference between the previous selling level and the new buying level."

For illustration, let us use the completed stock trading operating cycle mentioned in a previous post on  BPITrade Updated Fee Structure:

This shows a trading profit of almost 8 percent based on our previous total sell price. Just maintain similar results in the next 9 to 12 stock trading roundtrips and you are on your way to doubling your money probably.
