What Is Profit and What Is Loss
Simply put:
Profit = When you sell a stock for more than you bought it
Loss = When you sell it for less than the purchase price
But don’t stop there! You also need to factor in commissions, taxes,
and even the time you spend holding the stock — all these impact your net outcome.
The Golden Formula for Profit or Loss
Net Profit/Loss = (Selling Price – Purchase Price) × Number of Shares – Costs
Example:
- Bought 200 shares at $25 = $5,000
- Sold them at $30 = $6,000
- Total trading fee = $50
Net profit = (30 – 25) × 200 – 50 = $950
Must Track
Active Trader? Here’s What You Must Track
Trading differs from investing — it’s fast-paced, high-risk, and demands precision. Think of it as chess in real-time.
Key tips for active traders:
- Track each trade independently
Don’t rely on gut feeling. Use spreadsheets or tools to log your entry, exit, volume, and fees. - Plan your entry and exit points
A smart trader knows in advance where they’ll buy and where they’ll sell. - Use technical analysis
Candlesticks, RSI, moving averages… these are your decision tools. - Review performance weekly
One winning day doesn’t mean success. Evaluate your profit/loss per week or month.
Dividends
Long-term investors should add dividend payments to their total returns.
However, for short-term traders, dividends are usually irrelevant, as they don’t hold stocks long enough.
Can a Winning Trade Actually Be a Loss
Yes!
If you forget to factor in commissions or taxes, you might think you made a profit — but you could actually be down.
Final Advice
- Don’t depend on luck. Rely on data and discipline
- Measure your results with real numbers
- Learn from past trades — refine your strategy
- Let profit/loss be the mirror of your approach
