The risk-reward ratio answers a question most people skip: not \u201cis this a good stock?\u201d but \u201cis this a good price to buy it at today?\u201d Those are different questions, and confusing them is one of the most common ways retail investors lose money on genuinely good companies.
Every trade has two distances. The distance from the current price down to where you would admit you were wrong and sell — your stop-loss. And the distance from the current price up to where you would realistically take profit — your target.
Divide the second by the first, and you have the risk-reward ratio.
Here is the part that surprises people. With a 3:1 ratio, you can be wrong more often than you are right and still make money. Lose four trades at ₹5 each (₹20 lost), win two at ₹15 each (₹30 gained), and you are ahead — despite a losing record.
Flip it around. With a 0.5:1 ratio, you have to be right roughly two-thirds of the time just to break even. Very few people are.
This is the crucial point. A stock can have a perfect chart — strong uptrend, healthy momentum, every signal firing — and still be a poor buy today, simply because it has already run up close to its resistance while its support sits far below.
You would be arriving late. The upside that remains is small; the downside if it turns is large. The company has not changed. The price has.
The ratio is only as good as the levels it is built from. If a stock has no meaningful support anywhere near the current price — common in stocks that have gone parabolic — then any stop is a guess, and the ratio computed from it is arithmetic rather than a real read of the chart. Treat those numbers with scepticism.
