Overbought & Oversold,
the labels people misuse most.

On RSI, overbought usually refers to readings above 70 and oversold to readings below 30. Those thresholds describe unusually strong recent momentum. They do not mean price has become objectively too high or too low, and they do not guarantee a reversal.

Quick answer

Does overbought mean sell?

No. In a strong uptrend, RSI can remain above 70 while price continues rising. “Overbought” is a momentum label, not a valuation judgement or automatic sell instruction.

Why can RSI stay overbought?

Because repeated gains keep dominating the calculation. If price continues rising strongly, the mathematical condition that produced the high reading remains in place.

The same logic applies to oversold readings during powerful declines.

What can an extreme reading still tell you?

It tells you recent momentum has been unusually one-sided relative to the chosen window. That can matter when combined with context such as an extended move, nearby resistance, weakening volume or a divergence between price and RSI.

But none of those combinations removes uncertainty.

Language matters

“Overbought” is not the same as “overvalued”.

RSI knows nothing about earnings, cash flow, assets or fair value. A stock can be fundamentally cheap and technically overbought, or fundamentally expensive and technically oversold.

One is a momentum description. The other is a valuation judgement.
