Trading glossary
Overbought and oversold describe conditions where an asset may have moved too far too fast, as flagged by momentum indicators like the RSI.
Overbought and oversold are labels used in technical analysis to describe when an asset's price may have moved far or fast enough to look stretched. An overbought reading suggests price has risen sharply and could be due for a pause, while an oversold reading suggests a steep decline that might slow. These are relative observations about pace, not statements about fair value.
These conditions are typically identified with oscillators such as the relative strength index or the stochastic oscillator, which move within a fixed range. With the RSI, for example, readings above 70 are often called overbought and readings below 30 oversold, though these thresholds are conventions that analysts adjust. The indicator translates recent price behavior into a bounded number for easier comparison.
An overbought or oversold reading is not an automatic signal to act. During a strong trend, an asset can remain overbought or oversold for an extended stretch while the move continues. Many traders therefore treat these readings as prompts for closer study rather than triggers, and combine them with trend and volume analysis. The labels describe conditions, not guaranteed reversals.
With the relative strength index, readings above 70 are commonly called overbought and below 30 oversold. These levels are widely used conventions that analysts may adjust to suit different markets or timeframes.
No. An oversold reading flags that price has fallen sharply, but the decline can continue. In strong trends, assets can stay oversold for a long time, so the reading is a prompt for analysis rather than a signal.
