Overbought and Oversold

Also called: overbought, oversold

Conditions where an oscillator says price has risen (overbought) or fallen (oversold) very fast — a stretched move that may pause or reverse.

Schematic of a overbought and oversold — illustrative geometry, not a live price chart.

Overbought and oversold are read from momentum oscillators: RSI above 70 or below 30, the stochastic above 80 or below 20, Williams %R above −20 or below −80. They describe the speed of a move, not a guarantee of reversal — a stretched stock can keep stretching.

The classic mistake is shorting 'overbought' or buying 'oversold' blindly. In a strong trend, oscillators can sit at an extreme for weeks. The conditions are most useful at support or resistance, with divergence, or as a filter for timing pullback entries with the trend.

On StockSetups

Because the RSI, stochastic, Williams %R and MFI on every StockSetups signal are screenable, you can build overbought/oversold filters — for example, pullback setups resetting from oversold within an uptrend.
