What is the McClellan Oscillator and how does it pinpoint broad-market overbought regimes?
By Easy Money Scanner · Educational reference · Not investment advice
The short answer
The McClellan Oscillator is a market breadth indicator derived from advancing versus declining issues, used by technicians to identify overbought or oversold conditions in major indexes.
How it works
It is calculated using exponential moving averages of net advances; extreme positive or negative readings may suggest a market is due for a reversal or consolidation.
An example
A reading above +100 might lead a technical analyst to flag the broader market as potentially overbought and watch for a pullback.
Risk & limitations
Breadth indicators are lagging or coincident in many cases and can stay extreme for extended periods; this is educational content, not a trading signal.
