Definition
The McClellan Oscillator is a technical indicator used to measure market breadth by analyzing the difference between the number of advancing and declining issues in a stock market index, notably the NASDAQ. It signals potential shifts in market sentiment and strength in trends via phenomena such as breadth thrusts and divergences.

The formula for the McClellan Oscillator is as follows:
\[
\text{McClellan Oscillator} = \text{(12-day EMA of Advances)} - \text{(12-day EMA of Declines)}
\]
Where EMA refers to the Exponential Moving Average.
Example
Suppose the 12-day EMA of advancing stocks is 150, and the 12-day EMA of declining stocks is 80. Using the formula, we find:
\[
\text{McClellan Oscillator} = 150 - 80 = 70
\]
- Breadth Thrust: A significant upward movement in the oscillator from a negative to a positive value, suggesting a potential strong reversal in market trends.
- Divergence: A situation where the oscillator diverges from the price trend, signaling possible future reversals in price movement.

Frequently Asked Questions
What does it mean when the McClellan Oscillator is above zero?
A reading above zero typically indicates that the market is experiencing bullish sentiment, affirming that more stocks are advancing than declining.
What indicates a breadth thrust on the McClellan Oscillator?
A breadth thrust manifests when the oscillator moves significantly from a negative reading (e.g., below -100) to a positive reading, suggesting a strong price reversal.
What is divergence in the context of the McClellan Oscillator?
Divergence occurs when the oscillator shows contrary signals compared to the market index, hinting at an impending change in market direction.
Who invented the McClellan Oscillator?
The McClellan Oscillator was developed by Sherman and Marian McClellan in the 1960s. No, they were not in a secret banking cabal, just passionate about market breadth analysis! 😉
