Momentum Indicators and Divergence

Direct Answer

A momentum indicator measures the rate at which price is changing rather than its level, which is why momentum can turn while price is still making new highs. That property is also its most common trap: an overbought reading means momentum has been strong, which in a trending market is what you would expect rather than a reason to fade it. Oscillators built to identify extremes in a ranging market spend long stretches pinned at those extremes during a trend, so the reading is only actionable once you have established which regime you are in.

Does overbought mean a stock will fall?

No. An overbought reading means momentum has been strong, which in a trending market is what you would expect and not a reason to fade it. Oscillators built to identify extremes in a ranging market spend long stretches pinned at those extremes during a trend. The reading is only actionable once you have established which regime you are in.

• Awesome Oscillator: Formula & Signals

  The Awesome Oscillator compares a 5-period and 34-period midpoint moving average to gauge momentum shifts through zero-line crosses and twin peaks.

• Commodity Channel Index (CCI)

  The Commodity Channel Index (CCI) measures how far a security's typical price has strayed from its statistical average, flagging overbought, oversold.

• Hidden Divergence: Trend Continuation Signal

  Hidden divergence forms when price makes a higher low or lower high while momentum makes the opposite move, a pattern some read as trend continuation.

• MACD Divergence: What It Signals

  MACD divergence is when price makes a new high or low that the MACD line doesn't confirm, a possible early warning of fading momentum, explained here.

• Momentum Across Market Regimes

  Momentum indicators tend to work more reliably in trending markets and generate more false signals in range-bound markets, here's why regime matters.

• Momentum Divergence: Meaning & Signals

  Momentum divergence is when price and a momentum oscillator move in different directions at new extremes, warning that the move's underlying pressure may be.

• Overbought and Oversold in Context

  Overbought and oversold readings mean less in isolation than relative to trend and regime, in a strong uptrend an oscillator can stay overbought for a long.

• Percentage Price Oscillator (PPO)

  The Percentage Price Oscillator (PPO) is MACD expressed as a percentage, letting traders compare momentum readings across stocks at different price levels.

• Rate of Change (ROC) Indicator Explained

  Rate of Change (ROC) measures the percentage price change over a set lookback period.

• RSI Divergence Explained

  RSI divergence is when price makes a new high or low that RSI fails to confirm, signaling weakening momentum.

• Stochastic RSI vs. Stochastic Oscillator

  Stochastic RSI applies the stochastic formula to RSI, not price.

• Stochastic RSI Explained

  Stochastic RSI applies the stochastic formula to RSI values, creating a faster, more sensitive momentum oscillator with more frequent signals.

• True Strength Index (TSI)

  The True Strength Index (TSI) double-smooths price momentum into a zero-line oscillator.

• Ultimate Oscillator: 3-Timeframe Momentum

  The Ultimate Oscillator blends buying pressure across three timeframes into one reading, aiming to cut the false divergences single-timeframe oscillators can.

• Williams %R: Formula, Uses & Limits

  Williams %R measures where price closes relative to its recent high-low range on a 0 to -100 scale, flagging overbought and oversold conditions.
