Gauging Market Momentum

Price alone doesn't tell the full story. Momentum indicators reveal the speed and strength behind price moves — often warning you a reversal is coming before price itself confirms it.

RSI: Relative Strength Index

RSI? is a 0-100 oscillator measuring the speed and magnitude of recent price changes. It answers: is this move getting stronger or running out of gas?

• RSI > 70: Overbought. The stock has rallied hard and fast. Not a sell signal on its own, but a warning that buyers may be exhausted.
• RSI < 30: Oversold. The stock has been hammered. Potential bounce territory — but in a structural downtrend, RSI? can stay below 30 for weeks.
• RSI 50 Level: Often acts as a trend filter. In strong uptrends, RSI? tends to hold above 50. Losing 50 during an uptrend is an early warning sign.

The most powerful RSI? signal isn't the overbought/oversold reading — it's divergence.

MACD: Moving Average Convergence Divergence

MACD? shows the relationship between two exponential moving averages (default: 12-period and 26-period EMA). The MACD? Line is the difference between them. The Signal? Line is a 9-period EMA of the MACD? Line.

• Bullish Crossover: MACD? Line crosses above the Signal? Line — short-term momentum overtaking long-term momentum. Often used as an entry trigger.
• Bearish Crossover: MACD? Line crosses below the Signal? Line — momentum is weakening.
• MACD Histogram: The bar chart showing the distance between the MACD? and Signal? lines. When the histogram shrinks while price keeps rising, momentum is fading — even if price hasn't turned yet.
• Zero Line: MACD? crossing above zero means the short-term EMA is above the long-term EMA — a bullish structural shift.

The biggest mistake traders make with MACD?: using it as a sole entry trigger on choppy, sideways markets. MACD? is a trend-following tool. In a sideways market, it generates endless false crossovers.

Stochastic Oscillator

The Stochastic compares a stock's closing price to its price range over a set period (default: 14 days). It outputs two lines: %K (fast) and %D (slow).

• Above 80: Overbought zone.
• Below 20: Oversold zone.
• %K crossing above %D in oversold territory: Bullish trigger.
• %K crossing below %D in overbought territory: Bearish trigger.

Stochastics work best in range-bound markets where price oscillates between levels. In strong trending markets, a stock can stay overbought for an extended period — shorting because "Stochastic is at 85" into a ripping trend is a costly mistake.

Divergence: The Highest-Value Signal

Divergence occurs when price and an indicator disagree about what's happening.

• Bearish Divergence: Price makes a higher high, but RSI? or MACD? makes a lower high. The momentum behind the rally is weakening even though price looks fine. Often precedes a correction.
• Bullish Divergence: Price makes a lower low, but RSI? or MACD? makes a higher low. Selling pressure is exhausting even as price looks terrible. Often precedes a bounce.
• Hidden Bullish Divergence: Price makes a higher low (uptrend intact), but RSI? makes a lower low. A pullback that looks weak on the indicator but is actually a healthy retest. Strong continuation signal.

Divergence is most reliable when found at a key support or resistance level. A bearish divergence at major resistance is significantly more meaningful than one in open air.

Combining the Three

No indicator works in isolation. A high-conviction momentum setup looks like:

• RSI? recovering from below 30 and crossing above 40 (momentum shift)
• MACD? bullish crossover forming while histogram turns positive
• Stochastic %K crossing %D from oversold territory
• Price bouncing off a known support level

When all three align at a technical level, that's a confluence signal — not a guarantee, but a statistically meaningful edge.
