Momentum & Volatility Signals
Two different market-behavior signals. Momentum measures direction and trend strength. Volatility measures how large and unstable the price moves are, regardless of direction.
Neutral / mixed momentum
Low movement
A high momentum score means price has been trending upward with confirming short- and medium-term strength. A low score means downward or weakening momentum.
A high volatility score means larger, less stable price swings. It can happen while a stock is rising or falling, so high volatility is not automatically bullish or bearish.
Important: the volatility score above is based on realized price volatility. Implied volatility (IV) comes from options prices and represents the market's expected future movement. Wall Street Score will keep IV separate and will only display it when a verified options-chain feed is available.
