Kase Studies

What are the Kase Studies?

The Kase studies are a suite of volatility-normalized tools developed in the early 1990s by Cynthia Kase, a chemical engineer turned energy trader. The unifying idea is to measure price movement in volatility units across a scan of lookback lengths, so signals adapt to conditions rather than being retuned per market. The best-known members: the Kase Peak Oscillator, momentum built from statistics that compare volatility-normalized up-moves and down-moves; KaseCD, a MACD-style histogram of the peak oscillator used for divergence work; and Kase DevStops, trailing stops placed at standard-deviation multiples of a two-bar true range, adjusted for the skew of range distributions.

The signature signal is the 'peak out': a peak oscillator reading beyond a threshold derived from its own history (commonly around two standard deviations), flagging a statistically stretched move as an exhaustion candidate. The studies grade the quality of a move, how far price traveled relative to what its volatility calls normal, rather than forecasting direction.

How traders use it

• For exhaustion candidates: peak-out flags and divergences between price and KaseCD mark statistically overextended momentum, read as a cue to tighten risk rather than an automatic reversal.
• For exits: DevStops trail at volatility-scaled distances in the same family as other volatility stops, with the outer lines granting a trend more room at the cost of giving back more on the turn.
• As a cross-market read: volatility normalization means the same thresholds are intended to transfer across instruments and timeframes without re-tuning, one of Kase's stated design goals.
