Scan 5,000+ stocks daily for parabolic short setups. Overextended moves with volume climax and momentum divergence detected. Each setup graded A+ to B.
Run this scan →Parabolic moves represent the final exhaustion phase of a trend — the point where price acceleration becomes unsustainable and a sharp reversal becomes increasingly probable. These extended moves occur when speculation overtakes rational valuation, driving a stock far beyond any reasonable measure of fair value. The parabolic short scanner identifies these overextended stocks approaching the moment of maximum vulnerability.
The psychology behind parabolic exhaustion follows a predictable pattern. As a stock accelerates higher, each new high attracts more momentum chasers, creating a feedback loop of buying. Late-stage buyers are driven by fear of missing out rather than fundamental analysis. Volume often reaches climactic levels as the last buyers rush in — but this surge in activity also marks the point where the pool of remaining buyers is exhausted.
Momentum divergence is the key warning signal. When a stock makes new price highs but momentum indicators like RSI begin making lower highs, it signals that the rate of buying is slowing even as price continues higher. This divergence, combined with extreme extension above moving averages and climactic volume, creates the conditions for sharp mean-reversion moves. Parabolic reversals can be violent — stocks that rose 50% in two weeks can give back the entire gain in days.
The study of parabolic moves and mean reversion in stocks has roots in the work of J. Welles Wilder Jr., who created the Parabolic SAR indicator in New Concepts in Technical Trading Systems (1978). The concept of shorting overextended stocks was further developed by Jesse Livermore in the early 20th century and later by short sellers like Jim Chanos and David Einhorn. Modern quantitative mean-reversion strategies have validated the statistical edge of fading extreme extensions.
Our scanner evaluates the following criteria when detecting Parabolic Short — Overextended Reversal setups across 5,000+ stocks daily.
For parabolic shorts, an A+ grade means the stock is extended 50%+ above its 50-day MA with climactic volume, RSI above 80, and momentum divergence forming on the daily chart. This is not a prediction of future price movement — it is a way to prioritize which charts deserve your attention first.
Enter short when momentum divergence is confirmed (RSI making lower highs while price makes higher highs) and the stock shows its first significant red candle on volume after the climax.
Place stop above the parabolic high. Parabolic squeezes can extend further than expected — never add to a losing short position in a parabolic stock.
First target is the 20-day MA; second target is the 50-day MA. Parabolic reversals often retrace 50-62% of the entire parabolic advance within days or weeks.
