Creux en V Complete Guide

What is Creux en V?

The V-Bottom, also known as a 'Spike' or 'V-Reversal,' is a powerful bullish reversal pattern characterized by a sharp, aggressive decline followed by an equally rapid recovery. Unlike more gradual patterns like the Double Bottom or Cup and Handle, the V-Bottom lacks a period of consolidation or 'basing' at the low. It typically forms during periods of extreme market volatility or in response to sudden, high-impact news events that trigger panic selling. According to Thomas Bulkowski’s research in the 'Encyclopedia of Chart Patterns,' the V-bottom is one of the most difficult patterns to identify in real-time because the 'turn' happens so quickly. The pattern begins with a steep downtrend, often accelerating into a selling climax. At the lowest point, the price hits a 'spike' low on exceptionally high volume, signaling that the last of the sellers have been exhausted. This is immediately followed by a sharp price surge, often on high volume, as buyers aggressively step in. Bulkowski’s data suggests that while V-bottoms are common, they have a failure rate of approximately 18% in bull markets when looking for a 10% price rise. The average rise following a confirmed breakout is roughly 38%. For a V-bottom to be technically valid, the recovery should retrace a significant portion of the prior decline, ideally breaking above the previous 'peak' that started the final plunge. Traders often look for a 'one-day reversal' candlestick or a 'tower bottom' (as described by Steve Nison) at the pivot point to confirm the shift in momentum. Because of the lack of a base, risk management is critical, as the rapid ascent can just as easily fail if buying pressure dissipates.

Identification Rules

1. Prior Trend: A steep, nearly vertical downtrend must precede the bottoming spike.
2. Pivot Point: A sharp, single-day or single-bar 'V' shaped turning point with no horizontal consolidation.
3. Volume Climax: A significant surge in volume at the absolute low, indicating a selling climax or capitulation.
4. Reprise symétrique : La remontée subséquente des prix devrait être aussi vive et agressive que la baisse précédente.
