NVDA Bull Flag: what happens next

A sharp impulse up (the pole) followed by an orderly, slightly-down consolidation channel (the flag).

The honest historical base rate for the bull flag pattern, plus NVDA's current shape cohort. These are empirical base rates, not predictions. Chart shape predicts the size of the next move more reliably than the direction. Not financial advice.

Bull Flag base rate

Across 21,133 detected bull flag patterns in the database (all symbols, ~10 years). The honest test of the textbook read.

Forward returns are measured from the detected pattern bar. Average confidence of detected bull flags: 0.68.

How a bull flag is detected

The detector requires a pole of at least 6% over 25 bars or fewer, then a flag of 20-60 bars that retraces less than 25% of the pole, slopes gently down, and fits a clean line (R-squared >= 0.6) with declining volume. The classic textbook read is continuation higher — the base rate below is the honest test of that.

NVDA current shape cohort

Separate from the pattern base rate above: this is the empirical forward-return distribution of 273 historical analogs of NVDA's recent chart shape as of 2026-05-20 (timeframe 1d). It is shape-based, not conditioned on the bull flag — included as ticker context.
