BAC relative volume: the current reading and its track record

Data as of 2026-10-16

BAC’s current relative volume reading and what that signal has historically been followed by.

This page covers Bank of America (BAC) — its current relative volume reading and the measured historical record of what BAC relative volume extremes were followed by.

How to read this. These figures are measured only on instruments currently covered by this site — a set of companies that survived. Signals that appear to have ‘worked’ on the downside are conditioned on these names having recovered; a company that fell and never came back would not be here to measure. Read every number below as a property of this surviving sample, not a universal rule, and never as advice.

All figures are ‘excess’ returns — measured relative to each instrument’s own historical drift, not relative to the market. This is not alpha and not a market-beating claim; it isolates the signal from the instrument’s background trend. Measured from the first day each signal appeared (not its most extreme point), so it reflects what was knowable in real time.

Relative volume showed no measurable forward signal. Across the full sample, episodes on this measure were followed by returns statistically indistinguishable from each instrument’s own drift — this is reported as a null result rather than left out.

When BAC was at a high extreme

Across 217 past episodes where BAC was at a high extreme on this signal, the 216 with a complete 20-session forward window beat BAC’s own trailing drift by 1.40 percentage points on average (55% of those 216 beat drift).

BAC forward excess return vs its own drift after high-extreme relative volume readings, by horizon.
horizon	excess vs own drift	beat-drift rate	episodes with a complete horizon
1 session	-0.01%	52%	217
5 sessions	+0.45%	54%	216
20 sessions	+1.40%	55%	216

When BAC was at a low extreme

Across 107 past episodes where BAC was at a low extreme on this signal, the close 20 sessions later beat BAC’s own trailing drift by 0.32 percentage points on average (52% of episodes beat drift).

BAC forward excess return vs its own drift after low-extreme relative volume readings, by horizon.
