VPT Adjustment-Basis Sensitivity

VPT adjustment-basis sensitivity is the dependence of return-weighted volume on adjusted versus unadjusted closes.

Advanced 1 linked topicEvidence-reviewed

Definitions

In plain terms

Corporate actions or price-basis changes can alter percentage returns and therefore the whole cumulative path.

Technical

A revision to a close or split-adjustment policy changes the affected return, its contribution, and the cumulative suffix; the volume basis must also be declared.

Scope

A VPT series is not portable across incompatible price-adjustment policies without recomputation.

Examples

  • A reviewer computes VPT Adjustment-Basis Sensitivity from a small OHLCV fixture and checks readiness, units, and edge cases before publication.

Common misconceptions

  • A VPT series is not portable across incompatible price-adjustment policies without recomputation.
