Keep price and dividend adjustments consistent
This page uses FMP’s split-adjusted close and its adjDividend field. It does not fall back to dividend-adjusted adjClose: adding cash dividends to a series already adjusted for them risks double counting. The calculated share quantity is in the provider’s adjusted share units, not necessarily the literal number of historical shares purchased.
Dividend timing and the holding interval
The first returned close on or after your start date is the entry; the final close on or before your end date is the exit. Both are displayed. Dividends with ex-dates strictly after entry and through exit are accrued without reinvestment. Buying on an ex-date does not earn that dividend in this model. Payment can occur after exit, so the allowance is not a statement of cash received by the end date.
A synthetic example you can reproduce
Assume 1,000 USD, a split-adjusted entry close of 10, an exit close of 11 and one eligible adjusted dividend of 0.50. The holding has 100 adjusted share units, price value 1,100 and dividend allowance 50. Modeled ending value is 1,150, or a 15% holding-period return. These numbers are hypothetical and are not PG observations.
Annualized return = (modeled ending value / initial amount)^(365.25 / elapsed days) − 1. It expresses a constant equivalent rate; it does not imply a smooth path, dividend reinvestment or predictable future returns.
Coverage and exclusions
Requests are limited here to ten years. A response needs at least two valid dates and must reach within seven calendar days of each requested boundary. The boundary check is a data-quality guard, not evidence that every intermediate observation is present. Missing adjustment fields or duplicate dividend records stop the calculation. Prices and distributions can be revised by the provider.
The model excludes fees, taxes, FX, reinvestment, spin-offs and other noncash distributions. It cannot reconcile a brokerage statement or prove that PG is defensive, undervalued or suitable for a portfolio. A provider company profile is informational and is not a live executable quote.
