Measure a historical price change
This calculator scales NVIDIA's daily closing-price series to a hypothetical USD investment. It uses FMP's full end-of-day price endpoint, rather than its separate dividend-adjusted series. The result is a price-return scenario, not a dividend-reinvestment total return or an actual account statement.
Check the dates and the price basis
- Choose a start and end date or a quick period. The amount must be positive and no more than $1 trillion; fractional units are permitted by the model.
- Calculate and read the actual observed dates and record count. The earliest and latest returned trading observations determine the result, even when a requested date was a weekend or unavailable.
- Inspect the first and last closes and compare their ratio. The simulated final value is investment × last close ÷ first close.
- Review the price chart for unusual changes or gaps. A chart built from provider observations does not prove complete daily coverage.
- Compare another asset only after aligning dates, currency, dividend treatment and costs. A price-only NVDA result is not directly comparable with a dividend-reinvested benchmark.
Reproduce the arithmetic
Synthetic example: if the first series value is $50 and the last is $60, a $1,000 allocation corresponds to 20 adjusted units and ends at $1,200. The price return is 20%. If those observations are 365 days apart, CAGR is (60/50)^(365.25/365) − 1, approximately 20.015%. These are illustrative inputs, not a claim about an actual NVDA period.
Historical prices adjusted for splits do not represent literal pre-split transaction prices. The scaled unit count is therefore a modeling convention. The calculator uses one close field throughout and does not mix adjusted and unadjusted fields when a value is missing.
Coverage and limitations
FMP documents a maximum of 5,000 records per request. This page makes one historical request, so it does not guarantee complete history from NVIDIA's IPO. Older-range responses can be cached on the server for 24 hours; requests ending today or later use a 15-minute cache. These intervals do not guarantee provider freshness. The separate company profile uses a five-minute cache and is not a historical snapshot for the selected end date.
Commissions, spread, taxes, dividend cash flows, slippage and currency conversion are excluded. Short holding periods can produce unusually large annualized numbers. Neither the return nor the chart establishes how much risk an investor could tolerate or what the stock will do next.
