How to Find Historical Stock Prices for Specific Dates
Historical stock prices for specific dates are the recorded market quotes tied to a calendar day: opening and closing quotes, intraday highs and lows, and settlement values that reflect trading on an exchange. This piece explains why people pull date-by-date prices, how different price series are reported, where to get reliable records, how to ask for a single date or a range, and the practical trade-offs when using downloaded data for analysis, tax reporting, or audits.
Why people look up prices by date
Investors and professionals use date-specific quotes for many reasons. An investor checking how a position behaved during a market event will compare the closing numbers before and after that date. An accountant or tax preparer needs a verified quote to calculate gains for a sale recorded on a certain day. Analysts reconstruct returns for a backtest and need consistent daily values. Each use emphasizes a slightly different piece of the record: some need the last traded price, others the official settlement, and some want intraday details like the high or low.
Types of historical price series and what they mean
Price series come in at least two common forms. One reports raw trade and quote levels without adjusting for corporate actions; call this the unadjusted sequence. The other reports numbers that account for stock splits and distributions so past prices are scaled to be comparable with current prices; call this the adjusted series. Adjusted values are useful when measuring percent returns over time, while unadjusted values are needed to match exact trade records for a given date.
Common data sources and how to access them
Reliable sources fall into a few categories: official exchange archives, brokerage or custody platform histories, commercial data vendors, and public open-data sites. Exchange archives are authoritative for settlement values and timestamps. Broker platforms often show the same historical quotes but tied to account reporting. Commercial vendors sell bulk access or application programming interfaces, often with added tools for correcting corporate events. Open sites may provide free downloads but can vary in coverage and update cadence.
| Source type | Typical coverage | Common formats | Access method | Freshness |
|---|---|---|---|---|
| Exchange archives | Complete for listed symbols | CSV, daily reports | Download or paid feed | End-of-day official |
| Brokerage statements | Client account symbols | PDF, CSV | Account portal | Daily or monthly |
| Commercial vendors | Broad market coverage | CSV, API, database | Subscription, API keys | Real-time to delayed |
| Open data sites | Popular symbols, gaps possible | CSV, web | Free download | Varies |
How to request prices for a specific date or range
For a single date, identify whether you need the official close, the last trade, or a settlement value reported by the exchange. When using a web chart, set the calendar to the date and check the reported field label. When using an API, ask for the date in ISO format and specify the field name for that date, for example the closing figure. For a range, request start and end dates and decide whether weekends and market holidays should appear as blank rows, interpolated values, or omitted entirely. Many tools let you request business-day-only data to simplify time-series calculations.
Formatting and download options
Most services offer at least one of three formats: comma-separated values for spreadsheets, an API for programmatic access, and chart images for quick visual checks. CSV files are the simplest for audits and tax records because they record a date column and clear numeric fields. APIs return structured data that can be pulled directly into analysis software and updated automatically. Chart exports show trends but are poor for exact record-keeping. Choose formats that match your workflow: CSV for ledgers, an API for automated systems, and charts for illustration.
Common data quality issues to watch for
Typical errors include missing days, mismatched timezone stamps, incorrect application of corporate actions, and off-by-one date shifts when data providers use different market calendars. A symbol can change when a company re-tickers or moves exchanges; old records may be split across identifiers. Dividend payments and splits may be reflected in adjusted values but not in raw numbers, which affects return calculations. Always check the provider’s note on how adjustments were applied and whether reported prices are trade-level or settlement figures.
Practical constraints and trade-offs
When choosing a source, weigh coverage against cost and legal limits. Exchange archives are authoritative but may charge for downloads. Free sites offer easy access but sometimes omit less liquid instruments or overnight trades. Corporate actions can change historical series; deciding whether to use adjusted numbers changes the outcome of a percent-return calculation. Timezone settings matter for international symbols because a quote timestamp might show a different calendar date in local accounting systems. Market holidays can create gaps that need to be handled for continuous analyses. Licensing terms can restrict redistribution of downloaded data, so check usage rights if you plan to share or publish figures.
Use cases that shape the data choice
For tax and audit needs, choose a source that provides a verifiable timestamp and a format accepted by auditors, like a CSV or exchange report. For performance analysis, use adjusted values that account for splits and distributions to avoid overstating past prices. For trade reconstruction, use raw trade records or broker statements to match executed fills. For research or model development, a commercial API with broad coverage and a clear documentation of adjustment methods is often the most efficient path.

Where to find historical stock prices sources
To move from exploration to verification, compare a small sample from multiple sources for the same date and symbol. Look for consistent values for the field you care about, and read the provider’s notes on corporate-action handling and timestamps. For regular work, choose a format and access method that fit your tools: CSV for manual checks, an API for automation. Keep in mind the trade-offs between cost, coverage, and legal use.
