Looking up historical stock prices is easiest when you start with the right identifier (ticker symbol), choose the exact market you need (NYSE, Nasdaq, etc.), and then pull price data for a specific date range. Most investors rely on three common sources: brokerage platforms, market data websites, and official exchange feeds. The best choice depends on whether you need quick context (charts and adjusted prices) or downloadable data for analysis.
Many companies share similar names, and tickers can change after mergers or rebrands. Verify the company name, ticker, and listing exchange first to avoid pulling the wrong security. If you’re researching older periods, check whether the ticker has historical changes that affect older quotes.
Historical pages often show Open, High, Low, Close, and Volume. Decide whether you need the “Close” or the “Adjusted Close,” which accounts for stock splits and dividends. For performance comparisons over time, adjusted prices are usually more useful; for raw trading history, unadjusted close can be the better fit.
Select daily data for most research, or weekly/monthly for long-term trend work. If you’re validating a specific event (earnings date, split, or market shock), pull a tight date window around that event and compare multiple sources for consistency.
When exporting to CSV, scan for missing dates (weekends/holidays are normal), suspicious jumps (often splits), and timezone or currency differences if the security trades internationally. Cross-check at least one day against another source to confirm accuracy.

Close is the last traded price for the session. Adjusted Close modifies that value to reflect corporate actions like splits and dividends, making long-term comparisons more accurate.
