What "Historical Stock Prices" Means
Historical prices are time-stamped records of market trades and quotes. Typical fields you will see include:
- Date — trading day for the record
- Open — price at market open or first trade of the day
- High — highest traded price during the session
- Low — lowest traded price during the session
- Close — official closing price (raw close)
- Adjusted Close (Adj Close) — close price adjusted for splits and dividend distributions
- Volume — number of shares traded that day
- Split Adjustment Factor — factor used to convert unadjusted series to adjusted series when splits occur
The key distinction for analysis is between the raw Close and Adjusted Close. Adj Close modifies historical closes to reflect corporate actions (e.g., stock splits and certain dividends) so that percentage returns computed across long time spans are meaningful. For total-return or dividend-adjusted studies, use adjusted prices together with dividend records.
Primary Data Sources
You can obtain con edison historical stock prices from multiple authoritative places. Each has tradeoffs in coverage, adjustment method, and licensing.
Official investor site
The company’s investor portal includes a Historical Price Lookup tool maintained by the issuer. This official source is useful to verify corporate-action details such as declared splits, ex-dividend dates, and the company’s own published adjusted figures.
As of 2026-01-21, per the Consolidated Edison investor site, the historical price lookup provides official adjusted close values and corporate-action records for date reconciliation.
Exchange and market-data providers
Exchange feeds and market-data vendors supply the raw trade and quote data that underlies public portals. When available, exchange-sourced data (including end-of-day files) is the primary reference for official quotes and official disclaimers.
Financial portals and aggregators
Third-party portals aggregate and present historical price series and often provide convenient download options:
- Yahoo Finance — daily history tables, adjusted-close columns, and CSV download tools; widely used for quick retrieval.
- MarketWatch — offers downloadable CSV files and daily series for mainstream U.S. stocks.
- Macrotrends — specializes in long-term adjusted charts and annual summaries useful for decade-scale views.
- Investing.com — daily tables and charts with filtering and download options.
- Nasdaq (historical quotes) — provides exchange-focused histories and downloadable files.
- StockAnalysis — daily historical tables with export features.
- Seeking Alpha — historical quotes, dividend data, and event notes.
- CompaniesMarketCap and other aggregators — concise price-history summaries and metrics.
Each provider may format adjustments differently; always check the adjustment methodology if precise return calculations are required.
Historical Performance and Milestones
Presenting historical performance for con edison historical stock prices can be done at multiple granularities: intraday, daily, monthly, annual, and multi-decade. Long-term views reveal steady dividend yields, utility-sector characteristics, and responses to regulatory or weather events.
Notable price milestones commonly referenced include all-time highs and lows, major drawdowns during broad market stress, and recovery periods after sector-specific shocks. When documenting these milestones, link dates to corporate earnings, regulatory rulings, severe weather events, dividend policy changes, or other verifiable announcements.
Market-moving events that historically influence con edison historical stock prices include earnings releases, rate-case outcomes from regulators, significant infrastructure or liability announcements, and major service interruptions caused by storms. For accurate context, cross-check price moves with the company’s press releases or official filings.
Adjustments, Corporate Actions, and Data Interpretation
Properly interpreting con edison historical stock prices requires understanding corporate actions:
- Stock splits: Splits change the share count and must be applied to past prices so that series remain comparable. The split adjustment factor tells you how to convert unadjusted historical prices.
- Cash dividends: Ordinary cash dividends do not change the share count but reduce the company’s market value on the ex-dividend date. Adjusted-close often accounts for dividends to show total-return-equivalent prices.
- Spin-offs or reorganizations: These actions can introduce discontinuities that require separate handling or special adjustments.
Adjusted Close is the standard for return calculations over time because it accounts for splits and common dividend adjustments. However, if your analysis requires exact trade-level replication (for example, corporate-tax or wash-sale-sensitive backtests), you may need to use daily raw close and apply dividend series explicitly.
How to Access and Download Historical Data
You can access con edison historical stock prices through several user workflows depending on technical skill and licensing needs.
Using the company investor portal
- Visit the investor relations section and open the Historical Price Lookup tool.
- Select the date range or preset period (e.g., last 5 years, 10 years) and request the table.
- Download or copy the table and record corporate-action notes (splits and dividends) for reconciliation.
As of 2026-01-21, per the Consolidated Edison investor site, the lookup tool includes a split adjustment factor column useful for adjusting local datasets.
Using finance websites
- On a portal like Yahoo Finance, search for the ticker and go to the "Historical Data" tab.
- Choose the frequency (daily, weekly, monthly), pick a date range, and select "Download CSV."
- MarketWatch, Nasdaq, Investing.com, and StockAnalysis follow similar flows and typically provide CSV exports.
Programmatic access and APIs
For automated workflows, use:
- Public data endpoints and CSV exports offered by portals (mind usage limits and terms of service).
- Third-party APIs that provide historical price feeds (some free tiers have delays; paid tiers provide higher accuracy and licensing).
- Direct exchange or market-data vendor feeds for institutional-grade, real-time or near-real-time data (usually subject to subscription and redistribution rules).
When using APIs, always respect provider terms and check whether data is delayed (common for free endpoints) or real-time (usually paid).
Common Uses of Historical Price Data
Analysts and investors use con edison historical stock prices for:
- Performance analysis and benchmarking over chosen horizons
- Dividend-adjusted or total-return backtesting to evaluate long-term strategies
- Technical analysis using moving averages, RSI, MACD, and candlestick patterns
- Risk and volatility studies (standard deviation, drawdown analysis)
- Academic research and regulatory or sector studies
- Reconciliation and audit of trading or accounting records
For dividend-focused backtests, combine adjusted prices with a dividend series or use Adjusted Close if the provider’s adjustments match your required assumptions.
Data Quality, Limitations and Best Practices
Data consumers should be aware of typical limitations:
- Provider differences: Not all providers apply the same methodology for adjustments; small differences can compound over long horizons.
- Time delays: Public feeds often have a delay (e.g., 15 minutes) unless you subscribe to real-time data.
- Missing data: Holidays, corporate-action processing, and low-liquidity periods can cause missing rows or rounding differences.
- Timezones and conventions: Ensure your analysis aligns dates to the exchange’s local calendar and settlement rules.
- Licensing and redistribution: Some providers restrict downloading, commercial use, or redistribution. Review terms before using the data in a product.
Best practices:
- Cross-check prices and corporate actions against the company’s investor site and official filings for critical work.
- Use Adjusted Close for return analysis unless you have a strong reason to compute adjustments yourself.
- Keep a separate corporate-action ledger (splits, dividends, spin-offs) and log exactly how adjustments were applied.
- Document data sources and download timestamps to ensure reproducibility.
