Why read this guide: by the end you will know where to find trustworthy cmcsa stock price quotes, how to interpret common quote fields, what corporate and market factors typically move the stock, and how to access historic CMCSA data for analysis.

Ticker symbol and listing

• Ticker: CMCSA
• Exchange: Nasdaq (primary listing)
• Share class: Class A common stock (voting shares distinct from Class B in corporate filings)
• Identifiers: look for CMCSA in major data providers; ISIN and CUSIP codes appear in official filings and on Nasdaq/company investor pages
• Trading hours relevant to the cmcsa stock price:
  • Regular session: 09:30–16:00 ET (Nasdaq regular trading hours)
  • Pre-market and after-hours sessions exist and produce extended quotes and trades; prices displayed for extended hours are often labeled as pre-market/after-hours

When you check the cmcsa stock price, confirm whether the quote is from regular hours or extended hours and whether the feed is real-time or delayed.

Real-time quotes, delayed data, and data providers

Investors and traders can obtain cmcsa stock price information from many data providers. Key providers commonly used are:

• Yahoo Finance
• Google Finance
• Nasdaq (official listing pages and real-time feeds)
• TradingView (charting and community ideas)
• Robinhood (retail brokerage quotes)
• MarketWatch
• Morningstar

Differences to be aware of when watching the cmcsa stock price:

• Real-time vs delayed: some free websites display delayed quotes (commonly 15–20 minutes) for Nasdaq-listed names unless the user subscribes to a real-time feed. Nasdaq Basic and other exchange feeds may require a subscription for direct, guaranteed real-time data.
• Level of detail: brokers and paid vendors often provide Level 1 (best bid/ask and last trade) or Level 2 (market depth) data; public sites typically provide Level 1 and aggregated volume metrics.
• Aggregation and timestamping: different providers aggregate trades differently and timestamp quotes based on their servers; always verify the quote timestamp when precise timing matters.

When you compare the cmcsa stock price across providers, expect minor differences in bid/ask, last trade timestamp, and displayed volume when feeds are delayed or when extended-hours trades are included.

Common quote fields and meanings

When you view a cmcsa stock price quote, typical fields include:

• Last trade price: the most recent executed trade for CMCSA (may reflect extended-hours trades if so labeled).
• Change and percent change: movement versus the previous official close (absolute and percentage).
• Bid / Ask: the highest price a buyer is willing to pay (bid) and the lowest price a seller will accept (ask) at the time shown.
• Day's range: lowest and highest trade price for the current trading day.
• 52-week range: lowest and highest CMCSA prices over the past 52 weeks; useful for context on multi-month performance.
• Volume: number of shares traded in the current session.
• Average volume: average daily traded shares over a defined period (commonly 30 or 90 days); used to assess liquidity relative to current activity.
• Market capitalization: current price multiplied by shares outstanding; provides a size metric for CMCSA.
• Dividend yield: trailing or forward dividend yield based on recent dividend payments and the current cmcsa stock price.
• P/E ratio and EPS: valuation metrics (price-to-earnings and earnings per share) that affect how the cmcsa stock price is interpreted by value-focused investors.

Interpreting these fields for CMCSA requires context: a wide bid-ask spread or sharply higher short interest can increase volatility and influence how a given cmcsa stock price translates into trade execution expectations.

Key market metrics and summary statistics

Important metrics to monitor alongside the cmcsa stock price include:

• Market capitalization: indicates the overall market value of Comcast's publicly traded equity and helps compare CMCSA to peers.
• P/E ratio and forward P/E: commonly reported on finance pages and used to gauge relative valuation.
• EPS (trailing and forward): earnings per share affect valuation multiples and can move the cmcsa stock price around earnings releases.
• Dividend yield and payout: Comcast historically pays dividends; dividend announcements and changes influence income-seeking investors and the cmcsa stock price.
• Beta: a measure of CMCSA's sensitivity to broader market moves—higher beta generally means larger swings in the cmcsa stock price during market-wide moves.
• Shares outstanding and float: outstanding shares determine market cap; free float influences liquidity and the impact of large trades on the cmcsa stock price.

You can find these metrics on provider pages (Yahoo Finance, Google Finance, Nasdaq, Morningstar) and in Comcast's regulatory filings on SEC EDGAR and the company's investor relations resources.

Historical price performance

Historical measures commonly used for analyzing the cmcsa stock price:

• Daily, weekly, and monthly charts: visualize trends, volatility, and moving averages across time windows.
• 52-week high and low: quick view of recent extremes relative to current cmcsa stock price.
• Multi-year performance: shows how CMCSA performed through business cycles (important given Comcast’s mix of distribution and media assets).
• Total return: incorporates dividends into returns; total return can materially differ from price return alone over long windows.
• Split-adjusted data: historical cmcsa stock price series are commonly adjusted for stock splits and corporate actions to ensure apples-to-apples comparisons.

Comcast's investor relations provides archived historical prices and corporate actions that allow investors to reconstruct split-adjusted total return. Third-party vendors such as Morningstar, Nasdaq, and Refinitiv/LSEG provide downloadable historical price series as well.

Historical data sources and caveats

Primary sources for CMCSA historical prices and caveats:

• Comcast investor relations: official historical price lookup and corporate action notices (splits, dividends, spinoffs).
• Nasdaq: official exchange data, including historical trade and volume series.
• Refinitiv/LSEG, Morningstar: vendor-provided historical series and total-return calculations.
• Yahoo Finance and Google Finance: convenient downloadable CSVs of historical prices (often adjusted for splits and dividends).

Caveats:

• Timing and adjustments: different vendors may apply dividend and split adjustments differently; verify whether data is adjusted for dividends when calculating total return.
• Vendor delays: free providers sometimes apply delayed prices for Nasdaq-listed stocks; historical archives are generally complete but confirm the source when performing formal analysis.
• Corporate actions: spinoffs, special dividends, or reorganizations (for example, major asset dispositions or spinoffs) can make blind multi-year price comparisons misleading unless adjusted appropriately.

Trading statistics and liquidity

Liquidity and trading stats impact execution and price stability for the cmcsa stock price:

• Average daily volume: higher average volume generally means tighter spreads and easier execution for larger orders. Check the 30- and 90-day averages displayed on major finance pages.
• Intraday volume patterns: CMCSA commonly sees higher volume at market open and close, similar to many large-cap equities.
• Bid-ask spread: during normal conditions CMCSA typically exhibits narrow spreads, but spreads can widen in volatile markets or for extended-hours trading.
• Shares float and institutional ownership: a high institutional ownership percentage can increase trading volume but may also concentrate ownership, affecting directional moves in the cmcsa stock price.
• Short interest: the number of shares sold short can influence price dynamics, especially if short interest rises materially.

As of 2026-01-26, short interest details reported by Benzinga show that Comcast Corp had 61.14 million shares sold short, representing roughly 1.69% of float. Short interest had risen 14.19% since the prior report, and based on average trading volume it would take about 1.54 days to cover those short positions. This increase in short interest signals a rising bearish bet among some market participants, though short interest alone does not predict near-term direction for the cmcsa stock price.

Corporate events and actions that affect stock price

Corporate actions often move the cmcsa stock price or change its historical comparability:

• Dividends: announcements of dividend increases, decreases, or suspensions affect income investors and can shift the demand for CMCSA shares.
• Stock splits or reverse splits: divide or consolidate shares of record and affect the per-share cmcsa stock price while leaving market capitalization unchanged (subject to market reaction).
• Share buybacks: reduce shares outstanding and can increase the cmcsa stock price by boosting EPS and reducing float.
• Spinoffs and restructurings: major asset spinoffs (for example, proposed or completed separations of business units) change the company’s asset base and can materially affect the cmcsa stock price and valuation multiples.
• Mergers and acquisitions: strategic deals or sales of assets can create re-rating events for the stock.

When analyzing historical cmcsa stock price series, adjust for any of these events to preserve comparability. Comcast’s investor relations and SEC filings describe corporate actions and provide the official record.

Business fundamentals and valuation drivers

Understanding how underlying business performance drives the cmcsa stock price helps interpret moves beyond technical factors. Comcast’s main business segments include:

• Residential connectivity (Xfinity broadband and video): subscriber growth, ARPU (average revenue per user), and churn affect revenue stability and growth expectations tied to the cmcsa stock price.
• Business services: broadband and network services to enterprise clients; margin expansion or contraction here can move valuation.
• NBCUniversal and media assets: advertising revenue cycles, box office and streaming performance, and content costs influence investor sentiment toward CMCSA.
• Sky (international pay-TV and broadband; where applicable based on regional operations): international subscriber trends and currency effects impact consolidated results.
• Theme parks and experiential assets: these contribute cyclical revenue tied to travel and consumer spending.

Key valuation drivers for the cmcsa stock price therefore include broadband subscriber growth, advertising revenue trends (particularly for media businesses), streaming and content investments, cable cord-cutting rates, and capital allocation decisions such as dividends and buybacks.

Recent financial results and impact on price

Quarterly earnings releases and guidance updates are frequent catalysts for the cmcsa stock price. Typical market reactions occur around:

• Revenue beat/miss relative to consensus
• EPS beat/miss driven by operational performance or one-time items
• Changes to forward guidance or management commentary on subscriber trends, ad revenue, or content costs
• Major one-off items (e.g., impairment charges, gains from asset sales, litigation settlements) that shift reported EPS

Earnings cadence: Comcast generally reports quarterly results and provides guidance during earnings calls and press releases. For the most reliable information, consult Comcast’s investor relations and SEC filings for earnings releases, 10-Qs and 10-Ks.

Note: when the market receives unexpected guidance cuts or upgrades, the cmcsa stock price can gap down or up significantly at the open following the announcement.

Analyst coverage and market sentiment

Analysts publish ratings and price targets that can influence the cmcsa stock price in the short and medium term. Key points:

• Consensus ratings and price targets: aggregated by data vendors and fiscal news providers; helpful for gauging market sentiment.
• Institutional holdings: large institutional flows into or out of CMCSA can move the price due to block trading and rebalancing.
• News flow: corporate announcements (dividend changes, spinoff news, leadership changes) and industry news (ad market softness, regulation) can shift sentiment quickly.

As with any stock, analyst views are opinions and should be considered alongside primary source data. Data providers report consensus targets and rating distributions for CMCSA—check those pages for the latest snapshot.

Factors and risks affecting CMCSA stock price

Key risk factors that materially affect the cmcsa stock price include:

• Technology and competition: streaming platforms, regional broadband competitors, and alternative content distribution models can pressure revenue or require heavy investment.
• Advertising cycles: media-ad exposed segments are sensitive to macroeconomic cycles and advertiser budgets.
• Regulatory risk: telecom and media regulations (net neutrality debates, content regulations, merger approvals) can influence strategy and valuation.
• Macro conditions: interest rates, consumer spending, and capital markets conditions affect capital allocation and investor appetite for CMCSA.
• Execution risk: subscriber retention, content cost management, and integration of strategic assets all affect realized results versus expectations.

Monitor SEC filings, company presentations, and trusted market news for disclosures on risks and management’s mitigation plans.
