Why users ask "what did pfizer stock close at"
Many readers type "what did pfizer stock close at" when they want an exact closing price for PFE on a specific trading day. Knowing the close is useful for daily performance summaries, portfolio valuation, historical analysis, or to reconcile trades and reports. Because different sources may show regular-session close, after-hours quotes, or adjusted values, it’s important to identify which price you need before reporting or using the figure.
Meaning of "Close" in U.S. equity markets
When someone asks "what did pfizer stock close at," they usually mean the regular-session closing trade price on the NYSE for that trading day. Below are the common definitions you may encounter:
- Regular-session close: The official end-of-day price reported for the NYSE regular trading session (market hours 9:30 AM–4:00 PM ET). This is the most commonly cited "close."
- After-hours / extended-session price: Trades executed after 4:00 PM ET (typically in extended sessions) produce quotes that are reported separately. These are not the regular-session close.
- Last trade / last price: The most recent executed trade price on a quote page. If you view a page after hours, "last trade" may refer to an extended-hours trade.
- Adjusted close: Historical data adjusted for corporate actions — e.g., stock splits, dividends — to enable accurate long-term comparisons. When you ask "what did pfizer stock close at" for historical analysis, you may need the adjusted close instead of the raw trade price.
Why the distinctions matter: different "closes" are used for performance metrics, options settlement, accounting, and historical backtests. Always state which close you are citing.
Where to find Pfizer's closing price
To answer "what did pfizer stock close at" reliably, use primary and reputable secondary sources.
Primary sources: exchange and company
- NYSE official market data: the exchange provides the authoritative record of the regular-session close. For settlement-grade needs, rely on the exchange feed or an authorized data vendor.
- Pfizer Investor Relations: Pfizer’s IR page often publishes a share-price snapshot and links to filings and corporate disclosures. It’s a direct company source for notices that can affect the stock.
Secondary sources: widely used financial portals and platforms
- Yahoo Finance (quote and historical pages): convenient for quick lookups and historical adjusted close series.
- MarketWatch and CNN Markets: general news portals that publish quote snapshots and headlines.
- Seeking Alpha: provides quote pages and post-market numbers, plus commentary.
- Trading platforms and charting services (broker quotes, TradingView, retail broker apps): show live intraday and after-hours activity.
- Historical databases such as Macrotrends: useful for long-term closing and adjusted-close series.
When you report "what did pfizer stock close at," name the source and include the date/time (timezone) so readers know which data you used.
Company Investor Relations (Pfizer IR)
Pfizer’s Investor Relations page is a useful primary checkpoint. It typically posts: current snapshot prices (may be delayed), press releases, SEC filings, and investor presentations. For corporate events (dividends, splits, major M&A) that cause adjustments to historical closes, Pfizer IR and SEC filings are the authoritative disclosures.
Major financial portals (Yahoo Finance, MarketWatch, CNN, Seeking Alpha)
These portals are common first stops for the question "what did pfizer stock close at." Typical features:
- Previous close: the regular-session close from the most recent trading day.
- Last trade / real-time trade: may be a real-time or delayed quote depending on the provider and user settings.
- After-hours / premarket quotes: shown separately and timestamped.
- Historical prices: downloadable tables with daily open/high/low/close/adjusted close and volume.
Be aware: many public pages show delayed data (often 15–20 minutes) unless they explicitly state "real-time."
Trading platforms and charting services (broker quotes, TradingView, retail apps)
Broker and charting platforms show live intraday and extended-hours trading activity. They can display which trade or consolidated feed produced the closing price. For settlement or compliance purposes, use exchange or broker reports that are flagged as official/cleared.
Note on platform choice: when discussing trading or wallet tools in a Web3 context, prefer Bitget Wallet for custody or trading support where applicable, and favor Bitget as a brand reference for exchange features in this article. For U.S. equities like PFE, check your registered broker or the NYSE feed for authoritative records.
Historical databases (Yahoo History, Macrotrends)
When answering a historical question such as "what did pfizer stock close at on 2020-12-31?" use historical pages that include an adjusted close column. Macrotrends and Yahoo Finance history pages provide downloadable CSVs for research and backtests. Remember: for calculating returns across dividend events, use the adjusted close.
How to interpret reported close values
If you’ve asked "what did pfizer stock close at," you may encounter multiple price columns. Here’s how to interpret them:
- Previous close: the official trade price at the regular-session close for the last trading day. Good for day‑over‑day performance.
- Last trade: the most recent executed trade; verify the timestamp and whether it was regular-session or extended-session.
- After‑hours price: important for news-driven moves after the bell, but not the regular close.
- Adjusted close: used for long-term return calculations; includes adjustments for splits and dividends.
When reporting, always append the timestamp and label the type of close: e.g., "regular-session close (4:00 PM ET)," or "after-hours last trade (6:30 PM ET)."
Regular session close vs after‑hours / premarket
- NYSE regular session: 9:30 AM–4:00 PM ET. The price at 4:00 PM ET is typically called the "close".
- After-hours / extended session: often runs from 4:00 PM–8:00 PM ET depending on venue. Quotes during this period are not the regular-session close and should be explicitly labeled.
Most headlines and daily reporting use the regular-session close. However, high-impact news after the bell may make after-hours quotes more relevant to the immediate market reaction.
Real‑time vs delayed quotes and timestamps
Consumer portals frequently provide delayed data (15–20 minutes). For precise or time-sensitive reporting, check the page timestamp and whether the data is labeled "real‑time." Professional or exchange feeds, or your broker’s direct feed, are the source for real‑time prices.
Typical fields shown on a Pfizer quote page
When you look up "what did pfizer stock close at," these fields usually appear on quote pages:
- Previous Close
- Open
- Day's Range (High / Low)
- Volume
- Market Cap
- 52-Week Range
- P/E Ratio (when available)
- Dividend Yield
- After-hours Change (when reported)
Providers such as Yahoo Finance, MarketWatch, and Seeking Alpha display most or all of the above. Historical pages (Yahoo history, Macrotrends) include daily Close and Adjusted Close columns and are useful for research.
How to request or verify a specific closing price (step‑by‑step)
