What an Earnings Calendar Shows (and What It Doesn't)
A standard calendar gives the report date, a timing label, and consensus estimates for EPS and revenue. Google Finance shows upcoming reports by day and week with those estimates, and Investing.com adds prior results. A live version with report dates is at the Fintwit earnings calendar.
The calendar leaves out more than it shows. Estimates differ by source for the same quarter, and most rows do not flag whether a date is confirmed.
- Shows: report date, BMO or AMC window, consensus EPS and revenue.
- Shows: expected move, derived from at-the-money straddle prices expiring after the report (Market Chameleon).
- Does not show: one agreed consensus. Amazon Q3 EPS estimates run $1.96 (MarketBeat), $1.97 (TipRanks) and $2.01 (WallStreetZen).
- Does not show: an exact release time. The window is not a timestamp.
- Does not show: whether the company has confirmed the date.
Reading Before-Market vs After-Market Report Timing
BMO means before market open, so the stock typically reacts at the opening bell. AMC means after market close, so the first move happens in after-hours trading and carries into the next session. Both labels describe windows, not exact release times.
Some sites narrow the window. StockAlarm's blog notes that Earnings Whispers predicts a specific time within BMO or AMC and attaches a confidence score.
Timing shapes the plan. An AMC report pushes the reaction to the next session, so set alerts for the next morning. Daylight saving changes shift ET-based times for readers outside the US, a detail many guides skip.
- Microsoft (MSFT): fiscal Q1 2027, after close, October 28; webcast 2:30 p.m. PT (5:30 p.m. ET).
- Alphabet (GOOGL, GOOG): Q3 2026, after close, October 28.
- Amazon (AMZN): Q3 2026, after close, October 29; call at 5:00 p.m. ET.
- AMD: Q3 2026, after close, November 3; consensus EPS $1.94 (Earnings Whispers).
Filtering the Week: Which Reports Actually Move Stocks
The week of October 23-29, 2026 lists 707 companies, so filtering comes first. Start with a short list ranked by market cap, expected move, and overlap with your portfolio or watchlist.
Among the six tickers in this post, NVIDIA carries the largest market value at $5.09 trillion. Walmart's 30-day return of 11.0% is the strongest of the group.
- Market cap: check which names are large enough to move index-level sentiment.
- Expected move: compare the calendar's percentage with the size of your position.
- Estimate spread: a wide gap between providers signals less agreement on the quarter.
- Watchlist overlap: begin with names you already track.
Turning Earnings Dates Into a Pre-Earnings Research Plan
Build a checklist five to ten days before each report. Microsoft announced its October 28 release on October 7, about three weeks ahead, which leaves time to prepare.
Use the calendar to pull the date for every name on your list, then log them in one place. The live earnings calendar shows the dates alongside each company.
- Confirm the date on the company's investor relations release, not only the calendar.
- Record consensus EPS with its source and date. Example: Amazon at $1.96 (MarketBeat) on the day you checked.
- Note the timing label and set alerts for the open (BMO) or the next session (AMC).
- Pull the expected move and compare it with your position size.
- Compare last quarter's guidance with the current consensus.
- Schedule a review within 24 hours of the print.
Where Investor Signals and AI Scores Fit Before a Print
Investor signals and AI scores add context before a print but are not a verdict. The figures below are Fintwit's live data: investment score out of 100, and the share of tracked investors on X who bought or sold in the last 30 days.
Three names trade above their median price target: Home Depot at $319.83 vs $278.00, Oracle at $126.16 vs $118.00, and Walmart at $119.89 vs $118.00. Before the print, check whether guidance supports a higher target or whether the target is stale.
- NVIDIA (NVDA): $210.96, score 84, 3.8% bought, 2.3% sold, median target $260.00.
- Broadcom (AVGO): $321.68, score 84, 1.5% bought, 0.4% sold, median target $445.00.
- Salesforce (CRM): $248.57, score 87, 0.0% bought, 0.4% sold, median target $310.00.
- Home Depot (HD): $319.83, score 61, 0.0% bought, 0.8% sold, bearish, median target $278.00.
- Oracle (ORCL): $126.16, score 63, high risk, 0.4% bought, 0.4% sold, bearish, median target $118.00.
- Walmart (WMT): $119.89, score 83, 0.0% bought, 0.4% sold, median target $118.00.
Common Mistakes: Trusting Unconfirmed or Stale Dates
Stale and unconfirmed dates cause the most avoidable errors. Amazon shows the problem: CME Elite Group says Amazon confirmed its October 29 date, while MarketBeat still lists it as an estimate.
- Check the company's IR release for every date before trading around it.
- Do not average consensus across sites. Note which source you used.
- Dates can shift. Most companies keep the expected date, but some report earlier, later, or at a different time.
- Implied moves are not forecasts, and implied volatility can fall after the announcement.
- Overnight gap risk is real: an AMC report can open the next day well away from the prior close.
- Micron and Nasdaq calendar dates were not verified here. Check their pages directly.
Frequently asked questions
- Where can I find a free earnings calendar? Market Chameleon, Google Finance and Investing.com are free options, and Yahoo Finance is also widely used. Verify the final date on the company's investor relations page.
- What do BMO and AMC mean in an earnings calendar? BMO means before market open and AMC means after market close. Both are timing windows, not exact times.
- How far in advance are earnings dates announced? Usually a few weeks ahead. Microsoft announced its October 28 report on October 7.
- Do earnings dates change after they are posted? They can. Most companies keep the expected date, but estimated dates are often replaced once the company confirms.
- Should I buy a stock right before its earnings report? That is a personal decision, not advice. Options-implied moves are not guaranteed limits, and overnight gap risk is real.
