How far ahead do companies confirm their earnings dates?

It varies by company. Many announce the date a few weeks before the report, and some give less notice. Until the company posts it on its investor relations page or in a press release, the date on a calendar is a projection, usually based on when the same quarter was reported a year earlier.

Should you sell a stock before its earnings report?

Selling is one choice. Trimming is another. The deciding figure is the loss you would take if the stock opened sharply lower the morning after the report, measured against the whole portfolio. If that loss is more than you would accept, reduce the position while prices still move in small steps.

How to Filter an Earnings Calendar Down to the Stocks You Own

Q: How to Filter an Earnings Calendar Down to the Stocks You Own

Put your holdings and watchlist names into the calendar's watchlist or portfolio filter so only those companies show. Then check whether each date is confirmed or estimated, note whether the report comes before the open or after the close, and settle each position's size before the date arrives.

A full earnings calendar on a busy morning runs for pages. Most of the rows belong to companies you will never own. Scrolling it for your own tickers is how a report slips past. A filter solves that, and once it is set up and checked every week the calendar shrinks to the short list of names where a surprise in the numbers or the guidance would move your own money.

What goes on the list?

Every stock you hold, in every account. People forget the retirement account. They forget the small position bought on a whim and never checked again. Add the watchlist candidates you could buy within a month, because a report can reset the entry price you were waiting for, and then add any company whose results tend to move a stock you own, such as a large customer, a major supplier or a close competitor that reports first in the season.

Keep it to tickers. Nothing else is needed yet.

Which filter does your calendar have?

Broker platforms and market-data sites usually offer a watchlist filter, a portfolio filter, or both. The watchlist version shows reports only for tickers on a list you saved. The portfolio version reads your positions straight from the account, which means it stays current when you buy or sell, though it can’t show a stock you don’t own yet. If the platform allows both, use both; if it allows only a watchlist, build one list that holds your positions and your candidates together and update it every time you trade.

Then widen the view. A daily view hides next Tuesday.

Is that date confirmed or estimated?

Look at the marker beside each date. Confirmed means the company has announced it. Estimated means someone projected it. The usual basis is the date of the same quarter’s report a year earlier. The company may pick a different day, sometimes a week or more away, so a week that looks clean on the calendar today can fill up with reports once the confirmations arrive.

Before the open or after the close?

The timing column decides which session carries the move. A report before the open reprices the stock at that morning’s open. No regular session sits between the release and the first print. A report after the close arrives once regular trading has ended, so the first reaction happens in after-hours trading, where volume is thin and spreads are wide, and the first price with full liquidity behind it is the next morning’s open. A stop order sitting at the broker offers little protection through that gap. The first trade can print well past your stop.

What else lands in the same week?

Mark option expirations and ex-dividend dates on the same sheet. Say you hold calls on a stock that reports two days before they expire. The report then hits contracts with almost no time value left, and a covered call you sold can be assigned if the stock jumps through the strike. Ex-dividend dates matter if you plan to sell around the report. To collect the payment, you must own the shares before the ex-dividend date.

How much of the portfolio reprices at once?

This is the sum the filtered view makes possible. Take a hypothetical $60,000 portfolio. Three of its stocks report in the same week. They are worth $8,000, $6,000 and $10,000.

Four dollars in every ten reprice within a few days. None of the three reports has to go badly for that to matter, since a week with 40% of the money exposed to overnight gaps can move the account further than your usual stops were built to allow, and the stops themselves can’t be counted on at the open.

Size it before the date

Sizing belongs to the days before the report. The price still moves in small steps then. For each name, pick a gap you’d call plausible and work the loss if it goes against you, using 10% as the example.

Is 4% of the account on one bad week too much? Then trim before the date. The earnings gap loss calculator runs the same sum for any position and any gap. An earnings gap can be larger than the options market implied. Reading that estimate off the chain is covered in the earnings implied move, and it gives you a second number to size against, one the market itself is paying for, which helps when your own guess at a plausible gap is little more than a round figure picked because it felt about right.

The case for sizing every held position by its gap is made in holding a stock through earnings. More on reading the reports themselves sits in the earnings hub.

An unfiltered calendar is mostly other people’s news.
