Options expiry dates and major market events move prices. If you miss them, you can get caught off guard. The good news is you do not need to watch screens all day to stay informed.
Why Options Expiry Dates Actually Matter
Options are contracts that expire on a specific date. When a lot of contracts expire at the same time, trading volume spikes and prices can swing. This is called "options expiration" or "OPEX."
The biggest one happens every third Friday of the month. Four times a year, it lines up with index futures and stock futures expiring too. Traders call that "quadruple witching." Prices around those dates can move more than usual, even if you do not trade options yourself.
If you hold regular stocks or ETFs, knowing when these dates are helps you understand why your portfolio is suddenly moving.
Other Market Events Worth Tracking
Options expiry is just one thing on the calendar. Here are others that move markets regularly:
- Fed meeting dates (FOMC meetings, roughly every six weeks)
- CPI and jobs reports (monthly economic data the Fed watches closely)
- Earnings announcements for stocks you follow
- Index rebalancing dates (when big indexes like the S&P 500 add or drop stocks)
- Treasury auction dates (affects bond yields and sometimes stocks)
Missing any of these is easy. There are dozens every month. Most people either forget to check or only find out after prices have already moved.
The Problem With Checking Manually
You could bookmark a financial calendar and check it every morning. In practice, almost nobody keeps that habit for more than a week. Life gets busy.
You could set Google calendar reminders. But that means building the calendar yourself from scratch, and then keeping it updated when dates shift.
Neither approach sends you a clean summary with context, like "the next Fed meeting is July 30, and markets currently expect no rate change."
A Smarter Way: A Weekly Market Events Brief
The most useful thing is getting a short, plain-English brief each week that tells you what is coming up. Something like: here are the key dates this week, here is what analysts are watching, and here are the tickers most likely to move.
You can set this up with AIDular. It is a tool that searches the web on a schedule and emails you a clean, sourced report. You tell it what to track in plain English, pick how often, and it handles the rest.
Here is a prompt you can copy and paste to get started:
"Every Monday at 7am, send me a weekly market events brief. Include: options expiration dates this week, any Fed speakers or FOMC-related events, major economic data releases (CPI, jobs, GDP), and earnings announcements for Apple, Nvidia, Tesla, and Amazon. Add a short note on what traders are watching for each event. Include sources."
Adjust the tickers to match stocks you actually follow. AIDular will search for fresh information each week and email it to you. The Lite plan is free at aidular.com.
A Quick Routine That Actually Sticks
You do not need a complex system. Try this:
- Get a weekly brief every Monday (like the prompt above)
- Glance at it over coffee, takes about two minutes
- Note anything that affects stocks or sectors you care about
- Check back on those specific dates, not every day
That is it. No app to open, no website to remember. It lands in your inbox and you decide what to act on.
