Labor Day Markets Are Closed. Your Theta Isn’t.
· 3 min read
No bell rang this morning. No SPY tape, no QQQ tape, nothing to watch. Markets and the options exchanges are closed today for Labor Day. I still checked my phone twice out of habit before I remembered that.
But here’s the part that trips people up every single Labor Day: your open option positions don’t get a day off just because the exchange does. Time value doesn’t care whether there’s a trading session behind it. An option priced with 10 days to expiration on Friday wakes up Tuesday morning priced with 9 days to expiration. That calendar day still got subtracted. Theta decay is a function of time passing, not volume printing.
Why this actually matters if you’re holding through today
If you’ve got anything short-dated open — a weekly you sold, a spread you’re riding into next week’s expiration — you lost a day of extrinsic value with zero opportunity to react to it. No chance to roll, no chance to close, no chance to see the price move that would’ve told you whether to adjust. The clock ran, the market didn’t. That asymmetry is the whole lesson of a holiday Monday: theta is always on, price action isn’t.
It’s a small thing on any single day. It compounds into something real if you’re the type who forgets three-day weekends exist and gets surprised Tuesday morning that your position is worth less than you left it.
Friday’s close, for reference
Last session was Friday, September 4 — jobs report day. SPY closed at $770.19, down 0.39% from Thursday’s $773.17. QQQ closed at $718.96, up 0.18% from Thursday’s $717.67. Small moves in both, nothing that tells a clean story on its own. That’s the tape we’re picking back up from tomorrow.
What actually matters this week
Tuesday and Wednesday are quiet. No major scheduled data on the calendar for either day, so I’m not expecting much to move on its own weight. That’s typically when I do less, not more — a quiet setup week is not the week to force a trade because the screen is boring.
Thursday, September 10, brings PPI. Friday, September 11, brings CPI. Both land in the same week, both land right before the Fed’s September 15-16 meeting, and Fed officials are already in their pre-meeting communications blackout — no speeches, no interviews, no hints from anyone at the podium between now and the decision. That means CPI on Friday is going to be read by everyone as close to the last real data point the market gets before the Fed acts, without a single Fed voice around to contextualize it either way.
I’m not going to sit here and guess what either print says. I don’t have the numbers and neither does anyone posting confident forecasts right now. What I do know is how implied volatility tends to behave into a week like this: it builds. Slowly Tuesday and Wednesday, more noticeably Wednesday into Thursday, and then it usually gets its sharpest bid right before Friday’s CPI print, especially with the Fed blackout removing any other source of information for the market to lean on. Options premium tends to price in that uncertainty before the number ever hits the tape — which is exactly why holding short-dated premium into a week like this needs more attention than a normal week, not less.
What I’m doing with it
Nothing dramatic today, because there’s nothing to do today. I’m watching how premium builds through Tuesday and Wednesday to get a read on where the market’s actually nervous, and I’m treating Thursday and Friday as the two days this week where I want to be paying attention, not on autopilot. Six years in, the mistake I made most often in year one wasn’t misreading a number — it was not respecting that the days leading into a number matter as much as the number itself.
Day 214 of not placing a single manual order. Alertsify handles the execution side; my job this week is just to not get in its way during the two days that count.
