The 7 calendar days before ex-dividend are a specific window where dividend-focused trades behave differently than the rest of the month. Some strategies work best in this window, some fall apart in it. This article defines the window, explains why price behaviour changes, and covers the one rule that usually matters: you must hold through the ex-date, not just buy before it.

What the 7-Day Window Actually Is

The ex-dividend date is the cutoff: own the stock at market close the day before ex-date, and the dividend is yours. The 7-day window is the run-up. In that stretch the stock often drifts up slightly in anticipation, then drops by roughly the dividend amount on ex-date as the payment "leaves" the share price.

T-7
Entry zone
Optional entry point for capture trades. Mild upward drift is common but not reliable. Best used as a shortlist, not a signal.
T-1
Last chance to qualify
Must own at close of T-1 (the day before ex-date) to receive the dividend. Buy later and you get the price drop without the payment.
T+0
Ex-date drop
Stock typically opens ~ dividend amount lower. This is mechanical, not a reaction. If you sell here you captured the dividend but also the drop — net zero before taxes.

The "Free Money" Trap

A common mistake: buy stock 2 days before ex-date, collect the dividend, sell the day after ex-date. Run the math: you paid $100, received a $1 dividend, sold at $99. You made $0, paid commissions, and owe tax on the dividend. The market is efficient about this; the payment shows up in the share price.

Real dividend capture only works when you either (a) have a thesis that the stock will recover the drop inside your holding window, or (b) hold long enough to benefit from the lower tax rate on qualified dividends.

The 7-day window is useful as a filter: it tells you which names are approaching payment and may deserve attention. It is not a standalone trade signal. Combine it with yield percentile, payout ratio, and your own thesis.

Where to See the Window in the App

The Dividend Data calendar highlights every holding and watchlist ticker whose ex-date falls within the next 7 days. Each row shows the declared amount, the current yield, and the qualification deadline — so you know the exact close-of-day where you need to own the stock to receive the payment.

Window = 7 days before ex-date
Must own at close of T-1 to qualify · price drops by payment on T+0
Use the window as a filter, not as a standalone trade signal
