The stock dropped by the dividend on ex-date. Is something wrong?

Nothing is wrong. On the ex-dividend date a stock usually opens lower by about the dividend, because that cash is leaving the company. Your option prices already expected it.

Why the stock dropped

On the Ex-dividend date, the dividend stops coming with the shares. Anyone who buys from that day on won't get this payment. So the stock usually opens lower by about the dividend amount.

Think of a company as a jar of cash and other stuff. When it pays a dividend, some cash leaves the jar and goes to shareholders. The jar is now worth a little less. The price follows.

If you owned the shares before the ex-date, the dividend is yours. You lost $0.50 a share in price and you're owed $0.50 a share in cash. That's a swap, not a loss.

The numbers (an illustration, not a trade idea)

You own 100 shares of a made-up stock, XYZ, with a cost of $48. It trades at $50. You sold a 30-day $52 call for $0.90 and collected $90. A $0.50 dividend goes ex during the trade.

On the ex-date, XYZ opens at $49.50. Your screen shows the shares down $50. But you're owed $50 in dividends, paid on the pay date a few weeks later.

The call barely moves on the drop. Its price already had the dividend built in, so the market wasn't surprised.

Here's every outcome at expiry, with the dividend included:

What it does to your covered call

Three things are worth knowing.

1. The drop was already priced in. Option prices use the expected dividend. Before a known dividend, calls are a bit cheaper and puts a bit dearer. So the drop doesn't hand you a surprise gain on the call.
2. You keep the dividend if you still own the shares at the ex-date. The call doesn't change that. Being short a call isn't the same as having sold the shares.
3. The real risk is the day before. If your call is in the money and has little time value left, the buyer may exercise early to grab the dividend. Then your shares leave before the ex-date, and you don't get paid. See the last row.

Our guide on early assignment before a dividend explains how buyers decide, in plain numbers.

What it does to a short put

If you sold a Put option instead, the drop moves the put a little closer to your strike. That's also priced in. Put sellers on dividend stocks collect a slightly bigger premium for exactly this reason.

You don't get the dividend on a put, because you don't own shares yet. If you're assigned after the ex-date, you buy shares that have already paid it.

When a drop on ex-date is something else

Sometimes the stock falls far more than the dividend on the same day. That's not the dividend. It's news, the market, or both, landing on the same morning.

Quick check:

• Drop ≈ the dividend? Normal. Do nothing.
• Drop is several times the dividend? Look for news. Treat it like any other fall: check your give-up price and the business.
• The dividend itself was cut? That's a business change. Read when to stop wheeling a stock.

It's easy to blame the dividend for a move it didn't cause. Compare the size first.

How to plan around dividends next time

• Know the ex-date before you sell the call. It's on the company's investor page or your broker's quote screen.
• Decide if you want the dividend. If you do, pick a strike less likely to be in the money before the ex-date, or an expiry that ends before it.
• Check the call's time value the day before. If it's smaller than the dividend and the call is in the money, early assignment is a real chance.
• Log the dividend in your journal. It lowers your real cost, just like a premium does.
