Index CFD dividend adjustments: shorts gain nothing on ex-dividend day, the DAX has none

When a stock goes ex-dividend its price drops by about the dividend. Add up enough of those drops across an index and the index itself dips a little on that day, with no change in demand. Brokers handle this for index CFDs with a cash adjustment: longs are credited the amount and shorts are debited. The adjustment cancels the mechanical drop, so the day is neutral for both.

A worked example, with made up numbers. A US500 CFD pays $1 a point and you hold 2 lots. Constituents going ex-dividend that day pull the index down by 1.1 points. A long loses 1.1 x 2 = $2.20 on price and receives $2.20 as the adjustment. A short makes $2.20 on price and is debited $2.20. Neither side gains.

Whether an index gets adjusted depends on how it is built. The S&P 500, FTSE 100 and Nikkei 225 are price indices, so ex-dividend drops show up in them. The DAX 40 is a total return index, which reinvests dividends, so it does not fall on ex-dividend days and brokers have nothing to adjust.

For scale, a dividend yield of about 1.3% on an index at 6,800 is roughly 88 points a year, or around 0.35 points per trading day on average. The payments are not evenly spread, since many companies share similar ex-dividend dates.

MT5 has a dedicated deal type for dividends, though some brokers post the adjustment as a balance entry with a comment, so look for it in the history.

Many short index traders are surprised by the debit, thinking the price drop on ex-dividend day is free profit. Japanese and Hong Kong indices have concentrated dividend periods, so the adjustments can be large on certain days. Checking the broker's dividend calendar before holding Hang Seng or Nikkei CFDs over those dates avoids surprises.

Some brokers pay the credit on longs net of a withholding rate. Take 2 lots long and a 1.1 point adjustment: gross credit $2.20. At a 15% withholding rate the net credit is $1.87, while the price drop cost $2.20, so the day is -$0.33 for the long. Over a year of holding 2 lots through 88 points of dividends, the gross credit is $176, and withholding takes $26.40 of that. The rates and whether the broker applies one vary by index and account type. The contract specification or the broker's dividend policy page usually states it. For a trade held a day or two, it is noise, but for a position held for months it is part of the carrying cost.

Ex-dividend days can distort a chart reading even when your account is neutral. Suppose you are long US500 and your stop is 3 points below the entry. The index opens 1.1 points lower because of dividends, with no news, and now the stop is only 1.9 points away. Your cash adjustment arrives as a separate balance credit, not as a price move, so the stop is not compensated by it. For a trade planned with a tight stop, a known ex-dividend morning is a reason to check the gap, or to move the stop by the expected amount. The broker's calendar, or the index provider's published figures, tells you what size to expect.

Compare the dividend credit to financing. Suppose one lot of US500 is $6,800 of notional and the broker's all in financing charge on longs is 5.5% a year, which is my illustrative figure. That is 6,800 x 0.055 / 365 = $1.02 a day. The average dividend credit, from the 88 points a year earlier, is about $0.24 a calendar day for one lot. The net is a $0.78 daily cost for holding the long, and the dividend only offsets about a quarter of it. So a long held for weeks pays mostly financing, and the dividend line on the statement is a partial refund, not a bonus. Check the financing rate on the specification page for the index you trade.

You can check your broker's practice with a single stock CFD, where the numbers are clear. Find a company with an announced dividend, say $0.25 a share, and an ex-dividend date. Hold 100 shares of the CFD across that date. The price should open about 25 cents lower, which costs $25, and the account should show a credit of about $25 a day or two later, possibly less withholding. If the credit never appears, or appears at a different size, ask support to explain the policy before you rely on it for indices. A short position on the same date should show a $25 debit. Keep the check small, a few shares, since the aim is to see the mechanism and not to trade the dividend.
