Price effects during dividend periods: alpha, cash flow and tax

We investigate the pervasive but misunderstood price effects of stocks in the period surrounding their dividend payments. Known as “dividend run up” (DRU), we observe a positive excess return from tilting towards dividend paying stocks in the month (or slightly longer) prior to the ex-date. There are two separate effects to consider: the cum-dividend price run up, and the ex-dividend price drop off.

Note that this effect is often thought to be a tax effect specific to Australia. Investors who hold stocks that pay franked dividends in theory “go on strike” from selling for 45 days surrounding the dividend ex-date, in order to capture the franking credit along with the cash dividend. This creates price pressure which drives up prices. While this supposition appears to be at least partly true, the same effect manifests itself in unfranked dividend payers in Australia, and in many other markets around the world. There is more to this than just maximising dividends and franking. Note that this paper looks only at Australian stocks. Later work will extend it to other markets around the world.
