Suppose you find that prices of stocks before large dividend increases show on average consistently positive abnormal returns. is this a violation of the emh? yes no

No

Explanation:

EMH an acronym for Efficient market Hypothesis is a theory that security prices reflects all available information making it impossible to beat the market by taking undue advantages.

The information provided in the scenario is not detailed enough to give an investor the opportunity to earn abnormal returns .It just show that good performance leads to higher dividends as better performing stocks pay higher dividends

NO

Explanation:

The efficient market hypothesis (EMH) theory states that the market price of securities reflects all the public information regarding them, e.g. expected earnings, etc. One of the basic premises of EMH is that it is useless for investors to pick individual stocks to try to obtain higher than normal results. It places a lot of emphasis on the market as a whole, instead of individual stocks.

If the prices of stocks vary a lot just before dividends increase, it actually reflects and supports EMH. Since the market expects an increase in dividends, the price of stocks will rise, but generally stock prices will rise too much and must then be adjusted to reflect the real value. Also, in the short run prices will appear to be varying randomly, but that happens because the inflow of information is not constant and expectations will vary. But on the long run, the prices will adjust to the correct information.
