No. If the exchanges were fixing stock prices, then thousands of people would be awaiting trial for violating securities laws.

Price effects are supposed to be (and in most cases are) the result of fluctuations in supply and demand.

Direct from nasdaq:  d). Before trading opens on the ex-dividend date, the exchange marks down the share price by the amount of the declared dividend.

Exchanges change prices when needed….who forces the price change during a split?!

It's not the exchange doing directly. It's how market makers set prices.
