In America, dividend payouts are really low for most companies. And companies that pay dividends do it to court specific types of shareholders. If they are cutting the dividend it means they are burned all their margin of safety on their earnings and now have to sacrifice their core shareholders. It shores up their finances the way cutting back on alcohol improves the financial situation for an unemployed person. It helps but he's got bigger problems than a few beers.
That may all be well and good. And people know this. And people see all this happening. That is why, before the dividend cut, the stock price will be way, way down. At the time of the dividend cut, or really the announcement of the dividend cut, all the bad news will essentially be out and reflected in the stock price. Which is why the theory is that it is a good time to buy. You are playing checkers with your statement of the facts. We dividend cut buyers are playing 4d chess based on what people will be doing based on those facts.
