Everyday the public German TV shows a couple of minutes how the stock market did, despite probably less than 5% of the population actually own stocks represented in the DAX. And of course that kind of information wouldn't be good to make investment decisions.

Given that most days are rather randomly on the stock market, and not determined by the one big news, I don't see a great newsworthyness in the stock market. In times like the current crisis, it might be newsworthy however, but you end up with one number (change of the index) and a gazillion possible explainations, why it moved now that way. For measuring the healthyness of the overall economy there are plenty of other numbers like GDP growth, unemployment etc.
On public TV, instead of stock market news, they should have a little segment, where economy is explained (e.g. how comes the money into the system, how is it prevented, that a bank simply adds a couple of zeros behind its cyber money, what are derivatives, or more controversal issues, and chage the guest experts every day).
