Is this data available, and if so is it legal to publish it?

The job of this hypothetical business is to find these things out, and publish them. Answering this question yourself is therefore part of the work required to create such a business, but the short answer is that it's available if you can find it, and by and large, if it's true it's legal to publish (but beware of Swiss laws on business secrets).

How to profit from doing this - doesn't spring to mind immediately.

1. Invest in what you're recommending.
2. Publish a free web site and offer a paid newsletter.
3. When you have built up enough reputation that people with serious money start asking you for advice, sell it to them.
4. Become an investment company and invest other people's money for them.
