Assassination.

Are you serious?

Of course he isn't. Nobody makes money in assassination these days, the market is oversold.

Thank you for the response!

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).

That makes a lot of sense, it would be hard to have a service that clarifies and presents already available material be illegal somehow. Defamation laws in Ireland are pretty stupid though.

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

Well beyond my (current) knowledge and abilities, but seems a solid plan.

Ethical investment.

Will investigate this further when I have more time.

Are you serious?

Not really. Only a tiny bit at most. I would not like to publish damning material on a very powerful corporation, but I guess one could focus on publishing positive material on good companies instead, if that was a concern.
