If you know of any lawyers who do corporate merger work and are willing to discuss their business, this can be quite profitable. All you need is the name of the company about to be bought out, and get it before the announcement. This is pretty much the only "sure-fire" way of getting an insider tip to work, as sometimes the stock doesn't do what you would think when it's inner-company stuff. Just drop the stock at the merger price as soon as the offer is announced, and voila - free money!I would pay for this information, personally, but this is the only stuff I would actually pay for.
