[reply to quantumdot]: You need to call the company and ask for the data. If you call them and they do not disclose, and you're certain that they disclosed more to another party, then you have a beef. But if you've not called and asked, you have no beef.
This is an erroneous interpretation of Reg FD.
The onus of Reg FD is on the company to not furnish selective disclosure to investors in the first place. Under your interpretation of the regulation, investors would need to be in constant communication with a company to assure that they were getting the full set of material information that had been furnished to other investors, which is clearly absurd from a practical standpoint.
