NEW YORK ( TheStreet) -- Anytime I come across something that I think is too good to be true, I get nervous. The skeptic in me always seeks to find fault in whatever it is that happens to be the fascination of the day. On Wall Street, that term is called "due diligence."Although it is often talked about, not everyone appreciates enough the value of sound fundamental research that often leads to the somewhat solitary state of "not believing the hype." This was the case last week with Facebook ( FB) -- whose hype-filled IPO was full of drama and intrigue leading into the closing bell as it was clear to the entire market that it required a concerted effort from Nasdaq and the company's underwriters to close at $38 in order "to save some face."
