I am strangely reminded of an academic paper that came out, shortly before the (first) dot-com bubble popped, reporting that even after controlling for all sorts of other factors, companies saw their stock value go up after appending ".com" to their names.

Also, of VA Linux, which went public with the ticker symbol LNUX, decided they didn't want to be distributing Linux hardware after all, and changed their ticker symbol to, umm, something I don't remember. (Disclaimer: I used to own stock in LNUX.)
