Right. But i was especially wondering whether just the people that post (or read) here would be likely to have that much influence on the SP? I have no idea whether that's a reasonable supposition, because i don't know the logistics involved in moving an SP like this one, and i would have thought that there aren't enough of us here to have that kind of effect .. unless some are trading much larger blocks than most of the trades which i see moving the SP. Most of those trades look fairly small, even by my low-volume standards.
