15:47 ET Breakdown into close being blamed on an institutional sell program
15:54 ET Trading floors abuzz with talk that sell program was errant
Market managing a minor bounce off lows of the session. Hearing talk that the sell program that took equities down late was supposed to be entered in dollar terms, but was apparently entered as shares. Obviously, we have no confirmation of this, but talk of it is going around. And, given bearish slant by most traders of late, it does not seem like a rumor put out in hopes of rescuing the market.
