fyi regarding the OSUR short trade:

Meanwhile, OraSure (OSUR:$9.10,00$-0.75,00-7.61%) is halted as the FDA advisory panel meets today to decide whether or not to vote in favor of its OraQuick In-Home HIV Test.The OraQuick In-Home HIV Test would be the first Home HIV test that is sold without a prescription.Market chatter has the FDA panel decision coming in later today with the stock opening back up for trading in tonight’s after-hours session.

earnings and news induced gaps and trading halts on stocks are always part of the game.  these things can go either way but one thing that is almost a certainty is that the stock will either open much higher or much lower once the trading halt is lifted.  the recent ARNA long popped up over 300% on news shortly after being stopped out the other day (including my shares).  just one more reason always make sure that your position sizing is always commensurate with you risk tolerance.
