ironic, since you can't get shares to short. perhaps this will cause some price movement since you won't be able to reshort.
//The latest sign: ProShares Ultra VIX Short-Term Futures ETF (UVXY). is down by nearly 11% on the session. A few minutes after the Fed’s latest statement, NYSE Arca enacted a short-sale restriction on this leveraged volatility trading fund.//
That was yesterday. Any 10% down move triggers circuit breakers by SEC rules(209), and stock can't be shorted 'till next session. That's over now, but there are no shares to short anyway for me. Gotta go with VXX.
