Given that in the space of 12 trading days SRX has gone from $13.33 to $15.45 and back to $14.00 (as I type), I suspect (given the size of trades and low volume) this is just UBS and others manipulating the trades for some profits both long and short - rather than any competitive drama or inside info on how performance is going.
