The relatively mooted post (half-trading-day) July 3rd trading in MTSL is interesting.
The news, which, without a doubt, are terrific lead to a huge gap up in the morning on the third, followed by the usual post-open fading. However, since there was no closing trades and the market was closed on July 4th, the rally seems to have no legs this morning.
This probably tells you a lot about how fickle traders are.
BTW, I noticed with interest the peculiar coincidence of trading volume on July 2nd. As it was the case with VERA, it remarkable how "lucky" traders are, keeping on finding low volume shares and buying in with large positions precisely a day before good news are released. Almost as lucky as SAC, I guess.
