No, $49.28 was rounded, there were many trades above and below. Have you spent the time to check what trades there were at $50.86? You got too much time on your hands, and in edit, you now can get GILD at $50.77 if you so desire.... Back in SINA here at $40.62 (and you can already get it at 40.61...oops, $40.50 <vbg>).
The "tension" on SINA is improving, now 2:1 in favor off buys.
