MAC is trading 30.30 with IV30™ up 6%. The company has earnings in two days (2/11/10 BMO). The company has traded over 5,000 options today in the first two hours on total daily average option volume of just 877. Further, 4,900+ puts have traded for a 1:19 callut ratio. The largest trades have been the Sep 25 puts; ~4,700+ have been purchased so far today. The Company Tab and day's biggest trades snapshots are included in the article. The Options Tab snapshot is also included in the article. A couple of things to note: (1) Sep vol (49) is well below all other months which range 53-61. (2) The largest OI on any line is about 2,000. In just two hours ~4,700 open interest has been purchased in Sep 25 puts. Finally, the Skew tab snapshot is included in the article. You can see that not only is the Sep month (blue line) below all others (as we saw in the Options Tab), but also, the downside skew for just that line is tilted downward. The circle on the skew tab indicates the Sep 25 puts - see how much lower vol it is relative to the other 25 level puts (directly above it). Note that MAC has earnings in a couple of days.
