The news seems to be a takeover rumor. With the rumor comes a bend in the skew. You can see the CMC skew today and the SCHN skew (a "peer" with similar market cap). Click either image to enlarge.
Red - Front month
Yellow - Second month
Green - Third month
Blue - Fourth month
Note the distinct upside bend to the CMC skew in the front month (red) as these options are bid up on the rumor. The second month (yellow) is also relatively flat to a standard skew. SCHN follows a more standard skew. For a full run down on why option skew exists you can read the blog HERE.
This is trade analysis, not a recommendation.
