Why is theta so low on the 30 Feb Calls of MXIM? Is there a scan you can do to find such high delta/theta ratios?
I don't know what you're referring to--MXIM Feb 30C has an IV of 27%, a theta of -$3.30. This seems pretty reasonable to me. Delta and theta are not independent--the delta/theta ratio is not going to be a meaningful indicator. The "highest" ratio will always be ITM options which have a delta near 1.0 and a theta near 0.
yeah, im new to the greeks and IV, so this is all pretty fascinating to me. Could you give a quick, general idea of how IV effects the option?
In general, IV is the risk the market has priced into an option. For bio-tech companies about to hear from the FDA, the market may be pricing a 200% annual price move into the option because they have no idea what's going to happen. Just a quick google search turned over this page, which seems a reasonable intro to volatility: http://www.zaner.com/options/ov.asp
