Earnings Implied move

Hey everyone, so I found something interesting that is not making much sense and hope if you can clarify it. Expected 1 day move is = IV*sqrt(1/365)*Stock Price. On liquid stocks this calculation works beautifully. But on illiquid stocks, things get funky. Let's look at CXO, earnings are after the bell. The expected 1 day move is 5.67. BUT the IV for the straddle is 32%.... so we have .32*sqrt(1/365)*155.50 = 2.60. Obviosuly the market will not give me free bees. So WTF
 
An eyeballed mistake on my part:
The traditional formula uses 1/365 for time, but in practice, I've seen (and used) 1/252, and *generally* gotten better results.

The results here would be about 3.03 against your computed 2.60 -- a 20%+ difference.
But that won't get anybody to 5.67.....

But, having an equation and one unknown.....
But I can't: it's 2pm, and I have a lot of work before 3pm.
FOMC tomorrow means I have no overnight available......
 
You are comparing two different things. One day expected move is different than straddle price based on 18 days

The straddle is 8.90 mid. After earnings the vol usually drops to ~27% meaning the straddle will be worth ~ 7.40....8.90 - 7.40 = 1.50 expected move tomorrow. No where near 5.7. Even if it dropped to 20% vol which it never has in the past 4 earnings, the straddle would be ~5.8. Meaning a 3.10 move tomorrow. If I look at my bloomberg screen it tells me that the average move over the last 8 quarters is 3.8% which would be equivalent to a 5.89 move. So this straddle is trading dirt cheap. Srinir can you look into this and correct me if I am wrong. It's a profitable play if I am right. Thanks
