Got this question in the comments earlier
So on the whole earnings-play thing…have you compared the relative merits of selling premium at different points in the expiration cycle…meaning, an earnings release with a couple days ’till expiration, vs. several weeks. Just wondering if over time they would tend to show different results…
I have never studied it, but have anecdotally experienced it. And my opinion is that an earnings report on Expiration tends to beget a larger move than one early in the cycle.
A move in motion on expiration week tends to stay in motion, be it because of earnings, the Fed, Bear Stearns (the stock) going to wallpaper, or whatever. Consider the “hand” concept. One side tends to get “hand” as Expiration gets closer and closer, and the other side must scramble. And when something is moving, option longs have the “hand”.
Now this dynamic plays out as options that seemed like rip-ups a day or two earlier get close to, or in, the money and cause a sudden squeeze on the option shorts. Earnings are a bit different in that there is premium on the board to absorb moves, thanks to the pre-earnings bid up. But that runs out at a price (see GOOG) and the squeeze is on. And the squeeze is likely more intense as more and more options become stock.
But would a plan that routinely shorts options pre-earnings do better if you avoided shorting names on Expiraiton Week? Sounds like yes, but it’s possible the market “knows” that outsize moves may feed on themselves on Expiration Week, and ergo bids higher. This I have observed anecdotally as well. Volatility tends to do poorly the week after expiration, even in names where news is expected. “Poorly” is relative. BIDU for example was bid up, but maybe the bid up would have been greater at a different time in the expiration cycle (all other factors being equal).
So yada yada yada, the moves may be greater on Expiration week, but I suspect the prices you get for selling gamma those weeks are greater as well. So net-net, I bet it’s a wash.
And with that it’s on to the NFL Draft. Let’s see, Giants are the DEFENDING SUPER BOWL CHAMPS and pick last, sweet last. Actually 31st selection , thanks to the Bill Belichek Art Film Festival. The show starts at 3PM. I’ll flip it on around midnight.
