Why would anybody exercise early a DITM ES option?

I'm a bit puzzled. Your hedge and your option premium should move in opposite directions, right? Also, why wouldn't you simply adjust the hedge by buying or selling more of the underlying as the price moves? Given the changes in gamma, seems like you'd be making money in either direction.

(I'm brand new to figuring this stuff out, so I'm not making any assertions - simply wondering what I've missed.)

Can't help you, I've been up since 3am.

Given the associated changes in gamma, seems like you'd be making money in either direction. By exercising early, it seems like you'd be throwing away all the extrinsic you've paid for.

I won't pretend to know exactly what nooby_mcnoob meant before lack of sleep (or excess of alcohol, it's saturday night) catches him.

The underlying of ES options are ES futures. The nominal value of 1 ES future is more than 150k$. So in practice, it might be difficult to adjust by buying or selling more of the underlying as you mentioned.
Any new ES contract that you might buy or sell will have more impact than each slight change in your options delta unless you have hundreds if not thousands of DITM options. Possible but needs quite a big account.
Plus you might not want to change your futures exposure for plenty of reasons.
Saturday night for me as well so I hope beers didn't talk on my behalf.
 
Also, let's say you have a DITM call option with strike at K and currently, the price is of the underlying is S with S > K. The intrinsic value of your option then is:

I = S - K

If P is the premium paid, then the price of your call option is:

C = P + I

Let's say you bought the option for a hedge and you are now expecting the price of the underlying to decline by $s where s > S-K (so still DITM). So the new value would be:

I = (S - s) - K
C = P + (S - s) - K

But P has also declined:

C = (P-p) + (S-s) - K

In order for you to maintain the right hedge, you might decide exercise so you don't lose p+s in exposure.

I retain the right to say I have been up since 3am.

Ya lost me at little s. It's greater than the old intrinsic but somehow still DITM? This is why I always say, stop with the formulas, these are real products, put numbers to it

You have heard of MES, right? That's one of the benefits.

But in any case, you're going to take a loss by exercising before expiration. A loss you would not have to take by simply selling back the hedge. So the question here is, what would be the benefit of exercising vs. selling? Does one even exist?

[laugh] We're all walking wounded here for one reason or another today, it seems. Me, I'm just learning how to hedge effectively, so I've got that newbie zeal (and curiosity, too) going...

I get the sense that you have found trading crack, with the granularity of the MES/other micros.

Like, bug-eyed giddy and shit. It is so refreshing to see.

Gotta remember: hedging is just a tiny part of the picture. I'm gonna be slaving away in these salt mines for a LONG time yet. Good thing I like salt.

But yeah, I always get pretty happy whenever I get one of these concepts down. I work damn hard for it, and when it finally breaks through... aaah, the joy of comprehension. That is my drug of choice.

Then I hope you remember the idea of comprehending a VACATION! Remember? No work for j00, one week!

Now, now. This "vacation" is going to be a week of playing with options and futures in sim. "No work"... shyeah, good luck with that one. Pulling me away from this stuff is going to require a locomotive, and I'd leave nailtracks in the asphalt.

I'll take a real vacation - like a month of sailing the Med, or maybe my old stomping grounds in the Caribbean - once I'm averaging at least half of what I make working. Until then, it's nose to the grindstone.

Yes correct. MES would be helpful.
But last time I checked MES has a wide bid-ask spread and commission per dollar of nominal value was much higher

I guess it's a cost balance between the 2. In one case you would have to buy and sell options and may be futures, in the other case you exercise at a small loss (the time value) that can be close to 0 if option is very DITM.
Back to the original topic, if you were selling that specific DITM call in a combo like a box, the small profit you get from the early assignment will probably not compensate the troubles caused by that missing option in your combo. It's no more a box but a bet on ES going down.

Hahahaha indeed
Curiosity is a great learning power.
