    Being assigned early is a good thing...

    There are only a few true reasons for exercising early:

    - exercise of ITM calls due to upcoming dividend
    - exercise of ITM puts due to high interest rate cost of holding stock in combo with ITM puts
    - exercise of ITM calls due to extremes in short stock lending...

    Any other situation, if you're assigned early you will gain due to early capture of the interest component or better yet the premium above intrisic value.

    In the 3 mentioned situations, the call or put will have a delta of 1, so swap for the stock shouldn't make a big difference... unless you can't make the payment or deliver.

    I personally would love to be called early... money in the bag

    Good post, but disagree on a few points.

    Yeah, generally, early assignment is great, assuming that the assignee has the capital to cover the UL. I almost always trade this way, although early assignments have been rare.

    Generally, if the option has a delta of 1, early assignment becomes very possible, regardless of the reason for delta = 1. Sometimes, it is not easy to determine the exact true value of delta.

    In the case of American style ITM calls and upcoming div. it is possible to lose on assignment because the Euro value of the call is below parity. That's why these options are exercised, because pre div. parity is a greater value than post-div. value.

  9. How about:

    1. Early assignment Only for American options!?

    2. Any short options could be early assigned, regardless of delta value!?

    True, the terms of the contract are the key. It's all about the probability of early assignment.

    If the option can be sold for more than parity, then the market value is greater than the exercise value, so, generally, those options will not be exercised early.

    Some years ago I experienced a strange case of assignment where the options had considerable time value left, but I think that that is rare and happened more often in the early days of option trading.

    Unshortable or HTB stocks are another case where early call assignment is undesirable. If you are bought in by your broker, then the position becomes out of balance. One assumes that one can hold the stock, but that is not always the case.
