Sure, opinions are easy. I covered mine back in May. I had Jan23s and once I was able to capture about 60% of the premium I covered.
I preferred to have the freedom to do what I wish with the underlying brk pledged against.
I too closed mine on the last dip. The majority of the maximum possible profit in a minority of the elapsed time.
But I thought about it afterwards…perhaps the question is not the remaining rate of return, but on what you think/now you would do in future.
Berkshire’s intrinsic value is going to rise only so much by year end, so that can be estimated.
If the price went back up to a high multiple of that sometime before expiry, would you still be a willing seller?
If so, why not get paid now, even if only a small amount, for committing to do what you were going to do anyway?
So letting them run off, collecting a modest rate of return on no additional capital committed, would make some sense.
A key observation is that a short option written against an existing stock position does not tie up any margin cash, nor increase your capital at risk.
The main argument for closing them for a tidy profit when given the early opportunity is only that prices go up and down. And up again.
If the price goes up again, you and I can sell fresh calls at a high price again, again “covering” the same block of underlying shares.
If someone doesn’t see themselves doing that round trim again, and still thinks they’d sell some
stock if we saw those high prices again, there is a case for letting the calls run to expiry.
After all, a little cash is better than no cash…if there is no downside.
The strange thing is that this line of reasoning leads to an odd proposition:
For someone who does tend to lighten up at high valuations (whether temporarily or permanently), it would be logical to write high strike calls at all times.
Even at quite low rates of return.
I am definitely a person who lightens up, and I don’t immediately see a hole in the reasoning, but I can’t bring myself to do that. Yet.
Imagine you buy a Christmas tree every year. You definitely plan to do so this year, and there is no financial or practical hurdle preventing it.
Now, somebody walks up to you in June offering to pay you to commit to buying a Christmas tree this year.
(not from him, not at any particular price, just in general a commitment to buy a tree).
It’s not a lot of money, so you’re tempted to say no. But why not?
In a way, it’s just one more demonstration of how the person who knows what something is actually
worth has a huge advantage, whether it’s a single stock, the broad US market, or coastal land in Florida.
There are lots and lots of ways to do well if you’re informed about the likely value of something.
The discussion on writing calls is just one among many.
