Not sure anyone cares, but I closed some of the calls I'd written. (all of my Jan $370 contracts; I have two other strike/date combos left)

I appreciate you sharing. I have yet to close my Jan contracts I wrote back in August and early September. I know it makes sense to close them out here with so little return left in them, but I may just hold to expiration. I don't see much coming in the next 3mo that would seem to inspire higher prices for BRK, but the market always makes a fool of me.

You mentioned implied interest rates on Jan26 calls being about 100-150bps lower than Jan25 calls in post a month or two back. Boy have those spreads collapsed! I looked yesterday and implied was virtually equal across both at 7.7-8.0% on the lowest strikes. Mirrors what I see in my day job with longer duration rates moving higher even without additional central bank increases. Market guessers seem to believe higher rates are here to stay a bit longer than they thought, for now any way. I will to need to see some pretty low Brk valuations before I jump back in to any long dated calls at these rates.
