The week's question
In March 2025, in the thread "Re: OT, out", Umm asked the members: "Do you think it is because America is made up of magical soil that makes businesses based in America magically profitable?" This week it is put to everyone again. The button below opens the small thread re-asking it - read what others have said so far, then give your own answer as an ordinary reply.

Jim repeatedly said options move strongly when their strike price is reached. Really? I am a bit sceptical because of my current experience: In March I bought lots of BRK out of the money puts (Sep+Jan ones, strike 395/400/405/410). Last week with BRK around $405-410 I sold the $400's for $13.50. With BRK/B now at exactly their strike of $400 I expected the price of those puts to be a lot higher. But no. While Bid/Ask is $13.5/15.5 the last actual transaction was done for a mere $12.15 = instead of higher a lot lower.

???
