This I posted a while ago to answer a question by saying that my BRB puts are a very significant part of my portfolio and not just "nipping around":

My BRK puts currently represent 6-7% of net assets.

The other serious part are my Berkshire shares themselves which (I sold a lot lately) still represent over 50% of net assets.

An update: Today those BRK puts did gain a full 10% of net assets and I sold all June ones as they gained on average 170% and are the ones closest to expiration. Nevertheless thanks to today´s extreme gains the remaining Sep+Dec+Jan ones probably still represent at least those 6-7% of net assets, so still a significant part.

One more comment: I would NEVER do such extreme investing, no, clearly SPECULATING(!), with anything apart from Berkshire, as past experience with Tesla and Saas are proof that I am completely unable to even halfway correct predict what any other stock will do --- and whether that with BRK puts was/is just luck ... very very possible/likely.
