With regard to my Twitter post.

After a tense week, it’s safe to say the market loaded up on hedges (bought puts).

When traders buy puts, market makers (MMs) take the other side of the trade, meaning they’re short those puts. To hedge, they sell futures contracts to offset the delta exposure. Since most of these puts are out of the money, their delta naturally declines as expiration nears. As a result, MMs adjust their hedges by buying back futures, adding upward pressure to the market.

So there are some supportive flows leading into OpEx (February 21st / 3rd Friday of every month for monthlies)
