Early assignment worked in my favour today

I was short a few QQQ puts that expired today with a strike price of 458. I woke up this morning and saw that I was already assigned. I was ultimately planning to roll the position, but I was going to do that a few hours after market open. Since I was assigned and I did not want to hold the shares, I sold the shares shortly after open. QQQ proceeded to drop several more dollars. When I opened a new position several hours later to effectively roll the prior position, I was able to get a much more favourable strike than I would have had I not been assigned.

TLDR: assigned QQQ puts early, but came out ahead due to early assignment.
