Small % of my portfolio making sure there is ample excess liquidity. I tend to buy calls on stocks I already like and own that have multiple down days in a row for no good reason (recently CPNG and BRK). The idea being that the stock is already undervalued but also it may be due for a short term bounce regardless. The key is to also be aggressive in selling when it pops but also if it doesn't jump am willing to take a 50-90% loss and roll forward. Definitely don't want to play the buy and hold game. I've had multiple situations where I lose like 50%+ on multiple rolls, but then eventually one hits and am up 100's% and it makes up for all the losses and then some.
United health this year and last was a good one. Loss, loss, loss, and then huge gain and overall positive return. You have to be willing to take big realized losses and have the guts to keep reinvesting. Sprinkle in some put selling when the IV is high which it usually is if the stock drops a bunch. Put selling I keep at like 6 months expiry max.
Berkshire is a special case because the IV is super low as it generally doesn't move much, but then you have days with big jumps where you can sell. Also, it's the one exception where I don't mind selling LEAP puts. I've shorted a bunch of Dec 2028 puts (the furthest out at this point). It's a big hit to my excess liquidity, but am willing to take that chance because it's Berkshire and there is a countercyclical component to the stock, and it hasn't done anything in 2 years, big cash position, buybacks, etc.
