CAR seems to be riding the HTZ pump, but its options are much pricier since the shares are 10x more a piece. The CAR pump wasn't nearly as big as the HTZ pump either which makes it less attractive for a trade.
HTZ use a low interval like 15 minutes or even 5 minutes to trade on and keep an eye on momentum. Hertz is a highly liquid stock and it's low price per share makes the options affordable and easy to average into. There's likely to be a chance to make money shorting next week.
HTZ will give up the gains. Tariffs will help used car sales, but will cost more for HTZ to update their fleet. It is time to short before the next earnings.
