If you think they are going belly up this year it is far cheaper and safer to buy a put. You risk losing the money you spend for it up front but your losses are capped. Right now the 25 strike for a DB Jan 15 2027 put is 2.50/2.85 bid/ask. DB is sitting at $29.44 as of yesterday's close. That's $285 bucks up front that gets into the money if DB falls beneath 22.15 by Jan 15th 2027. But if it moves down sharply in the near future you could just turn around and sell that put for a profit long before expiration.

This is not financial advice, it is gambling advice.
