Well, in fairness, a lot of that stuff made a comeback in the last year just in time to blow up a bunch of funds during the corona crash.
Hedge funds and the like are not covered up the regulations governing retail clients and tradable products though.
There are dozens of types of options. There are unusual to very strange derivatives traded in the OTC market. Any quant in a bank can flex a bit his mental muscles and come up with a novel derivative.
that was bascially my job, I would produce a new idea every monday, every investment bank was the same back then. The more complex you make it the more potential payoff you could offer, e.g. 20% coupon (except the chances of getting it were slim and none). We would sit their scratching our heads thinking what new derivative we can come up with up that week based on some half assed economic report, which would have a counter view the following week Most of them made little sense. Quants produce general pricers using scripting language that can feed in any sort of fancy payoff, lots are like a sophiscated monte carlo simulation.
