The average salary of a hedge fund PM: “We gave a range of $500K to $3 million USD in the hedge fund career path article for the “average” PM, with median pay in the high-six-figure-to-low-seven-figure range.”

that salary comes from a % of returns. let’s say the fund makes a 20% return in cards per year, and the hedge fund manager gets paid 5% and the investor takes 15%. let’s also assume the lowest paid hedge fund PM at 500k - i.e. you need to invest in US$10mm worth of cards to pay him his salary - can you find US$10mm worth of cards to buy at fair market value? and even if you could, can you outperform the market given you’re likely buying everything on sight?
include the infrastructure, legal team etc. which costs millions per year to maintain, and it becomes quickly apparent why you don’t really see hedge funds investing in collectibles. the market is just too small. even if pokemon card values were 10x-50x higher the market would still be too small
tldr - never happening
