Sure if you buy one stock and it goes up 1k percent it's possible. But that's unrealistic and being that concentrated is unacceptable for a fund.

Any sophisticated investor that read that a fund they were invested in a single name would be upset. Unless it's a special vehicle or they're activist and have a position for some strategic purpose. But just to let such a large percentage of your fund on a single name stock is insane.

I'll also add that options are essentially leverage. Leverage doesn't have to be borrowing it's just describing what $1 price change does to your position. You can buy at the money calls for 3-12% of the stock price. And they move up slightly less than $1 if stock goes up, so you're essentially getting 10-20x leverage. And if they're not above the strike price at expiration they're worthless

I don't have anything to say about their concentration beyond that if you read their early 13Fs (ex https://13f.info/13f/000204572425000006-situational-awarenes...) they were in fact "that concentrated" which is why it's plausible they got 100s of % returns without leverage. Re options being leverage - everything you said is true but unfortunately the public filings dont have strikes or durations so it's not possible to say whether they bought short dated otms with 0.05 delta or leaps with close to 1 delta or something in between.
