That means, roughly, that if you give chanos $1M, he will short $900K worth of stuff, and go long $1.9M worth of stuff. This product is actually 100% net long, like a typical mutual fund might be - but it has 280% gross leverage. The $1.9M worth of long stuff is usually just the US market; something like just buying $1.9M worth of SPY.
Can someone help me with this math? If you short $900k of something, you have to give $900k in cash (or other) collateral. That leaves you $100k left to go long.
You don’t get cash for shorting. What am I missing?
