i don't think it's that simple. pretty much every asset class posting shitty returns this year, hell even bonds are in a bear market. so institutionals are gonna look at other managers and see a bunch of red and not necessarily stop alt allocations.
it's also relevant that you can't just ask for capital back as an LP. it's committed to a fund. you can not commit to another one but the price of much greater returns in alt assets is much lower liquidity.
