Black Mesa Warns of "Massive" Liquidation by Another Hedge Fund

Could this create a chain reaction where lots of these Market Neutral Hedge Funds need to liquidate portfolios in order to meet margin calls? Maybe this is what is causing the insane whilesawing in the markets in at 3:00PM each day.

Black Mesa Capital, a hedge fund firm that uses computer models to
track down arbitrage opportunities, has told investors that at least one very
large hedge fund or investment bank is liquidating "massive" trading portfolios,
according to a letter the Santa Fe, NM-based firm sent to investors on
Wednesday. That's causing disruptions and triggering losses among other
so-called market-neutral hedge funds, Black Mesa said in its letter, a copy of
which was obtained by MarketWatch on Thursday. "Clearly, something is amiss in the markets that few in our strategy, if anyone, have experienced before," Black
Mesa wrote.
