Black Mesa Capital, a hedge-fund firm that uses computer models to track down investment ideas, said that at least one large hedge fund or investment bank is liquidating "massive" trading portfolios, according to a letter the
The warning is causing disruptions and triggering big losses among other so- called market-neutral hedge funds, Black Mesa said in its letter, a copy of which was obtained Thursday by MarketWatch.
"Clearly, something is amiss in the markets that few in our strategy, if anyone, have experienced before," Black Mesa's managers,

Such "quant" funds are popular among hedge-fund investors. Many use a market- neutral strategy, which aims to balance long positions with short trades, or bets against securities. Others are so-called statistical arbitrage funds, which analyze the historical relationships between related securities and trade when those relationships get out of whack.
Many players in this part of the hedge-fund business have similar positions and use lots of leverage, or borrowed money, to increase their bets. However, that magnifies even small losses. Some of these hedge funds also have relatively permissive redemption periods, allowing investors to take their money out every month, with 30 days' notice or less.
So if losses trigger investor redemptions, these funds may have to sell lots of their positions. That, in turn, puts more pressure on the historical relationship between related securities, handing more losses to other hedge funds in the space.
If such positions are sold by lots of managers at the same time, the most leveraged funds get hit the hardest, possibly forcing big liquidations of portfolios, which triggers a chain reaction.
Two hedge-fund investors who didn't want to be identified said the current turmoil is reminiscent of the 1998 collapse of Long-Term Capital Management.
That giant hedge fund had some arbitrage positions based on the historical relationship between related securities. It made bets on the relationship between the prices of government securities from around the world. When

AQR Capital, Algert Coldiron Investors and Tykhe Capital were among other hedge fund firms mentioned by investors. Representatives at those firms didn't return calls seeking comment on Thursday.
The Wall Street Journal reported that Tykhe, run by former D.E. Shaw managers, has suffered losses of about 20% in August, and is moving quickly to trim its investment positions.

Black Mesa then began to wonder whether others in the market-neutral space, having learned of these liquidations and having lost money themselves, could start cutting leverage in their own portfolios too.
"There was (and is) the possibility that, as great as liquidations had been so far, that it was just the beginning of a spiral of me-too liquidations," DeMers and Spring wrote.
The two managers said they didn't know now long such dislocations could last, noting that it could be two days, two weeks, two months or even two quarters.
Black Mesa said there are now "enormous profit opportunities" but the firm said it remains on the sidelines until signs of liquidations in the market dissipate.
