I hace access to some prop. content,which I cannot link to or publish completely on this board.

Its about some shark-like attacks on quant funds by other funds. Here is an excerpt :


Among other major New York-based managers, the $29 billion multi-strategy shop D.E. Shaw & Co. is down as much as 20% in certain portfolios while Tykhe Capital LLC, founded by former D.E. Shaw employees, may have lost 27% year-to-date.

The losses have been exacerbated by investor redemptions that forced fire sales of fund holdings in panic-stricken, frozen markets. According to Merrill Lynch economist Richard Bernstein, "Some equity hedge funds and quantitative long/short equity funds are now liquidating positions at decidedly unfavorable terms."

In a research note explaining the losses, Mr. Bernstein suggested that this year was the most difficult period in the past 18 years for long/short equity managers to out-perform the market and that therefore they were tracking the market and levering to enhance returns. Others have also pointed out that there was a high and rising correlation between hedge funds gains and the equity market. Many hedge funds followed stock prices up and, more recently, down Previous HedgeWorld Story.

One manager who might profit from the situation is Steve Cohen of SAC Capital. His team is said to have taken the unusual step of running algorithms in reverse in order to profit from the confusion. Mr. Cohen and other SAC executives own a large chunk of the capital they trade, while their outside investors have agreed to long lock-ups. Hence SAC is less threatened by redemption demands and forced sales than many funds.

Couple of things: Shaw is quant firm that discourages the use of technical analysis. It's all about the statistical arbitrage, as developed by a hundred mathematicians with PhD's from MIT, Stanford and the Wharton School. Cohen, on the other hand, looks at charts. He has his quant guys and he looks at that stuff, but he's a pattern analysis trader...looking for resistance/support, breakouts and the rest of it.

Yes, thats the impression I got from reading about both of them in Market Wizards.

But it is fascinating to me that SAC could/would be running the algorithms in reverse to make the markets go out of sync and cause enormous pain for the quants. Now, that would explain how the Alpha fund lost 15% in a week.

Another question would be : how much volatility was due to quants unwinding leveraged bets on small statistical discrepancies and is that forced selling over ? If quants sit out the market for the next several days/weeks, what impact does it have on trading and prices going forward ?

Can we have days where ES decreases far more than ER2 ? Big down days where implied volatility barely budges ? (example today). Will there be large swings in $PREM ?

I'm not sure I believe this about "running algorithms in reverse."
It's such a bizarre concept that I'm not sure someone somewhere is being kidded.

sounds to me like the reporter is trying to explain in laymans terms the gist of what they are doing - I am sure they will not be just "inverting" entire algos.

From what I hear, SAC has very good quants, but the empasis with them is these guys need to be creative too - creating something different - from what Ive seen elsewhere, this is rare.
