Its a somewhat rhetorical question, with the assumption that there will be a 'reloading' in a massive way.
Once funds stabilize by meeting proper margin requirements on their subprime debt holdings, isn't it a -very- likely possibility that the very same funds selling stock (and covering shorts) to raise funds to meet margin calls will reload positions ???
I know when I've been on a tight margin what I've done upon getting my account straight -- I quickly reload after shuffling things around.
Fundamentally the quants don't disappear, and their valuation models, derived from painstaking research, will drive their buying and selling decisions.
I see two large primary barriers to a quick 'releveraging of their positions': 1) obvious continued instability of credit markets and its cascading effect on other asset prices (noteably subprime mortgagebacks), 2) impatient hedge fund investors pulling money out of these funds at the most inopportune times, pushing cash out of the funds.
Reading this article I can't help but think that this event of equity selling is as much if not moreso a -technical- event than solely a fundamental event.
The bears are always arguing for imminent recession, and even I will agree financials' depressed valuations may be appropriate in a response to fundamental change in the credit markets -- they will do less business likely.
A broader step of what makes price: In these markets the participants generally agree on terms of valuation (ie P/E, growth estimate, risk premium, etc), but at the same time the -actions- of buyers and sellers are the final say.
ie if you have a market of 10 participants, and 5 of them experience unforeseen adverse medical events, even a stock that makes more $$ when people get sick may go down, since half of the participants may be liquidating positions to cover their mess in personal finance.
So here and in what we see, its clear valuation models are trumped by investor disposable cash reserves when deciding what stock or commodities are worth.
A lesson to those who view valuation and price in more static terms.

Dear Renaissance Investor,
As promised in my July letter, posted today on the RIEF website, I want to share some thoughts on August-to-date performance in order to provide perspective on a most unusual period.
RIEF results through July 31 were below expectations, but not extraordinarily so. I've previously stated that the low volatility Basic System, to which our predictions are added, was not in sync with the market during much of this period. Nonetheless, we remain confident that over time the Basic System will match the return of the S&P and, enhanced by our predictive signals, should exceed it. Since we do not attempt to track this or any other index there will be periods of positive and negative relative returns.
August (down 8.7% through today) is a different story. The culprit is not the Basic System but our predictive overlay. While we believe we have an excellent set of predictive signals, some of these are undoubtedly shared by a number of long/short hedge funds. For one reason or another many of these funds have not been doing well, and certain factors have caused them to liquidate positions. In addition to poor performance these factors may include losses in credit securities, excessive risk, margin calls and others. All of this may not influence the direction of the overall market, but it may certainly alter the relationships of stocks to each other in a dramatic way. Given the undoubted partial overlap of our portfolios, these liquidations have had a negative impact on RIEF.
Other examples of such liquidations are the meltdown of risk arbitrage positions in the October 1987 crash, the forced liquidation of junk bonds around 1990 and the collapse of European bonds in 1994. Some of these were in the midst of a bear market, some not.
Such events tend to occur extremely infrequently. We cannot predict the duration of the current environment, but usually such behavior causes first pain and then opportunity. While we may hedge out some market risk, our basic plan is to stay the course and, as conditions revert to the norm, we anticipate the possibility of an attractive opportunity for RIEF. Our firm remains strong, and although Medallion has experienced some losses in August, it is solidly profitable year-to-date.
We are confident in our approach, and we urge you to contact our staff should you have any questions.
Sincerely,
Jim Simons

The BOYZ had to learn their lesson the hard way, i.e. recalibrating and "RISK"-adjusting their L/S, RV and whatsoever "models"...but more importantly : they will think twice about the meaning of LEVERAGE and HERD LIKE MENTALITY
