If you've got a basket of bank stocks, which are notoriously underweighted in the S&P500, for example, you're not going to get the same kind of moves. Not even close - that's obvious. And that is also the reason for which firms and funds trade baskets of stock. If my performance is indexed against the S&P500, I can buy the futures or the DRs (SPY). Same thing with the Nasdaq100 and the Q's. That's a passive portfolio strategy, which few investors and even fewer plan sponsors will pay for; they could do that themselves, in house. But if I seek to actively manage a portfolio in such a way that my exposure is largely the same, with proprietary models over- and underweighting certain issues as per performance expectations, well, I have to build that take on the S&P500 (or whatever index) from scratch. Also, quant shops will build lists of stock that are highly correlated over a limited time period and have absolutely nothing to do with one another in sector. They could appear a disparate mix of listed and OTC stocks that in reality share certain risk characteristics that make them similar, albeit fleetingly. For this reason, these lists of stock have to be generated, the trades executed and at the appropriate time liquidated - and may never in that exact form be utilized again, as the underlying fundamentals shift. Futures products and DRs don't, and will never, have a broad enough audience to make the packaging of this kind of product worthwhile, and the very nature of the composition of such lists is proprietary and unique from firm to firm.
