encore, im no expert but if lets call them "evil trader 1" borrows stock from "evil placement recipient 1" and subsequently sells it on market for X dollars and in doing so spooks the market into a downtrend THEN buys the same qty of stock back at X * say 0.8 (80% of original selling price) and hands the stock back, then they have MADE 20% in profit, in their account. withou the need for a SP appreciation at all.

thats how i would do it anyway.
