This rule must be rejected. As if the game wasn't rigged enough against household and small investors, passage of this would only enhance large firms grip on the market. Decreasing margin requirements further incentives risky bets within a system that is already highly leveraged. I believe this rule change would increase systemic risks. I am also gravely concerned that selectively decreases margin requirements to bail out bad bets could have the potential to influence equity price action in a manner that is antithetical to a free and fair market.
