IB requires increased initial and maintenance margins for some high volatility stocks, i.e. 100% initial and maintenance margins are required in lieu of the usual 50% and 25%, as per Reg T. In fact, I have seen a 500% short maintenance margin requirement for one particular stock.
I think I understand why IB does it. My issue is that even though I mainly trade these risky stocks, I construct my portfolio in a way that keeps its overall volatility very low, a daily VaR of less than 1%.
Given that the downside risk of my strategy is low, I really would like to lever it up. But I can't because of the special margin requirements for these stocks. I tried clicking "Try Portfolio Margin" in TWS but it doesn't seem to change things a whole lot (my excess liquidity increases by a few %, that's it). Anything else I can do? I really do not want to leave IB because their short inventory is so extensive. Any ideas? Thanks!
