Quote from cstu:
I would love to increase my stakes at the blackjack table but at what cost? We keep talking "risk" based borrowing with no talk of the risk.
I will make this easy What is my per annum charge if I put up $100,000 and buy and hold one position of SPY $1.5 million worth?
What is my per annum haircut if I put up $100,000 and have two positions short $1.5 million QQQQ and long $1.5 milllion SPY.
I am not looking to hold anyone to this but want to better understand how someone is coming up with a "risk-based" calculation in markets that don't set "haircuts"?
Do some checking into pairs trading, for example (
www.pairtrader.com) and into the opening only strategies used on the NYSE (see "Don's openings and more" thread, check out "Lescor" s recap for 2005 as an example of someone "using" capital, not "risking" capital.
Another easy example: (Opening Only orders on NYSE, to trade "with" vs. "against" the Specialist). If you send in 2,000 shares to buy, 2,000 shares to sell short on 40 stocks each day prior to the opening (assume average price of $40.00)...that equals $6,400,000.00 worth of "Opening Only" orders. You cannot be filled on both buys and sells, so the "use" is cut in half immediately. ($3,200,000.00 now) You look for a 10-20% "fill ratio" so you are actually involved in between $320,000 and $640,000 worth of stocks at any given time. Your goal is $5,000 per week doing this (or more). If all 8 stocks move 10 cents against you at one time (very unlikely) then you "risk" $1600 for this.
This use of capital relationship is how traders on the exchanges work with their Clearing Firms. Firms like ours do the same thing, except you don't have to be a seat on the Exchange or be responsible for "making markets."
Just trying to help explain the concept, hope this helps.
