Quote from cdcaveman:
Good question.. I was asked many times the same thing about options from my friends when i start diving deep into options.. Curiosity i guess.. I know my curiosity teeters on beneficial and detrimental .. i'm interested in futures curves, interest rates, spreading, etc.. Interest Rates sort of seem to be a rather important thing that i know very little about..
What do you mean cash basis? what does Cash basis mean..
The basis trade drives most of the curve activity. The cash is the actual cash bonds and notes. They are bought at treasury auctions and in the open market. The futures markets are "implying an equivalent cash rate" but there are complexities with that which bring opportunities. Unlike most futures, interest rate futures don't really have an underlying product. They have an interest rate implied in the derivative. So futures trade on the principal of cheapest to deliver. This means if you are short the future, you get to make some decisions. As you know from futures 101, the short has to deliver to the long. In most markets, the long has the optionality. In interest rate market, it's the short who does. The short gets to go into the market place and "choose" which basket of cash rates to deliver to the long futures holder. The long does NOT get to choose. Think of it as an option where the short option holder gets stock "put" to him if he is short puts at exp that are ITM.
So the short futures trader goes into the market place and determines the most "optimal" and "beneficial" cash to deliver. The difference is known as the basis. It's the basis spread between the rate that the futures market is implying and where the cheapest to deliver is currently at. The basis spread is essentially a synthetic option on the difference. The goal is to sell futures at rate X implied and to deliver cash at rate X-Y with Y being the basis differential you are trying to capture. This can get very complicated but the value of the basis is constantly changing depending on the various duration and convexity of the cash product. In other words, the short future/long cash position is analogous to being long the corresponding option on cash.
Where the edge is, is being able to get the cash for a few basis pts in edge either through the auction or the open market. LTCM was notorious doing trades like these. They were better known as "on the run" and "off the run" markets. The off the run treasuries traded at a discount to CTD due to their lack of liquidity. So LTCM bought these at a discount, sold the futures and waited for convergence at expiration to get out. The
"on the run" tended to trade at a premium "because" of their extra liquidity and LTCM was generally net sellers of these.
There are millions of combinations you can trade here but the key idea is getting edge in the cash market. The futures market didn't have the edge. If anything they traded at negative edge as a by product of their added liquidity. So trading futures to futures was pointless. You are essentially giving up the edge on both sides AND you laid off your optionality on the long side which mean if you held to expiration, you were guaranteed to get the worst priced bond delivered to you (the most expensive).
Probably the easiest way to get involved in the game and I've talked about this on my thread is simply using the yield curve as proxy for risk i.e being long steepeners as a surrogate to being long stocks or long the flattener as a surrogate to being short stocks. And I mentioned there is an easy way to do this through the corresponding ETF's. But trying to trade the curve against the big boys with no edge is a recipe for disaster. There is NO retail money here for you to trade against. You are trading against the pros.
