Thanks for "risk free" return. Operation Twist as defined by the Federal Reserve (FED) is planning to sell Short-term bonds (up to 2-year bond prices down, yields up) and using the proceeds to buy Long-term bonds (bond prices up, yields down). Aim is to reduce long-term interest rates to encourage long-term borrowing to fund investments.
Because of this Operation, it has been an animal instinct to take advantage of situation. If you know that someone is going to buy something (@ prevailing market price), you would like to engage the activity of "Buy High, Sell Higher"...
