Ice, Here are some definitions that should answer your questions. Spread: The spread is the difference between the S&P 500 futures (F) and the S&P 500 cash index (C). The formula for calculating the spread is F-C. For example, if the S&P 500 futures last traded at 976.30 and the S&P 500 cash index last traded at 973.09, the spread is 3.21. Fair value: The S&P 500 futures settle on the third Friday of March, June, September, and December. As time marches forward, the futures converge toward the value of the cash index because the futures settle at the cash index upon expiration. A curve can be plotted that shows the fair value of the spread for each day in the cycle. I think the curve is logarithmic (maybe Nemer can verify). CNBC reports the fair value each day and Nemer reports it every now and then gg. Discount: A negative spread. This indicates bearishness in the S&P 500 futures pit. When the spread becomes sufficiently below the fair value, sell programs will be initiated. Premium: A positive spread. This can indicate bullishness in the S&P 500 futures pit. Normally, the spread is positive, but it's not until the premium becomes sufficiently above the fair value that buy programs will be initiated. Buy program: When the spread becomes sufficiently above fair value, arbitragers initiate buy programs by selling the futures and buying the stocks in the S&P 500 index. They reverse their trades when the spread returns back to fair value and the difference is their profit. Sell program: When the spread becomes sufficiently below fair value, arbitragers initiate sell programs by buying the futures and selling the stocks in the S&P 500 index. They reverse their trades when the spread returns back to fair value and the difference is their profit. At about 2:15 p.m. today, the spread between the S&P 500 futures and the cash index got to about -3.50. This is a very big discount and prompted arbitragers to initiate sell programs. Even worse, the futures traded at a discount to cash for at least 30 minutes prompting more selling. Since LSI is in the S&P 500 index, one might have expected it to get hit given the magnitude and duration of the sell program. The DJIA fell over 100 points in a short period of time but LSI held at 11 1/2. The bid even increased from 11 1/2 to 11 9/16 during this time. I think this bodes very well for the stock next week because it may give investors confidence that the stock has bottomed at 11 1/2, prompting more to hold and more to buy. Dan PS to Nemer: My connection went down just after I sent this the first time and I had to retype it. I see that you already answered Ice, but I spent too much time typing it and I'll be damned if I'm not going to send it ggg. Thanks for your input.
