If, by later this evening, no SEC Form 4 has been filed to disclose trading by a 10 percent holder of Mattersight, as of last Friday, it would be a fair guess to assume that many differing index funds were the contract-buyers (or call purchasers), at last Friday's close -- in anticipation of being told that Mattersight would be added to the Russell 3000 Index.Many exchange-traded mutual funds mimic the results of the Russell 3000 by buying a value-weighted portion of each of the 3,000 components. We shall see. But it is a plausible alternate explanation, geven that we learned this morning that the Russell 3000 has added MATR. It would ALSO certainly be permissable for underwriters or broker-dealers acting on behalf of IGC Fund IV, LLC -- under the 424(b)(3) resale prospectus -- to arrange off-exchange purchases of chunks of MATR, for each of the mutual funds that mimic the Russell 3000 holdings. We may see much more, this evening.
