TPM bats down the allegations:

The Romney campaign said Ryan had nothing to do with the trades in the first place. They were part of a Russell 1000 index fund that automatically traded stocks as part of a pre-set formula. Ryan’s disclosure forms include several similar trade patterns at various points throughout the year. In a statement provided to TPM through the Romney campaign, Larry Gaffney, the independent accountant for the partnership who handled the trades in question, said the stocks were out of Ryan’s control.
