Dow continues to trail its counterparts as it slogs along with a modest loss. 3M (MMM 84.00, -0.68) continues to weigh on the index of blue chips, but IBM (IBM 143.89, -1.09) has actually become the heaviest drag of all. In contrast, Dow component Cisco (CSCO 19.77, +0.42) has attracted strong support. That has also made it a leader on the Nasdaq, which has managed to sport a modest gain for most of the session.
