Although we usually come to our trading desks Friday morning intent on fading the opening bar with the purchase of put or call options, there was little to inspire this as the dust settled on Thursday. Was the weakness signaling a reversal of a rally that has been relentless since Christmas Eve? If so, we’re not likely to see put options on sale at the bell. It also means that the Dow’s 220-point plunge could provide a running start for even more serious damage as the week ends. Brace for an interesting day in any event.
