May Silver hit an air pocket Thursday morning, dropping 70 cents, or nearly four percent, in the space of an hour. From a technical standpoint the kamikaze dive tripped a short-sale signal at 17.755 that is tied to a 15.355 target. I expect the nastiness to come down to at least 16.948, the midpoint pivot indicated by the red line. If bulls are going to turn things around, that’s where they’ll have the best chance of succeeding. If the futures instead crush the pivot, especially the first time they encounter it, that would shorten the odds of a completion of the move down to 15.400.
