Signs look favorable for a thrust that could eventually push Silver Wheaton above its all-time high at 47.60. There are two bullish things to note in the accompanying chart. For one, last week’s chop looks like a consolidation above the big pattern’s 39.17 midpoint. And for two, before the consolidation began, the stock poked above the look-to-the-left peak at 39.95, refreshing the bullishness of the intraday charts. With a rally target as high as 48.54 in prospect over the next couple of months, a very low-risk way to leverage the move would entail legging into a butterfly spread targeted on the 48 strike. I will provide further details during market hours as a specific plan comes into focus.
