Silver Wheaton topped a list of precious-metal buy recommendations sent out a few days ago by George Carson, a New Zealand forecaster using a technical system that he says has produced no bad signals going back two years. The “buy” was generated on April 17, but so far SLW seems reluctant to oblige. Indeed, by my runes, the stock looks vulnerable over the near-term to a fall to 6.63, a Hidden Pivot that lies about nine percent below these levels.  If this occurs, I’ll recommend buying 200 shares, no stop.
