RE:I've lightened my position in WELL again...If you're talking about the SEDI June 21 insider report, it was an exercise of rights and subsequent sale of a portion (20%-50%) of the shares purchased usually done to cover or partially cover cost.
After the exercise of rights to purchase shares and the partial sale all participants ended up with larger holdings than they held before. In fact, Fong acquired 24,282 shares and did not sell any.
Since the directors and some executives all did it at the same time this is almost certainly raising cash for a specific end. Possibly an upcoming purchase.
In the July 5th report Liston sold 9,100 of over 614,000 shares, or 1.5% of his holdings, a net change over the two transactions of ~5000, less than 1% of his holdings.
