Insider selling eased to $5.09 billion in the week of August 17 and reported buying fell 39% to $309.6 million, but the composition is what stands out. Officers and directors accounted for just $79.2 million of the buying, 26% of the total and the lowest share in the twenty-six weeks we have measured. A single 10% holder, Bill Gates’s Cascade Investment, put up $216.0 million of it, adding Republic Services for the second straight week.
