Insider buying dropped again with insiders purchasing $14.89 million of their stock last week compared to $27.62 million in the week prior. Selling jumped sharply with insiders selling $3.46 billion of stock last week compared to $1.29 billion in the week prior. A large part of this increase was related to sales through secondary offerings by professional investors such as Bain Capital’s sale of sensors manufacturer Sensata Technologies (ST) and hospitals operator HCA Holdings (HCA) as well as CCMP Capital’s sale of generator company Generac Holdings (GNRC).
Sell/Buy Ratio: The insider Sell/Buy ratio is calculated by dividing the total insider sales in a given week by total insider purchases that week. The adjusted ratio for last week went up to 232.51. In other words, insiders sold almost 233 times as much stock as they purchased. After going up for 5 weeks in a row, this is the highest the ratio has ever been since we started computing it in June 2010. Excluding the aforementioned sales by professional investors would have brought the ratio down to 62.5.
