Another week and another (fourth-consecutive) set of positive insider-sentiment data from Vickers Stock Research. Let's jump right in, looking at exchange data. Vickers' NYSE One-Week Sell/Buy Ratio is currently 1.44 on a scale where any result below 2.00 is bullish. This ratio has been bullish for four weeks in a row. The ongoing strength in the one-week data has now also pushed Vickers' longer-term (eight-week) sentiment reading into bullish territory. Indeed, the NYSE Eight-Week Sell/Buy Ratio is now bullish at 1.83. Turning to the Nasdaq, the One-Week Sell/Buy Ratio is essentially flat with last week at 2.67, which is just into the neutral zone (which runs from 2.00 to 6.00). Still, the short-term Nasdaq reading has been generally improving for multiple weeks and has led the Nasdaq Eight-Week Sell/Buy Ratio (currently 2.98) on a trend of improvement that is now 10 weeks in duration. Putting this all together, Vickers Total (all exchanges) One-Week Sell/Buy Ratio is now 2.05 (oh-so-close to bullish) and the Total Eight-Week Sell/Buy Ratio is now 2.34 (neutral but having improved for 10 consecutive weeks). When this run of bullish data began back on April 7, the S&P 500 was at 5062. On Friday, it closed at 5686, almost 12% higher. On a sector basis, insider buying narrowly exceeded selling in Consumer Discretionary last week, with shares valued at $6.44 million bought versus $6.42 million sold. Buying also outpaced selling in Energy -- although volume was light, with less than $1 million shares bought during the period. Selling was the greatest in the Financial sector over the last week, with shares valued at $73 million sold versus less than $4 million bought. Selling was also notable in Healthcare, Industrials, Real Estate, and Information Technology. This week, analysts at Vickers highlighted insider transactions of interest at Molina Healthcare Inc. (NYSE: MOH) and BlackRock Inc. (NYSE: BLK).
