Insider buying jumped to new 2010 highs in the week ending March 5th. Insider buying totaled $191.76MM while selling totaled $1.45B. Buying was substantially higher than last week’s reading of just $13.22MM. Selling was well off its high of $1.9B, but remains very high historically.
Of course, it's the buying that is most interesting because insiders sell for various reasons. They only buy, however, when they believe their stock price is going higher.
