Jeff Immelt, former CEO of GE, was the person who acquired 70,000 shares of stock at an average price of $14.86 per share for more than $1 million in purchases.
The reason Immelt's purchase is so notable is because he is on the Board of Directors at Bloom Energy. As a board member, Immelt invariably gets inside information about the company's direction; the fact that he was bullish enough to put $1 million of his own money behind the company is seen as a good sign.
