Abio's Largest Shareholder Increases Their Position
According to the latest 13D Filing Atlas Venture Fund increased their position by approximately 300,000 shares. Normally, venture capital funds take advantage of increased liquidity-driven events to exit their position, but considering the fact that they're sitting on a huge loss, they have decided to average down. This is a positive sign leading to future events where they can book a profit on their most recent purchase.
Jean Francois Formela appears to have also increased his position in ABIO in 2012. However, I only have Form 4 information dating back to last October. It's possible that he also sold some shares recently that has yet to be reported.
Some of the institutions who bought into last year's private placements are blowing out their warrants. This may take a little time to digest before the next upward move. Stock is trading around 2 cents above the exercise price.
