SA contributor John Petersen castigates what he call's A123 Systems's (AONE -0.5%) "death spiral financing," which has caused a collapse in its share price. The financing "has created a toxic supply overhang that virtually guarantees significant future price erosion," writes Peterson. "Under the circumstances, I believe A123 is not a suitable investment for anybody but professionals."
