A123 Systems (AONE -7.3%) has plunged to new lows in the absence of major news. Shares have triggered short-sale curbs, but given they now trade at a paltry $0.224, brokers are probably reluctant to lend shares regardless. 19.6% of A123's float was shorted as of Aug. 15. A123 was hurt last week by news GM is temporarily halting production of the Chevy Volt.
