What: Shares of the developmental stage DNA vaccine maker Inovio Pharmaceuticals plunged today by over 17% on exceptionally high volume. The apparent catalyst behind this drop was a large secondary offering of9,500,000 shares of common stock priced at $8.00 per share -- $0.54 below where the stock finished trading yesterday.
