Matrixx Initiatives (NASDAQ: MTXX), maker of the allegedly scent-stealing Zicam nasal swabs, tumbled to a new annual low this morning on news that the Securities and Exchange Commission (SEC) is launching an informal inquiry. The SEC is requesting documents and other information regarding the warning letter issued to Matrixx by the U.S. Food and Drug Administration.

Last week, the FDA told consumers to stop using certain nasally administered Zicam products after the agency received more than 130 complaints from users who lost their sense of smell. Matrixx has defended its homeopathic, over-the-counter offerings, calling the safety concerns "erroneous," but the firm settled hundreds of lawsuits in 2006 with consumers making the same allegations.

The green shoots are getting harder to keep pumping up as it seems that Wall Street is starting to demand some visible improvements rather than the continued notion of just "less-bad" data. The weak manufacturing data today makes it look like the factories are taking a European summer vacation.

The good news is that producer inflation has not yet started working itself into the system, based on PPI data. The housing starts looked unbelievably better than estimates, but that was due to apartment projects rather than single-family activity.

Here were today's unofficial closing bell levels:
