R.H. Donnelley

R.H. Donnelley (RHD) publishes Yellow Pages phone directories and has the distinction of being the worst-performing stock in the small-cap Russell 2000 index so far in 2008. Shares now trade at below 1 after losing 99% of their value since the end of 2007. Advertising sales fell 8% last quarter, but investors' major concern may be the company's debt load, which executives hope to reduce to below $9.5 billion by the end of the year.
