Et tu, Eliot?H&R Block ( HRB) investors received a rude awakening on the Ides of March. On March 15, New York Attorney General Eliot Spitzer filed a $250 million civil lawsuit against the country's largest tax preparer, claiming the company was charging exorbitant fees for its "Express IRA" service. H&R Block, which prepares 20 million tax returns each year, sold this product to some 500,000 of its clients, allowing them to roll expected tax refunds into retirement accounts. The stock fell nearly 7% on March 15 and is off 14% for the year at Tuesday's closing price of $21.13. This slide comes after H&R Block generated a 13.9% compounded annual total return for investors over the past five years. The company's earnings trajectory has seen a similar descent. After growing per-share profit at a compounded annual growth rate of 29% from 1998 to 2004, H&R Block is on track to post its second straight annual earnings decline in 2006. So should readers buy H&R Block at Tuesday's closing price? In other words ( let's all say it together!), should I do it?
