http://www.mercurynews.com/mld/mercurynews/news/local/12456297.htmInvestors retreated Tuesday, sending stocks moderately lower as existing-home sales slid and volatile oil prices intensified Wall Street's summer malaise. The tech-heavy Nasdaq composite index fell 4.16, or 0.2 percent, to 2,137.25. Silicon Valley's largest tech stocks by market value were mixed. Cisco Systems, Google, Hewlett-Packard and Oracle gained. Intel, eBay, Yahoo, Apple Computer, Applied Materials and Symantec declined. The Dow Jones industrial average fell 50.31, or 0.5 percent, to 10,519.58. The Standard & Poor's 500 index fell 4.14, or 0.3 percent, to 1,217.59.
Investors sold off stocks after the National Association of Realtors said sales of previously owned homes dropped 2.6 percent in July as mortgage rates crept up. Even with the decline, sales were the third-highest level on record.

Still, in late August trading, it doesn't take much to bring stocks down. No major economic reports are due this week, most companies' second-quarter earnings are out and many investors are on vacation, said Michael Sheldon, chief market strategist at Spencer Clarke. ``We're not seeing a lot of conviction, either by buyers or sellers, so far this week,'' Sheldon said.
