COSTELLO: Have you checked your 401(k) around this time? You better change your plans. On Wall Street, we're just about an hour into the trading day and already we're seeing a sell-off. The question is why. The woman who knows is Alison Kosik -- good morning.</s>ALISON KOSIK, CNN BUSINESS CORRESPONDENT: Good morning. So this is a bird's eye view into how these earnings reports from some big companies of names that you may recognize -- Wal-Mart and Cisco. How these earnings reports really reflect how the economy is affecting them. So what I'm talking about first of all is Cisco systems, its CEO John Chambers coming out today in an earnings report saying that the economy is in tough shape and you're seeing investors take notice. As we see Cisco shares sell off 7 percent lower; the broader market -- the Dow down 216 points. Investors notice this Carol, because how Cisco does usually mirrors how these global economic trends. The company also announced that it's laying off 4,000 people because of this economic uncertainty. Also spooking the market, a company you may recognize -- Wal-Mart. Wal-Mart saying it's cutting its earnings. It's also cutting its sales outlook for the rest of the year because of the same familiar story, a challenging economy. So, you roll all this together, it just doesn't paint a good picture and you see investors running for the exits today -- Carol.</s>COSTELLO: Ok. So here is hoping for a better day tomorrow. Alison Kosik at the New York Stock Exchange. More top stories for you after a break. We'll be back.
