Because a company can only be as strong as its customers, there's no way for tech companies to be completely insulated from broader economic events. Companies with a lot of exposure on Wall St. are going to be particularly susceptible to a slowdown, as some companies, like Cisco, have already stated that they're seeing weakness in this market. The latest to sound a similar warning is Tibco, a software provider with a lot of customers in finance. The firm described the financial sector as "notably weak" blaming it for an overall earnings shortfall. It should be noted that Tibco hasn't had a particularly stellar few years, so the company was already struggling a bit. Still, what's affecting Tibco is likely to affect a host of other related companies. Right now, there's a lot of concern about the health of the financial sector, but if troubles continue to persist, then the malaise is likely to spread elsewhere, potentially leading to spending slowdowns in other sectors.
