Meanwhile, economists surveyed by had expected the figure to come in at 351,000.

According to an economist quoted by The Wall Street Journal, "The drop in claims reinforces our view that the sudden weakening in the data in March was more technical than fundamental, likely due in part at least to the swing in the weather to colder-than-usual from milder-than-usual earlier."

Earnings season is also exerting its influence on the market today, as a number of bellwether companies reported their financial results from the first three months of the year. The industrial conglomerate 3M (NYSE:MMM) came in below expectations, with earnings per share of $1.61, versus the consensus estimate of $1.65.

The oil giant ExxonMobil (NYSE:XOM) is also seeing its shares fall despite beating bottom-line estimates. For the quarter, Exxon earned $2.12 per share. Analysts polled by Thomson Reuters had forecast earnings of $2.05 per share. Investors' discontent, in turn, is stemming from the company's falling revenue. In the same period last year, the company reported $124 billion in total revenue and other income. This year, it reported only $108 billion.
