NEW YORK (CNN/Money) -
U.S. stock markets floundered around the breakeven point early Friday as investors showed disappointment about some tech earnings and scrutinized still expensive oil.
After 10 minutes of trading, the Dow Jones industrial average (down 0.92 to 10,376.60, Charts), the Standard & Poor's 500 (down 0.53 to 1,131.52, Charts) index and the Nasdaq composite (down 0.22 to 1,983.45, Charts) all traded just below unchanged.
The last trading day of what has been a pretty lackluster week is bound to be fairly volatile. Friday -- which happens to be the last trading day of spring -- is a "quadruple witching" day, when stock index futures and options, and individual stock futures and options all expire simultaneously.
Among early movers, two tech companies offered mostly upbeat earnings, but saw investors sell their stocks on expectations for even higher results.
Red Hat (RHAT: down $2.39 to $20.00, Research, Estimates) tumbled after the Linux distributor reported higher quarterly earnings late Thursday on revenue that missed analysts' estimates.
Adobe Systems (ADBE: down $0.69 to $43.92, Research, Estimates) edged lower. The graphics design chipmaker reported earnings late Thursday of 44 cents per share, up from 27 cents a year earlier and 2 cents more than expected. However, shares declined, as some investors had hoped the company would post even more bullish results.
The one economic report released Friday morning showed the U.S. current account deficit widened more than expected in the first quarter, due to the increasing gap between imports and exports.
Oil prices continued to hover near two-week highs. Brent crude oil futures rose 7 cents to $36.28 a barrel in London. Among other commodities, COMEX gold rallied $5.90 to $395.40 an ounce.
Treasury prices were flat, with the 10-year note yield at 4.68 percent. The dollar was a bit weaker versus the yen and euro.
In international trade, Asian markets closed mostly lower Friday, while European markets were mixed at midday.
