U.S. stocks rose slightly on Tuesday, beating back a volatile day thanks in part to a rise in home prices. The S&P 500 Index improved by 0.1%, the Dow Jones Industrial Average crawled ahead by 0.1% and the Nasdaq Composite was 0.2% better.

Heading into Tuesday’s trading, Autodesk, Inc. (NASDAQ:ADSK) and Splunk Inc (NASDAQ:SPLK) are on the move thanks to recent earnings reports, while the United States Oil Fund LP (ETF) (NYSEARCA:USO) should see some massive volume thanks to the decision at OPEC’s latest meeting.

Here’s what you need to know:

United States Oil Fund LP (ETF) (USO)

The USO ETF was soaring on Wednesday in the wake of a production cut agreement by OPEC’s member nations.

OPEC nations Iran, Iraq and Saudi Arabia managed to put their differences behind them and joined in a production pullback of 1.2 million barrels per day, according to a Bloomberg report. That would take daily production to 32.5 million barrels.

The news came via an unidentified delegate, as the announcement had not yet been made official.

Oil stocks and funds rebounded strongly in response to the oil bloc’s first cut in eight years. That included the USO fund of oil futures, which opened 6% higher. The move brings USO shares just above its 200-day moving average and right up against its 50-day moving average for the first time since the ETF crashed through both MAs in late October.

Autodesk, Inc. (ADSK)

ADSK was off on Wednesday after posting its most recent quarterly data late Tuesday.

The software designer reported a loss of 18 cents per share on an adjusted basis for its third quarter. The figure was narrower than the 24 cents in red ink that analysts were expecting. The earnings beat can be attributed to a rise in new model subscriptions from 168,000 to 861,000 year-over-year. Over this same period, total subscriptions surged from 134,000 to 2.95 million.

Revenue for the three-month period was off by 18% year-over-year to $489.6 million, but that still was enough to top Wall Street estimates for $476.8 million.

Meanwhile, total non-GAAP spending came in at $533 million, 2% lower than what the company spent a year ago.

However, Autodesk’s outlook wasn’t grand. The company is projecting an adjusted loss of 32 to 39 cents per share on $460 million to $480 million in revenues. Both figures are lower than analysts’ projections for 31 cents per share on sales of $488.5 million.

ADSK shares were off by about 2% in response.

Splunk Inc (SPLK)

SPLK is off to a spunky day thanks to its third-quarter report.

The big data software company beat the top and bottom lines. Splunk’s earnings climbed 140% to 12 cents per share to top the consensus estimate of 8 cents. Meanwhile, revenues grew 40% to $245.4 million, besting Wall Street predictions by $15.4 million.

For its upcoming quarter, Splunk expects revenues to be in a range of $286 million to $288 million. Full-year revenue will be in the range of $930 million to $932 million.

The company added nearly 500 enterprise customers in Q3.

SPLK stock soared 7% at Wednesday’s open.
