* SAP gains as cloud sales boost Q1

* Luxury stocks rise after LVMH results

* Economic institutes will cut 2021 German GDP forecast -sources

April 14 (Reuters) - European stocks rose on Wednesday on upbeat earnings from software firm SAP and French luxury goods maker LVMH, while German shares lagged after sources said the country's economic institutes cut 2021 GDP forecast.

The pan-European STOXX 600 index rose 0.2%, closing just 0.2% shy of record highs, as an impressive bounce-back in sales saw LVMH scale a record highs, spurring gains in other luxury names.

Germany's DAX index ended 0.2% lower. Economic institutes will cut their joint 2021 growth forecast for Europe's largest economy to 3.7% from 4.7%, sources said, due to a longer than expected COVID-19 lockdown.

Data earlier in the day showed euro zone industrial output declined as anticipated in February, including in Germany, dampening prospects for economic growth in the first quarter.

"But underlying demand is strong and that makes us upbeat about prospects for the bloc as it reopens later in the year," said Bert Colijn, senior economist, eurozone at ING.

Germany's SAP jumped 1.1% as it raised 2021 revenue outlook higher after reporting a quarterly rise in cloud sales.

Upbeat results from big U.S. banks JPMorgan Chase, Goldman Sachs and Wells Fargo also boosted sentiment.

Earnings helped offset concerns about a potential setback to the Europe's COVID-19 vaccination program after Johnson & Johnson said it would delay rolling out its vaccine in Europe.

European stocks have notched all-time highs in recent days on hopes of a strong quarterly reporting season, as well as a rapid recovery in the global economy despite a resurgent COVID-19 pandemic.

"The economic rebound may not be as robust as expected if consumers continue to play it safe after an initial bout of reveling, which could bring company profits in below expectations, and moderate demand for riskier areas of the market," said Laith Khalaf, financial analyst at AJ Bell.

"While investors shouldn't ignore these downside scenarios, the central case remains a gradual reopening of the global economy as vaccines steadily bring the pandemic under control."

Earnings for companies listed on the STOXX 600 are expected to jump 55.7% in the first quarter, according to Refinitiv IBES data, more than the 47.4% rise forecast a week earlier.

Britain's biggest retailer Tesco fell 2% after reporting a 20% drop in full-year pretax profit, while British airline easyJet rose 5.8% after saying it expected to start to fly more from late May.

Miners gained after Goldman Sachs painted a robust outlook for copper miners, adding there is potential for re-rating stocks higher as investors increasingly seek exposure in the red metal.
