European benchmarks rose sharply Tuesday after a volley of better-than-expected corporate earnings reports pushed index bellwethers higher across the continent.

Germany's DAX index led the charge with a 0.99% gain, quoted at 12,239, a little more than an hour off from the close. The CAC 40 index followed closely behind it, with a 0.80% gain, to 5,132.

In London, the FTSE 100 added 0.70% and was quoted at 7,422, while its mid-market sibling, the FTSE 250, was up 0.36% at 19,851. Over in Southern Europe, the IBEX in Madrid and the FTSE MIB in Milan posted gains of 0.19% and 0.90%, respectively.

In individual stocks, Rolls Royce (RYCEY) topped the FTSE 100 in London with a gain of nearly 10% after it reported a 12% increase in revenue for the first six months of the year, to £7.57 billion ($9.75 billion).

The engineering firm benefited from a 27% increase in large jet engine deliveries, which helped the firm swing from a £2.15 billion loss in the same period one year ago, to a profit of £1.94 billion in the six months to the end of June. Adjusted profits more than doubled to £287 million for the period. 

Outsourcing firm Intertek (IKTSF) was up more than 9% after it too made a mockery of analyst forecasts for revenues and earnings in the first-half, before increasing its dividend by more than 20%, thanks to a stellar performance from its third-party product-testing division. 

Auto insurer Direct Line (DIISF) and oil giant BP (BP) also both saw good gains during the session, of 5% and 4%, respectively, thanks to better-than-expected performances during the recent reporting period.  

Over in Paris, stocks benefited from building momentum in the eurozone economy, with second-quarter GDP figures showing a pickup in growth during the recent period, which helps to boost stocks like BNP Paribas (BNPQY) , Vivendi (VIVHY) and Airbus (EADSY) just as the European reporting season gets underway. 

In Frankfurt, shares of medical device maker, Fresenius (FMS)  rose more than 2% to the top of the DAX Tuesday after it said its quarterly earnings rose 19%, to €450 million ($510 million), when compared with the same period one year ago, thanks to recent acquisitions.

This is while Deutsche Lufthansa (DLAKY) and Deutsche Bank (DB) both saw gains of close to 2% for the session amid broad strength in airline stocks and from many of Europe's banks.
