European stock benchmarks were mixed  on Monday,  as M&A excitement calmed nerves following the attempted coup in Turkey over the weekend.

The FTSE 100 was recently up 0.45 at 6,699.43. In Frankfurt the Dax edged 0.04% higher to  10,071.20 and in Paris the Cac 40 was down 0.09% at 4,368.36. But Turkey's BIST 100 index was down 5.51% at 78,260.75 as President Recep Tayyip Erdogan set about clamping down on his political enemies after the weekend coup attempt left close to 300 dead.

S&P 500 mini futures were recently up 0.29%.

ARM Holdings (ARMH)  was up 42.5% in London after the chipmaker agreed to a 1,700 pence-per-share takeover offer from SoftBank Group (SFTBF) that values its stock at £24.3 billion ($32.1 billion). The stock instantly rose well above the offer price at 1,750 pence, but was recently just below at 1,694 pence.

The takeover offer fanned excitement that a weaker pound - which has fallen 11% against the dollar since the June 23 Brexit vote- will spur M&A.

Also in London, chip designer Imagination Technologies, a one-time Apple (AAPL) - Get Report target, was up almost 10%, while another chipmaker,  Infineon Technologies, was up about 2.4% in Frankfurt.  Dialog Semiconductor was up well over 4% in Frankfurt, while in Zurich AMS was up 3.6%.

But Norway's Opera Software (OPESF) fell almost 15% and was recently down 10% after it agreed to a dramatically curtailed, $600 million asset sale to Chinese investors after a $1.2 billion takeover collapsed after months in limbo.

Travel stocks declined after the failed coup in Turkey over the weekend. Package tour operator Thomas Cook was recently down 2% in London, while Tui was down about 2.4%.

But airline stocks were higher, with International Consolidated Airlines, the owner of British Airways and Iberia, up close to 4%. That made it the second-biggest gainer on the FTSE 100 after ARM.

Miners were among the worst performers on the FTSE 100. Rio Tinto (RIO) - Get Report  , BHP (BHP) - Get Report and Anglo American all release updates this week. Glencore recovered from early losses to trade only marginally lower after Credit Suisse downgraded the stock to neutral from outperform.

The pound was up 0.51% against the dollar at $1.325 after weekend news that Australia wants a free trade deal with the U.K.

But ten-year U.K. government bond yields were recently down 2 basis points at 0.81%.

Brent crude was recently down 1.03% at $47.12.
