* STOXX 600 down 0.3 pct at close
* Miners, oil firms fall
* Merlin slumps 16 pct on poor summer trading
* But Danone, Pearson up after well-received results
* Credit Suisse rises after activist investor move (Recasts, adds details and quote, updates prices at close)
LONDON/MILAN, Oct 17 (Reuters) - European shares dipped on Tuesday, falling from a four-month peak as weakness among commodities stocks outweighed gains spurred by results from companies including food group Danone and education firm Pearson.
Credit Suisse was also in the spotlight with its shares rising 1.2 percent on reports that activist investor RBR Capital has launched a campaign to break up the Swiss investment bank after building up a small stake in it.
The pan-European STOXX 600 index ended the session 0.3 percent lower, weighed down by a dip in basic resources and energy shares, while euro zone blue chips were flat.
UK's FTSE ended 0.1 percent lower following comments by Bank of England policymakers which were taken as dovish by market participants, while Spain's IBEX regained some ground with a 0.4 percent gain.
Results drove individual share price moves, with Danone hitting a fresh record high after the world's largest yoghurt maker posted a better-than-expected 4.7 percent rise in underlying third-quarter sales, helped by a strong recovery in demand for infant milk formula and water products in China.
"The third quarter brings back momentum to the investment case; this was anticipated to a certain degree but the boost from Early Life Nutrition (market) in China is clearly higher than thought," Baader Helvea analyst Andreas von Arx, who has a neutral rating on the stock, said in a note.
Danone rose as much as 2.4 percent before paring some gains.
Pearson soared 7.3 percent after predicting full-year operating profit in the top half of its forecast range, in the first positive trading news for the British education group in recent years.
Some results on Tuesday, however, disappointed.
Merlin Entertainments slumped around 16 percent, its biggest one-day loss.
The operator of tourist attractions such as Madame Tussauds waxworks reported a dip in trading in its key summer region, blaming a series of attacks in the UK and unfavourable weather.
Sartorius fell 7.6 percent. The lab equipment maker cut its 2017 profit and sales after destocking by some customers and a temporary freeze of deliveries from Puerto Rico caused by Hurricane Maria.
According to the latest Thomson Reuters Lipper report, third-quarter earnings for the STOXX 600 companies are expected to increase 5.3 percent from a year earlier. That compares to the 4.1 percent growth expected for the S&P 500.
Elsewhere, Airbus rose 4.8 percent after agreeing to buy a majority stake in Bombardier's CSeries jetliner programme. The deal would come at no cost for Airbus.
"Airbus' move is sensible and the downside is limited," analysts at UBS said in a note. (Reporting by Danilo Masoni and Kit Rees; Editing by Catherine Evans)
