LONDON (Reuters) - After years when European companies have attracted stock investors by scoring sales to China or Brazil, share buyers are growing cautious.
For investors in developed market shares, especially in Europe where domestic demand has been particularly weak, companies with exposure to emerging markets have shown welcome resilience. The trend has also been visible, if less pronounced, in the United States.
But the popularity of such bets has pushed up share prices to levels which analysts say no longer reflect the risks, which in turn have grown. Chinese factory activity, for example, slumped to near stagnation levels last month.
The MSCI Europe with EM Exposure index is down around 8 percent so far this year, exceeding a 2 percent fall on the broad European gauge but losing only half as much as emerging markets themselves - a disparity that Goldman Sachs reckons leaves it vulnerable to deeper falls.
"A lot of these companies have become vulnerable in the short term," said Peter Oppenheimer, chief global equity strategist at Goldman, which recommends selling a basket of EM-focused companies against the STOXX Europe 600 index.
He cited a deteriorating trend in some commodity-related sectors and a rise in consumer staples shares to quite expensive levels.
The trend also holds in the United States, where the MSCI index of EM-exposed U.S. companies has underperformed the broader U.S. market - albeit to a lesser extent, given a stronger domestic economy.
The chance of a prolonged emerging markets rout, meanwhile, has deepened with the U.S. Federal Reserve signalling it will soon scale back the measures that have held down interest rates and encouraged investors to pursue higher-risk markets.
"Before, when it was relatively broad-based, you could almost pick any European company ... Now you are getting a (more) discerning consumer coming through," said F&C fund manager Mark Nichols.

Meanwhile EM exposure is prompting analysts to downgrade companies such as British American Tobacco
The valuation approach casts the spotlight on materials - one of the cheapest sectors in Europe and with the second highest exposure to emerging markets after technology.
Here, though, analysts see a reason for the cheapness, arguing that emerging markets like China are moving away from government-fuelled industrial expansion into a consumer-led one.
Autos - favoured by Goldman - and food and staples retail could be safer bets, while still making more than a fifth of their revenues in emerging markets and trading at less than 10 times expected earnings for next year, according to Starmine.
In contrast, household and personal products, with similar levels of EM exposure, trades on 19 times earnings, followed by semiconductors, with a quarter of sales in developing countries.
Choosing the right emerging market also matters, with ING Investment Management highlighting Taiwan as offering "good exposure to steady growth" while others cited South Korea for its global exposure combined with a current account surplus.
In the past, Fed tightening caused most problems for states with high external debt. This would include Venezuela and some Eastern European countries, according to Capital Economics.
The last big sell-off knocked emerging market shares down by around 40 percent in 2000-2001. In Europe the rout started about a month later and lasted nearly twice as long, taking almost 70 percent off the value of STOXX 600.
"Emerging markets have always been the litmus test for big trends in financial markets," said Stewart Richardson, chief investment officer at RMG. "We worry that the recent volatility in EM is a sign that the four-plus year trend since the lows in 2009 is being put to the test."
