The low euro is boosting revenue at LVMH Moët Hennessy Louis Vuitton and Kering SA, France's two luxury juggernauts. But under the veneer of growth lie lingering problems--uncertainty about flagship brands and an even greater slowdown in demand from their all-important Chinese customers.

Both companies will report their half-year results this week, and the weak euro is expected to make sales figures glitter with double-digit growth.

That is a feat in today's tough economic time, with a sluggish Europe still reeling from the Greek debt crisis and stalling economies in China, Russia and Brazil, countries whose newly minted rich were huge drivers for growth in past years.

Still, France's two leading luxury names, which each own a multitude of labels that sell expensive handbags, jewelry, fashion and liquor, are facing some major hurdles. Their large megabrands--Louis Vuitton, in the case of LVMH, and Gucci over at Kering--are each in the process of revamping after having lost their luster in recent years as overexpansion and a reliance on logo-driven products turned off consumers. And some industry experts warn that Chinese customers--a major portion of the brands' clientele--will scale back their purchases as the stock market crash of the past month curbs their spending.

The euro, for now, can hide some of these risks. Kering, which owns Gucci, Bottega Veneta and Yves Saint Laurent, is forecast to post revenue growth of 12% when it reports its results on Monday, according to a FactSet poll of 30 analysts. LVMH, which holds a portfolio that includes Louis Vuitton, Moët et Chandon and Bulgari, is expected to show a 16% increase in sales when it announces its results on Tuesday, according to 34 analysts surveyed by FactSet.

The low euro helps in two ways. Sales of diamond-crusted watches and crocodile-skin bags that were rung at registers in countries outside of Europe count for even more when translated into euros. Also, the low currency boosts sales in Europe as tourist shoppers--particularly those from China--make the voyage to take advantage of better deals. Due to currency fluctuations, import duties and sales taxes, some luxury items cost almost twice as much in China than they do in Europe.

Neither LVMH or Kering would comment on the foreign-exchange effects on their businesses.

Last week, Hermès International SCA, the French maker of the coveted Birkin and Kelly bags, illustrated the powerful effect of the low euro: Its sales were up 21% over the first six months of the year, but once the effect of currency was stripped away, growth was a more modest 9%.

Industry experts and investors will be listening closely this week for clues on the progress at Gucci and Louis Vuitton, and whether recent changes in leadership are translating to higher sales.

Kering's Gucci replaced its chief executive and its chief designer last winter in a bid to reinspire the struggling brand, which has seen its sales dip since 2013. But analysts say it will take at least a few more months before the new management can build buzz among fashionistas. Antoine Belge, a luxury analyst at HSBC, said in a recent note he is expecting Gucci sales to return to growth only in the fourth quarter of this year.

Meanwhile, LVMH's Louis Vuitton, the world's largest luxury fashion label, is further ahead in its own revamp. The brand hired Nicolas Ghesquière in November 2013 to succeed Marc Jacobs as creative director. Mr. Ghesquière's designs, along with investments in marketing and stores, are making an impact, says Luca Solca at Exane BNP Paribas.

"Louis Vuitton results will probably be better than most were expecting, " he predicted. "The brand has been updated and the consumer appeal has improved."

Still, luxury-brand revamps won't help if the industry's top customers--China's rising wealthy class--stop buying. They already have in their home country because of the continuing Chinese government crackdown on gift-giving and corruption, says Philip Guarino at China Luxury Advisors, a retail consultancy firm.

Moreover, the recent stock market crash in China is causing a "big-time shock in consumer confidence," he said. While the traveling Chinese will continue to make their purchases abroad, enticed by lower prices in Europe and elsewhere, he predicts high-end brands to see even fewer sales within mainland China. Louis Vuitton has 50 stores in China while Gucci has 70, according to their websites.

"The big luxury brands are way overexposed in China, with too many stores and too much in fixed costs," he said. "They need to downsize in China."
