After some of the most turbulent market days in recent memory, the weekend can't come soon enough for many investors. Panicked selling on Monday and Tuesday gave way to a rush to buy on Wednesday and Thursday. However, there could be a sting in the tail for Friday - U.S. stock futures are signaling all three main indexes will open about 0.7% lower and European markets were weaker in morning trade.

In Asia: Chinese shares rallied for a second day and the yuan gained the most since April on speculation authorities took several more steps to prop up equities. During this week's wild ride, China became the epicenter of a global selloff, with a five-session crash starting last Thursday triggering steep losses in U.S. and European stocks - only to be followed by surges. The Shanghai Composite index closed the session up 4.9%, paring its loss for the week to just over 10%.

The Bank of Japan's key inflation gauge slumped to zero for a third time this year, heightening pressure on policymakers to offer fresh monetary support to reflate the world's third-largest economy. While Japan's core consumer price index was unchanged in July from a year earlier, other data provided a mixed picture for the start of the third quarter. Household spending unexpectedly fell, retail sales rose 0.6% from June, and the job market remained tight (job-to-applicant ratio rose to 1.21). Nikkei +3% to 19,136.

North Korean leader Kim Jong Un is calling this week's accord between the rival Koreas "a landmark occasion" for improved ties, but said it was the strength of its armed forces that made the deal possible. Officials from the two nations held three-days of marathon talks after an exchange of fire across their border, raising fresh hopes for a push to restore exchanges that had been cut off since 2010. South Korea's KOSPI Index closed up 1.6% following the news.

WTI crude is now on track for its first weekly gain in nine weeks, ending its longest losing streak since 1986. Crude futures -0.1% to $42.54/bbl.

According to forecasts from Beverage Marketing, bottled water sales volume grew at a rate of 7% in the U.S. last year to put it on pace to outsell soda by 2017.

The wholesale gallon price of water fell 25% over the past decade compared to a 33% rise in soda prices, and more companies continue to pour into the market.
