It's another stormy day for stocks across the world after twin surveys showed China's manufacturing sector in the grip of its worst slump in several years. China's official Purchasing Managers' Index fell to 49.7 in August from the previous month's reading of 50.0 - the weakest showing in three years, while the Caixin China manufacturing PMI showed a final reading of 47.3 in August, the lowest since March 2009. The figures detail an even sharper slowdown in the world's second-largest economy, reinforcing fears that have triggered heavy global market selloffs.

South Korean exports tanked by the most in six years in August, bolstering expectations its central bank will cut rates next week to tackle a rapidly darkening outlook. Exports fell 14.7% last month from a year before, dragged down by a heavy slowdown in China and a sharp decline in exports to Europe and Japan. The data is important as it provides the first full trade picture in the region after China's currency devaluation on August 11.

As widely expected, the Reserve Bank of Australia has kept interest rates steady at a record low 2%, stating the current stance will foster growth.

The RBA last trimmed rates in May and February.

Eurozone manufacturing growth eased last month, despite factories barely raising prices, adding to the ECB's woes as it battles to spur expansion and inflation. Markit's final manufacturing Purchasing Managers' Index came in at 52.3 in August, below an earlier flash reading that suggested it had held steady at 52.4. The figure, however, has been above the 50 mark that separates growth from contraction for over two years.

Oil prices are pulling back as investors cover short positions and take profits following an 8% rise in the previous session. The surge was fueled by a downward revision of U.S. oil output and a report that suggested OPEC may be considering cutting production. Since last Thursday, WTI crude has climbed 27.5% - the largest three-day dollar increase since February 2011 and the biggest percentage increase since August 1990 - but where is the commodity heading to now? Crude futures -2.9% to $47.79/bbl.

A tax policy advocacy group, Americans for Tax Fairness, is calling for Etsy (NASDAQ:ETSY) to be stripped of its B Lab certification unless it dismantles its offshore tax cutting structure.

Since August 10, Sprint (NYSE:S) shares have skyrocketed over 50% as Softbank upped its stake in the carrier to 82%. While more than $7B has been added in market value, Sprint's cash burn is still an issue: Cash and equivalents fell by $1.95B (compared to $799M a year ago), translating into a $2.06B balance at the end of the quarter.
