LONDON — Amid concerns over slower global growth rates, a slump in commodity prices, the ongoing crisis in Greece and worries about the sustainability of China's juiced stock markets, the week ahead is packed full of potentially market-moving news.

Faced with these concerns and mixed results from the company earnings season so far, the Dow Jones industrial average fell almost 3% last week, while the S&P 500 slid 2.2% and the Nasdaq fell 2.3%.

This coming week, investors will need to navigate a busy flow of corporate and economic news.

The US Federal Reserve meets Tuesday and Wednesday, with its statement on monetary policy due on Wednesday afternoon.

Earnings are expected from many of the world's biggest companies including oil majors Exxon Mobil and Chevron, Facebook, Twitter, Baidu, Fiat Chrysler Automobiles, Volkswagen and Deutsche Bank.
