NEW YORK (TheStreet) — The earnings parade is in full swing, and there are a number of key economic data points on deck next week. Traders will be focused on the Federal Open Market Committee’s announcement Wednesday to look for more clues on the timing of an interest-rate hike, which will affect commodities, commodity-based stocks and exchange-traded funds, as well as the financial sector. Other key data due next week include the S&P/Case-Shiller Pending Home Sales, GDP, the Consumer Confidence Index, and the Chicago and Dallas manufacturing surveys. The theme so far this earnings season is the tremendous moves in names such as Google , Amazon and Netflix due to blowout quarters and strong guidance. Conversely, if companies show weak reports, such as Caterpillar’s , the market is showing no mercy, which is reflected in the stock price. All eyes will be on Twitter on Tuesday as the stock and company continue to struggle. Over the past six quarters as a public company, Twitter’s post-EPS move was 16.2%. On Wednesday, reports are due from industrial conglomerate Eaton , payment processor MasterCard and Facebook . While Caterpillar disappointed, Eaton’s management team is solid and could produce a better result. Visa blew away its quarter, and MasterCard looks to be in good shape as well, as the payment processors continue to outperform. Facebook is up 450% since it hit a low in August 2012 and is up 25% on the year as the company continues to improve on several verticals. On Thursday, energy stock Occidental Petroleum and Starwood Hotels & Resorts deliver earnings. Occidental Petroleum has been trading in sympathy with the energy sector as crude struggles to find a bottom, while trends in the travel industry remain strong.
