Will the Federal Reserve hand Wall Street a trick or a treat? Investors are abuzz about December's meeting and if an interest rate hike will happen then. The Board Governors clearly left that option on the table at its meeting this week. Starbucks (SBUX) says revenue was up 18% in the 4th Quarter. Sales at the coffee giant was higher as well. Profit, though, came in lower than expected. The coffee giant, however, spent a lot of money in the quarter rolling out its mobile ordering and payment app but that is showing growth. LinkedIn (LNKD) is also seeing growth in mobile as well as overseas. The professional online network has spent heavily this year to boost its appeal among corporate customers and overhaul its mobile presence. LinkedIn posted a smaller than expected loss and raised its financial forecast for the year.
