Jeremy Glaser: Earnings continue in full force this week.

Apple sent shock waves through the market earlier this month when the iPhone maker issued revised revenue guidance on the back of weakness in China. They will release full results on Tuesday, and Abhinav Davuluri sees shares as undervalued today.

Analyst R.J. Hottovy thinks Amazon is also undervalued ahead of its earnings report. He believes the disruptive firm will keep finding new sources of cash flow and continue to grow at an impressive clip, even if profitability won't always be predictable.

Microsoft has been on a roll recently, reporting broad-based strength across its businesses. Analyst Andrew Lange sees Office 365, Azure, and LinkedIn as major drivers with contributions from Xbox gaming, Surface, and Dynamics. Shares are currently trading at a discount to Lange's fair value estimate.

Our long-term view on Facebook remains bullish, despite the recent string of bad headlines. Ali Mogharabi is confident the firm will maintain its competitive advantages and remain one of the premier digital advertising players. They report on Wednesday.

Other earnings this week include McDonald's, oil majors Chevron and Exxon Mobil; Visa and Mastercard; telecoms Verizon and AT&T; Merck, Caterpillar, and 3M.
