The market will fret over FQ1 numbers and FQ2 guidance, but Apple (AAPL) remains a must own. The tech giant ended the quarter with $216 billion in cash and marketable securities providing a strong cushion for any short-term weakness. The company does have nearly $56 billion in long-term debt, but the company is a cash flow machine whether it meets analyst estimates in FY16 or not. For FQ1, Apple generated operating cash flow of $27.5 billion and returned $9 billion to shareholders. With an enterprise value of $400 billion, a scenario where Apple is worth less than the current value is about impossible to make. Use any dip this week to buy stock alongside the company.
