This week will be busy on the corporate earnings front, with more than 30% of the S&P 500 reporting.

What to watch: Tech will consume most of the conversation surrounding earnings with reports from two "FANG" companies — Google parent Alphabet and Amazon — plus Microsoft, Twitter and Snap.

CEO to analysts and short-sellers: "You are messing with the wrong guy"

The CEO of mining company Cleveland-Cliffs Lourenco Goncalves lost it on a call with analysts on Friday — at one point calling out Goldman Sachs analyst Matthew Korn by saying he "can run but can't hide," and announcing he planned to "screw" short-sellers by buying back so much stock "they will have to commit suicide."

Why it matters: This is another example of the sometimes tense relationship between executives and analysts and short-sellers. Remember Elon Musk's wild earnings call earlier this year.
