Kevin Green explains that while Micron's (MU) revenue and adjusted EPS guidance exceeded expectations, the gross margin outlook is the main concern, with the company citing higher-than-expected expenses to develop new chips. Meanwhile, FedEx (FDX) is also under pressure, down 8% in pre-market, after the company reported a revenue beat but lowered its full-year EPS guidance due to continued pressure on freight traffic and volume. With triple witching today, Kevin expects a volatile session, but notes that historically, volatility tends to subside after this event.
