FireEye (FEYE), Palo Alto Networks (PANW) – Cybersecurity stocks are in focus after a massive cyber attack crippled more than 200,000 computers in at least 150 countries. The attack, which was first detected on Friday, involved a ransomware dubbed WannaCry and affects computers running on Microsoft’s (MSFT) Windows software that has not been updated. Hospitals, companies and governments have been impacted by the cyber attack, including French carmaker Renault SA, Chinese National Petroleum Corp. and FedEx. Cybersecurity stocks are moving higher on the news with FireEye (FEYE), Palo Alto Networks (PANW) and Proofpoint (PFPT) all posting gains. PureFunds ISE Cyber Security ETF (HACK), with top holdings that include FireEye, Qualys (QLYS), Imperva (IMPV), Gigamon (GIMO), and Symantec (SYMC), is up 3.4% as of 11:30 a.m. ET Monday.

Tesla (TSLA) – Morgan Stanley (MS) analyst Adam Jonas is changing his tune when it comes to Tesla. Jonas downgraded the electric carmaker to equal weight from overweight while reaffirming his price target of $306 per share. Jonas cited increased competition from Apple (AAPL), Amazon (AMZN), and Alphabet (GOOGL) as his reason for the downgrade. Tesla’s stock is up more than 48% since January 1.

JCPenney (JCP) – Baird cut its rating on the department store chain to neutral from outperform and lowered its price target by $3 per share to $5. The firm’s move comes after JCPenney reported a widening loss and weaker-than-expected first-quarter sales on Friday. The company said same-store sales declined 3.5% during the quarter, more than the 0.6% drop analysts were forecasting.
