Kevin Green says the Fed may focus more on March and April CPI data if the January numbers come in hot. However, he believes if the print comes in light and closer to the Cleveland Fed's estimates, a "risk on" mentality could return to the markets. KG races through earnings moves from Applied Materials (AMAT), Coinbase (COIN), and Arista Networks (ANET). For today's session, KG provides a wider range based off of the CPI data volatility potential. To the upside for the S&P 500 (SPX), he's watching 6900 with downside support near 6700.
