The stock market today sold off amid the hot Consumer Price Index or the CPI report. "Energy is a challenge for consumers. Overall, the stock market is still seeing challenges with inflation," says George Tsilis. How is the S&P 500 or the SPX performing amid inflationary concerns? "The Fed is further behind the yield curve right now and there may be more aggressive rate hikes. However, there could be inversions to the curve. Investors should be concerned if the 3 year rates start to move above the 2 year rates," Tsilis adds.
