A record-breaking July has some investors wondering if the market's due for a pullback. CFRA's Sam Stovall says while the S&P 500 and Nasdaq's recent highs are impressive, there are signs of overvaluation, particularly in tech. He notes that although the Fed held off on a rate cut, inflation concerns may keep rates steady for now. Stovall shares his take on what a winning portfolio might look like, highlighting sectors like communication services, consumer discretionary, and tech, which have historically outperformed during market declines.
