Good chart. It looks that way thanks to six reasons: Facebook (Meta), Apple, Amazon, Microsoft, Netflix and Google (Alphabet). The answer to how long U.S. stocks lead international very likely depends on how well those 6 mature tech behemoths continue growing earnings at feverish, unprecedented rates. Facebook is wobbling severely, mostly due to new Apple I-Phone privacy features, which undercut Facebook’s ad revenue, plus various expensive Meta projects with unproven revenues. Meta’s stock has fallen by half since September. Google is also heavily ad-based. Amazon’s revenues are overwhelmingly reliant on its cloud data services, not its delivery trucks. Netflix? Uh oh. Earnings were bad and the stock has fallen by half since November. How much more market share is there to be gained by the remaining 4 behemoths to drive the S&P 500 ever-higher and higher?
If anyone is comfortable things will never again change, well, I’m not.
