Investor sentiment shifts as stock market rally continues.

Despite recent gains in the stock market, investors are skeptical about the sustainability of the rally, with concerns about a possible recession and the Federal Reserve's hawkish signals. Mega-cap tech stocks have been driving much of the gains, but there are signs that the market's breadth is improving. The next test for stocks will likely be the Fed's next interest rate decision, which could trigger a market correction. However, some investors remain bullish, citing recent robust economic data and positive investor sentiment.
