Major U.S. indices closed mixed on Tuesday, with the Dow Jones Industrial Average gaining 1.03% to 52,747.32 and the S&P 500 adding 0.2% to 7,428.78. The Nasdaq slipped 0.22% to end at 24,876.91.

Citadel Securities reportedly predicted the Federal Reserve could deliver a surprise 25-basis-point rate hike, while Jim Bianco noted markets were already pricing in roughly a 38% probability of such a move, suggesting the forecast was not far-fetched.

However, mainstream economists expected the Fed to leave rates unchanged, with attention focused on whether Chair Kevin Warsh would signal that future policy decisions would remain data-dependent.

These are the top stocks that gained the attention of retail traders and investors through the day.
