The S&P 500 is set to close April with its best monthly performance since 2020, driven by a broad-based rally across key sectors.

The index has gained momentum in recent weeks, with investors showing renewed confidence in the market's trajectory.

This development comes as Apple prepares to release its quarterly earnings, which is expected to be a key focus for traders ahead of the report.

The market's positive momentum has been reflected in the index's performance, with gains accumulating steadily as the month draws to a close.

Analysts suggest that the rally has been supported by a combination of improved corporate earnings and a more optimistic outlook on the broader economic environment.

The S&P 500's performance has also been buoyed by a shift in investor sentiment, with risk-on trades gaining traction in recent sessions.
