US stocks pulled back on Tuesday, led by a nearly 2% decline in the Nasdaq, following two days of gains as investors concerned about an economic slowdown looked to the Federal Reserve’s policy meeting for insights.

The tech-heavy Nasdaq Composite (^IXIC) plummeted about 1.7% as Nvidia (NVDA) shares fell roughly 3% as its annual GTC event failed to impress investors. Other “Magnificent Seven” names also dragged down the tech-heavy index. Notably, those stocks are having their worst quarter in more than two years.

The Dow Jones Industrial Average (^DJI) and S&P 500 (^GSPC) also moved to the downside on Tuesday, dropping about 0.6% and 1.1%, respectively.

Uncertainty still dogs markets as investors debate whether the sell-off that pushed the S&P 500 into correction territory is over. Traders now turn their attention to the Fed’s two-day policy meeting, which kicked off on Tuesday, for clues on the health of the economy and potential tariff risks.

Policymakers are largely expected to hold rates steady in their decision on Wednesday.
