Investing.com-- U.S. stock index futures fell slightly on Tuesday evening after the S&P 500 benchmark snapped a six-day winning streak amid persistent concerns over the U.S. economy and trade tariffs.

A report that Israel was planning to attack Iran’s nuclear facilities also dented risk appetite, while oil prices sprang up on the prospect of worsening Middle East conditions.

Comments from a slew of Federal Reserve officials also showed the central bank remained largely on edge over economic and trade-related uncertainty, which diminishes the chance of any interest rate cuts in the near-term. Fed officials also warned that high trade tariffs were likely to drive up U.S. inflation.

S&P 500 Futures fell 0.1% to 5,951.25 points, while Nasdaq 100 Futures fell 0.2% to 21,413.0 points by 19:28 ET (23:28 GMT). Dow Jones Futures fell 0.2% to 42,700.0 points.

S&P 500 snaps 6-day winning streak on trade, economic uncertainty

The S&P 500 fell for the first time after six sessions on Tuesday, pressured by a pullback in technology shares after recent gains.

Investors also remained on edge over the U.S. economy after Moody’s downgraded the U.S. credit rating last week, while Congress prepared to vote on a sweeping tax cut bill backed by President Donald Trump.

On the trade front, investors were holding out for more trade deals between the U.S. and major economies. A host of reports showed high-level talks with Japan are set to resume this week, while negotiations with several other countries are ongoing.

China added to the risk aversion by warning that the U.S.’ chip export controls threatened to undermine a trade truce reached in Geneva last week.

Losses in tech stocks weighed heavily on Wall Street, as the sector also saw some profit-taking this week. Nvidia’s unveiling of a host of new artificial intelligence technology inspired limited enthusiasm.

The S&P 500 fell 0.4% to 5,940.46 points on Tuesday, while the NASDAQ Composite fell 0.4% to 42,677.24 points. The Dow Jones Industrial Average fell 0.3% to 42,677.24 points.

More retailer earnings on tap

Several major retailer stocks are set to report earnings on Wednesday, as the first-quarter earnings season winds down.

Prints from Lowe’s (NYSE: LOW ), Target, Canada Goose, and TJX (NYSE: TJX ) are due before the market opens, while cloud company Snowflake (NYSE: SNOW ) will report after the market closes. Investors are watching retail earnings for more insight into consumer spending, which was seen slowing in recent months due to pressure from trade tariffs.

Next week, AI darling Nvidia (NASDAQ: NVDA ) is set to report its first quarter earnings.
