Investing.com-- U.S. stock index futures fell in evening deals on Tuesday as a rally in Wall Street, following Donald Trump’s election victory, fizzled out as caution kicked in ahead of key inflation data. 

Sentiment was also rattled by some hawkish comments from Federal Reserve officials, who warned that any increases in inflation could elicit a hold on interest rates. 

Losses in futures came after Wall Street indexes retreated from recent peaks during Tuesday’s session.

S&P 500 Futures fell 0.1% to 6,005.0 points, while Nasdaq 100 Futures fell 0.2% to 21,146.75 points by 18:38 ET (23:38 GMT). Dow Jones Futures fell 0.1% to 44,034.0 points. 

Trump-fueled rally fizzles as CPI data looms 

Investors were seen locking in some profits after Trump’s election victory sparked sharp stock gains over the past week.

This rally also appeared to have paused as investors sought more clarity on what a second Trump presidency will look like, given that the president-elect has maintained a protectionist stance towards trade and immigration. 

A Trump presidency is also expected to potentially push up inflation in the long term.

These doubts grew ahead of key consumer price index inflation data, which is due on Wednesday. The reading is expected to show inflation remained steady in October, sparking some doubts over just how much impetus the Fed has to keep cutting interest rates.

Minneapolis Fed President Neel Kashkari warned on Tuesday that any surprises in inflation could see the Fed keep rates steady in December. His comments saw traders pricing in a 59.8% chance that the Fed will cut interest rates by 25 basis points in December, and a 40.2% chance rates will remain unchanged, according to CME Fedwatch. 

The central bank had last week cut rates by 25 bps and reiterated its data-drive approach to further easing.

Wall St retreats from record highs 

Wall Street indexes fell from record highs on Tuesday as investors locked in a measure of recent gains. Caution before the CPI reading also weighed, as the dollar and Treasury yields appreciated sharply. 

The S&P 500 fell 0.3% to 5,983.99 points, while the NASDAQ Composite fell 0.1% to 19,282.76 points. The Dow Jones Industrial Average slid 0.9% to 43,910.98 points.
