U.S. equity futures fell slightly on Tuesday night after stocks continued their rally from the previous session. However, recession fears and concerns about an inverted yield curve were fuelling investors to continue watching developments in Ukraine.

Futures that are tied to Dow Jones Industrial Average fell 50 points or 0.1%. S&P 500 futures fell 0.1% and Nasdaq Composite futures lost 0.2%.

In regular trading, the Dow added 338 points, or 0.97%, and the S&P 500 rose 1.23% – both for their fourth straight day of gains. The Nasdaq Composite gained 1.84%. It is currently less than 10% away from its historic record.

CNBC spoke with Stephanie Lang, Homrich Berg’s chief investment officer.

It has been a pleasant ride,” she said. “But, I would not get too comfortable for this year because I believe we will continue to experience a lot more volatility.”

The bond market was all eyes on Tuesday, as U.S. Treasury yields of the 5-year and 30-year Treasury were released inverted Monday for the first time since 2016. This inversion was historically a signal of coming recession. However, it wasn’t a reliable indicator when that would happen. Investors largely ignored the inversion.

Main yield spread traders observed that the rate between the 2-year & 10-year rates was close to inverting on Tuesday. However, they were still positive.

Lang stated that “the big news right now is the possibility of a recession at any time.” The yield curve will invert once the yield curve is normal. You won’t experience a recession on average for 17 months. The recession risk in the future is higher than usual. But, our antennas are already up.

Investors continued to follow the conflict in Ukraine. Hope for a potential ceasefire helped investor sentiment, after Russian Deputy Defense Minister Alexander Fomin said the country will “drastically” reduce military activity near the Ukrainian capital Kyiv.

The benchmark oil in the United States, West Texas Intermediate, fell briefly below $100 per barrel, before recovering.
