NEW YORK — U.S. stock futures moved lower as investor unease spread across global markets, with Dow futures falling by 394 points in response to growing geopolitical tensions.

The CBOE Volatility Index, widely known as Wall Street’s “fear gauge,” rose above 19.5, reflecting a notable increase in caution as traders reacted to uncertainty and shifting risk sentiment.

Market analysts pointed to international instability and war-related concerns as key drivers behind the sell-off. During moments like these, investors often pull back from risk-heavy positions and rotate toward assets viewed as more defensive.

While volatility is a familiar feature of global finance, the sharp drop in futures suggested that investors were closely watching the potential for broader fallout in the days ahead. Sentiment appeared fragile, with markets responding not only to current developments but to the possibility of escalation.

The next trading sessions are expected to provide a clearer picture of whether the decline marks a temporary reaction or the beginning of a more sustained period of market stress.

For now, the mood remains cautious, with traders, institutions, and observers tracking geopolitical developments as closely as economic signals.
