Iran war news continues to spur significant moves
The stock market continued to see volatile moves in conjunction with developments connected to the outlook on the Iran war. Stock valuations for some growth-dependent tech stocks were under pressure early in the day due to news that the U.S. was taking steps to block the passage of ships through the Strait of Hormuz, but bullish momentum strengthened as the day progressed. The turnaround was driven by President Donald Trump's statement that Iranian officials had called to restart negotiations on a peace deal.

Key Data Points
What's next for Palantir?
The Iran war has been a major source of market volatility since it kicked off at the end of February, and developments in the conflict will likely continue to play a big role in near-term valuation moves. In addition to higher energy and materials sourcing prices connected to the war.
While Palantir is a leading provider of defense software and analytics services, macroeconomic risks and the company's growth-dependent valuation have exposed the stock to war-related downside valuation pressures. In addition to macro dynamics connected to the war, perceptions regarding Palantir's competitive positioning in relation to Anthropic will likely continue to play a significant role in shaping the stock's near-term performance.
