Stock Market Update

[BRIEFING.COM] The S&P 500 (-0.4%), Nasdaq Composite (-0.6%), and DJIA (-0.2%) are moving lower this morning as geopolitical volatility takes center stage after last week's rally. The Russell 2000 (+0.1%) and S&P Mid Cap 400 (+0.3%) are modestly higher.

There are some lingering concerns after an escalation in tensions between the U.S. and Iran over the weekend. The U.S. seized an Iranian-flagged cargo ship, and President Trump threatened another wave of bombing strikes if a deal is not achieved. The major averages moved further below their baselines after President Trump told Bloomberg that it is "highly unlikely" he will extend the current ceasefire if a deal is not reached this week.

As for the stocks themselves, action is mixed at the sector level. Momentum across mega-cap and tech names has at least momentarily stalled after last week's rally, with the consumer discretionary (-1.2%), communication services (-1.2%), and information technology (-0.6%) sectors among the worst performers. Cruise lines, airlines, and other oil-sensitive pockets of the market are also underperforming.

However, the broader market is showing resilience, with the S&P 500 Equal Weighted Index (-0.2%) modestly higher, suggesting that investors remain confident a more durable ceasefire agreement will eventually be reached.
