Wall Street slips as tech drags, Iran peace hopes fade

US stocks slipped into the red on Tuesday, as a sell-off in technology shares offset early gains and fading hopes of a US-Iran rapprochement kept investors on edge. The S&P 500, Dow Jones Industrial Average, and Nasdaq Composite all ended the session lower, with the tech-heavy Nasdaq bearing the brunt of the decline.

Tech drags, but losses contained

The dip was modest, but the direction was clear. After opening marginally higher, the major indices reversed course by midday, with tech stocks leading the slide. Investors appeared to take profits in a sector that has powered much of the market's rally this year, while broader concerns about global growth and geopolitical tensions simmered beneath the surface.

Trading volumes were lighter than usual, suggesting that many institutional players were waiting for clearer signals before committing fresh capital. The Dow and Nasdaq each fell by less than half a percent, a sign that the sell-off was more about repositioning than panic.

Iran impasse weighs on sentiment

The optimism that briefly lifted markets last week, when Washington and Tehran hinted at possible dialogue, has all but evaporated. Reports of an impasse in negotiations over the Strait of Hormuz have revived fears of supply disruptions in one of the world's most critical oil shipping lanes. The development has kept a floor under crude prices, which extended their gains for a third straight session.

Rising oil prices are a double-edged sword for equity markets. While energy stocks benefit, higher fuel costs threaten to squeeze consumer spending and corporate margins, complicating the Federal Reserve's path on interest rates. Analysts noted that the market's muted reaction suggests investors are bracing for a prolonged period of uncertainty rather than a swift resolution.

CPI data takes centre stage

Attention now shifts to the upcoming consumer price index (CPI) report, which is widely seen as the next potential market catalyst. With inflation still above the Fed's comfort zone, a hotter-than-expected print could reignite fears of further rate hikes, while a cooler number might provide some relief to rate-sensitive growth stocks.

Economists are divided on what the data will show, and that uncertainty is reflected in the market's cautious tone. Bond yields were little changed on Tuesday, with the 10-year Treasury hovering near recent levels, as traders held off on making big bets ahead of the release.

Global cues remain mixed

Overseas markets offered little direction. European bourses closed mostly flat, while Asian shares were mixed overnight. The dollar index firmed slightly, adding to pressure on commodities priced in the greenback, though gold held steady as safe-haven demand offset the stronger dollar.

The coming days will test whether the current pullback is a pause or the start of a deeper correction. For now, the path of least resistance appears lower, but with valuations stretched and sentiment fragile, any positive surprise on inflation could quickly flip the script. Investors would do well to watch the CPI release closely, as it may well set the tone for the rest of the week.
