Another day, another AI mood swing

Tuesday saw software stocks stage something of a rally, weirdly driven by the thing that's beaten them down for the past month: a sweep of new plug-ins from AI lab Anthropic. This time around, the market focused more on the partnerships between some of these companies and Anthropic, rather than the existential threat AI could pose. ANOTHER DAY, ANOTHER AI MOOD SWING Even though many software stocks caught a break yesterday, others affected by Anthropic's new tools were less fortunate. HR software firm Workday fell 10% overnight, with a downbeat revenue forecast aggravated by the fact that HR tasks were listed among the targets of Anthropic's new gizmo. While the broader rebound may not last, it does suggest markets remain highly sensitive to AI-related news flows. NVIDIA IN THE SPOTLIGHT The bigger AI event this week is Nvidia's earnings report due on Wednesday. The chip giant is expected to forecast a 64% jump in first-quarter revenue to about $72 billion. But the bar to impress is rising all the time, and Nvidia is facing increasing competition from the likes of Alphabet and AMD. Chinese demand may also be in focus given the recent ebb and flow of government restrictions on the sale of its top chips there. Even though Nvidia shares are only up 2% for the year so far, options markets are braced for a post-earnings swing of plus/minus 5%. The scale of the firm these days means that's a swing of about $230 billion in market cap either way. After the S&P 500's 0.77% jump on Tuesday, futures were up ahead of Wednesday's bell. Elsewhere, Asia's stocks motored higher on Wednesday amid a growing focus on what AI capex is doing for companies aiding the infrastructure buildout. Chart of the day With its earnings update due later on Wednesday, Nvidia revenue is expected to have jumped 68% to $66 billion, and analysts assume its first-quarter revenue forecast will show another 64% jump to $72 billion. The company has surpassed sales expectations for the past 13 quarters, though the scale of those beats has shrunk, competition in AI chips is rising, and the bar to impress moves ever higher. After powering much of the U.S. stock market rally for the past three years, Nvidia's stock has risen about 2% so far in 2026. GLOBAL MARKETS South Korea's Kospi benchmark, which has risen a staggering 45% already this year, rose 2%, while Japan's Nikkei gained 2.2%. That Japanese stock move was aided by another fall in the yen to its lowest in two weeks after news that Japanese Prime Minister Sanae Takaichi's nominees to two Bank of Japan board positions were seen as 'reflationists' — something of a mirror of the Fed story stateside. Meanwhile, the yuan strengthened further to near three-year highs against the dollar as German Chancellor Friedrich Merz became the latest European leader to visit China this year. The offshore yuan has now risen 3% over the past month. There were few market takeaways from President Trump's broad-brush State of the Union speech late Tuesday, but the AI theme made its way in as Trump told Big Tech companies they must build their own power plants for their data centers. Trump also promised $1,000 contributions next year to Americans not covered by 401k retirement accounts — money likely to find its way directly to the stock market.
