Why is Robert Half International (RHI) stock up today?

Robert Half International shares climbed 12.61% to $39.74 — up from a previous close of $35.29 — driven primarily by a Wall Street analyst upgrade. BMO Capital upgraded the stock to Outperform from Market Perform and raised its price target to $47 from $45, a vote of confidence that sent buyers into the stock and pushed it toward its intraday high of $39.88.

The upgrade arrives at a meaningful moment. Robert Half had sold off sharply after its most recent quarterly earnings report, when investors reacted negatively to weaker-than-expected guidance despite the company posting a slight beat on earnings per share ($0.26 actual versus $0.258 estimated). That post-earnings dip appears to have set up the valuation argument that BMO and other analysts are now making — one Simply Wall St. analysis circulating this week suggested the stock may have been as much as 44% undervalued following that earnings reaction.

A broader thematic backdrop is also supportive. A news item published Sunday noted that large employers are rethinking artificial intelligence's limits and resuming hiring of workers who can operate alongside the technology — a dynamic that, if it broadens, could benefit specialized staffing firms like Robert Half directly. That narrative counters a fear that AI-driven automation would structurally reduce demand for the kind of professional and finance talent Robert Half places.

The overall market provided little additional lift today: the S&P 500 was essentially flat (+0.02%) while the Nasdaq 100 (tracked by QQQ) slipped 0.31% amid a chip-sector selloff ahead of the Federal Reserve's policy decision and major technology earnings later this week. Robert Half's large move was therefore driven by its own specific catalyst rather than a broad market tailwind. The stock's market capitalization stands at approximately $4.07 billion.
