Agilent Technologies rises after FDA approves its PD-L1 companion diagnostic test for multiple gastrointestinal cancers, adding to an analyst price-target upgrade and a broadly positive market day.

What happened

Agilent Technologies is trading at $135.20, up 0.87% on the day, with the dominant catalyst being the FDA's approval of its PD-L1 IHC 28-8 pharmDx assay as a companion diagnostic — a test that helps doctors identify which patients with esophageal squamous cell carcinoma (ESCC), gastric, gastroesophageal junction (GEJ), and esophageal adenocarcinoma cancers may be eligible for Bristol Myers Squibb's immunotherapy drugs Opdivo or Opdivo Qvantig. Companion diagnostic approvals are commercially meaningful for Agilent because they embed the company's test into the standard-of-care workflow for those cancer types, generating recurring diagnostic revenue tied to patient treatment decisions.

Adding to the positive tone, Baird raised its price target on Agilent to $160 from $158 on July 13 while maintaining an Outperform rating, signaling continued analyst confidence in the company's outlook. That followed a recent earnings quarter in which Agilent reported EPS of $1.49 against an estimate of approximately $1.41, and revenue of $1.83 billion. The company's trailing earnings growth stands at 60% year-over-year, with revenue growing 10% and a forward P/E ratio of 20.4, suggesting the market is pricing in continued improvement.

Technical analysis coverage from ChartMill also highlighted Agilent today, noting an 8/10 Technical Rating and 9/10 Setup Quality, describing the stock as in a solid uptrend with a tight consolidation near a resistance zone. While technical commentary does not drive fundamentals, it can attract additional attention from momentum-oriented market participants.

The broader market is providing a supportive backdrop, with the S&P 500 (^GSPC) up 0.38% and the Nasdaq-100 (QQQ) up 1.12% on the day. Macro data this week included CPI figures released July 14, with Core CPI year-over-year coming in at a forecast 2.8% versus the prior 2.9%, a modest cooling that has generally been welcomed by equity markets. Agilent currently carries a market cap of approximately $38.2 billion and a trailing P/E ratio of 27.1.

As of midday July 15, Agilent's stock has traded in a range of $132.89 to $135.80. The FDA companion diagnostic approval anchors the day's move, with the analyst price-target increase and a constructive market environment serving as secondary supports.

What did analysts say about Agilent stock recently?

Baird raised its price target on Agilent to $160 from $158 on July 13, while maintaining an Outperform rating. The adjustment came after Agilent reported earnings per share of $1.49 for its most recent quarter, above the estimate of approximately $1.41, on revenue of $1.83 billion.

Is the whole market up today or is it just Agilent?

Both are contributing: the broader market is also positive, with the S&P 500 up 0.38% and the Nasdaq-100 up 1.12% on the day. However, the FDA companion diagnostic approval and the analyst price-target increase are specific catalysts for Agilent beyond the general market tailwind.
