Why is Bio-Rad Laboratories, Inc. Class A (BIO) stock moving?

Bio-Rad closed at $386.48 on Nov 10, up about 6% from $363.50 on Oct 22. The move follows Q3 results on Nov 4 that beat estimates: non-GAAP EPS of $2.65 versus $2.23 expected, and sales of $656.4M versus $649.95M. Currency-neutral sales grew 0.7%, with Clinical Diagnostics up 2.8% and Life Science down 2.4%. GAAP results were weaker, with an operating loss of $(49.7)M linked to restructuring and impairment items, although GAAP net income was $458.6M. Management affirmed FY2026 sales guidance of $2.506B-$2.596B, but the midpoint of $2.551B is slightly below the $2.588B consensus. RBC raised its target from $390 to $440 on Nov 5 and kept Outperform, about 14% above the Nov 10 close. The stock sold off to $369 on Nov 5 on 434K shares despite the raise, then rebounded. On Nov 9 it traded on 547K shares, set a new 30-day high of $394.73 and closed at $388.31 near the session high. Positives are the earnings beat, the analyst upgrade and improving price momentum. Risks are soft currency-neutral growth, Life Science weakness, the guidance midpoint below consensus, and GAAP losses.
