Nokia (HEL:NOKIA) share rally may account for about 40% of Helsinki index move
Nokia Oyj rose 4.46% to 11.72 euros by 12:57 EEST in Helsinki on Tuesday, while the OMX Helsinki 25 was up 1.10% at 6,218.18. Nasdaq Helsinki was open for normal trading; Nasdaq lists Helsinki equity hours at 10:00-18:30 local time and does not list June 30 among 2026 Helsinki closure days. The cleaner angle is index math. OMXH25 is a 25-stock, euro-denominated, capitalization-weighted price index, and Nasdaq caps any one company at 10%. At that cap, Tuesday’s Nokia move would add about 0.45 percentage point to the benchmark, or roughly 41% of the index’s 1.10% rise. Actual live weights can differ.
