Why Is Moderna (MRNA) Stock Up 6.95% Today, Oct 5? Nasdaq-100 Inclusion and Phase 3 Melanoma Data Anticipation Lift Shares

Moderna shares surged on positioning ahead of its Oct 9 Nasdaq-100 inclusion, which can trigger near-term passive index rebalancing flows, and on anticipation of detailed Phase 3 melanoma data at ESMO later in October. The move appears more flow-driven than fundamentally repriced, increasing sensitivity to post-inclusion demand fade and event-risk around the oncology readout. Elevated momentum also raises near-term volatility around key technical levels.
