** RBC upgrades Finnish refiner Neste NESTE.HE to "outperform" from "sector perform", citing "unique" positioning in both oil and renewable products
** Upgrade is driven by diesel/jet price surge and refining margin strength following Iran-related disruptions, the broker says
** Renewable diesel insulated from crude volatility; ~60% of 2026 volumes locked in on stronger diesel-linked pricing
** Refining segment benefits from high margins and low exposure to Strait of Hormuz, RBC adds
** Neste shares are up around 7% in afternoon trade
