An unprecedented single options transaction has put Fortum in the spotlight: 60,000 of the 60,030 calls traded were the Dec 17, 2027 EUR28 call, opened with zero prior open interest while the underlying stock was at €23.99. That trade establishes a new high-water mark for call block volume in Fortum equity options and represents a large, directional wager rather than a reorganization of existing hedges or aggregated retail flow.
The mechanics are straightforward but striking in scale. At a spot price of €23.99, the EUR28 strike is approximately 16.7% out-of-the-money. For the options to expire with value, Fortum would need to rise beyond levels that neither JPMorgan nor Goldman Sachs currently list as their price targets - €24.30 and €25.50, respectively.
The context behind the trade
The timing of the block is notable. It comes on the heels of a two-day sequence that materially altered the near-term narrative around Fortum.
- Sep 9 - Fortum announced a 22-year power purchase agreement with Alphabet covering 500 MW from the Loviisa nuclear plant, priced at an estimated €80–90/MWh. That level compares to Nordic forward prices in the 50s, and the announcement produced a 15.82% one-day share-price gain.
- Sep 10 - JPMorgan and Goldman Sachs moved their recommendations upward to Neutral, with price targets of €24.30 and €25.50, respectively, having previously carried Sell/Underweight stances.
Goldman’s internal modeling noted an approximate 30% lift to EPS by 2030 and identified 5 GW of potential data-center and industrial-site optionality that is not reflected in its published target. The size and tenor of the option position suggest the buyer may be valuing that kind of upside optionality directly.
Option-market signals
Options-market metrics around the trade reinforce a directional, call-biased picture. Three-month implied volatility sits at 35.24%, up 0.60 percentage points, reflecting a rising premium as market participants price more event risk. The 90/110 skew inverted, down 0.30 percentage points after a 1.23 percentage-point decline, indicating the call wing is gaining demand relative to the put wing. Put volume for the period was modest at 1,480 contracts, suggesting there was little uptake in protective put buying tied to this move.
In a typical post-gain environment, elevated put demand often keeps skew positive as traders seek protection. Instead, the observed skew change and the concentrated block point to buyers aggressively bidding calls rather than purchasing puts for downside protection.
Bull and bear interpretations
On the bullish side, the EUR28 strike reflects an expectation that market pricing still understates long-term nuclear and data-center power economics. Goldman explicitly flagged site optionality amounting to 5 GW that lies outside its target, while JPMorgan’s FY28 EPS estimate sits materially above consensus, which could be read as evidence of unpriced upside.
On the defensive side, the fact that the Dec 2027 calls had zero prior open interest means this is a newly initiated position; it could therefore represent a sophisticated hedge of an existing short exposure rather than a pure directional long. Both sell-side revisions landed at Neutral rather than Buy, and JPMorgan noted that risk-reward is now balanced, tempering a fully optimistic interpretation.
Why December 2027?
The chosen expiry brackets several company-specific milestones: the Loviisa life-extension timetable, the expected ramp of Google’s Finnish data-center investments scheduled around 2027-2028, and the timeframe over which Goldman expects its modeled EPS gains to materialize. The position appears structured to capture a structural re-rating over multiple catalytic developments rather than a short-term spike.
