Castellum and Fabege are two of the most followed commercial real estate companies on Nasdaq Stockholm — and they offer meaningfully different risk and return profiles within the same broad real estate cycle. Castellum is diversified across Sweden and Denmark; Fabege is concentrated in premium Stockholm locations.
Swedish listed real estate was among the hardest-hit sectors globally when rates rose. Castellum's share price fell approximately 65% peak-to-trough between 2021 and 2023. Fabege fell approximately 55%. The primary driver was the mathematical compression of property values when discount rates rise — not a collapse in rental income, which remained broadly stable for quality commercial properties.
This distinction is important: the correction was a valuation reset, not an earnings collapse. Rental income held up because Swedish commercial lease contracts typically run 3–5 years with annual CPI indexation — providing inflation protection that pure bond investments lack.
Castellum went through significant governance change in 2022 following the controversial attempted merger with Heimstaden. A new management team refocused the company on its core competencies — commercial properties in Swedish regional cities and Copenhagen. A large equity raise in 2023 reduced leverage and stabilised the balance sheet. Post-restructuring, Castellum offers lower-risk real estate cycle exposure with a more predictable recovery path.
Fabege's concentrated Stockholm CBD and Solna Business Park portfolio is both its strength and its risk. Vacancy in inner Stockholm office space has remained below 5% even through the remote work disruption — suggesting structural demand for premium central locations. Fabege's development pipeline in Arenastaden adds NAV optionality that Castellum's more passive portfolio lacks.
Early cycle recovery: Castellum offers lower risk and a more reliable recovery given its diversification and post-restructuring balance sheet. Late cycle expansion: Fabege's development gains and premium positioning typically drive NAV upgrades that outperform in the expansion phase. Both should be bought when the Riksbank signals rate cuts and P/NAV is below 0.7x.
