RBC Capital Markets has made a single change to its ten-stock UK small and mid-cap (SMID) portfolio, swapping out homewares retailer Dunelm Group PLC (LSE:DNLM) for Oxford BioMedica PLC (LSE:OXB), the Oxford-based gene therapy manufacturer.
It rates the latter 'outperform' with a price target of 1,170p against a current price of 602p, implying a 94% total return.
The bank's quarterly SMID Focus report is dominated by analysis of how the ongoing US-Israeli conflict with Iran is reverberating through commodity markets and reshaping the investment case across sectors from building materials to utilities.
Since the last portfolio update in December, the Top 10 list has fallen 0.6% in absolute terms but risen 2.2% relative to the FTSE 250 index.
Since the list's inception in May 2020, it has returned 118% against 53% for the FTSE 250. On a 12-month forward view, RBC forecasts an average implied total return of 54% across the ten names.
The bank's analysts argue that OXB's trading momentum is strong, pointing to reiterated guidance for 25-30% annual revenue growth through 2028 and a recent commercial contract with Bristol-Myers Squibb.
Valuation on 2028 estimates of 2.0x sales and 7.6x earnings before interest, taxes, depreciation and amortisation implies around three times upside to the current share price in the medium term, according to RBC.
Dunelm, the FTSE 250 homewares chain, has been moved to the bank's substitute list after falling 24% since December.
RBC cited concerns about energy costs and consumer spending, with the Iran conflict likely to sustain pressure on household disposable income. The bank continues to rate Dunelm Outperform with a 1,200p price target.
The report sets out a stark picture of the energy backdrop. Brent crude has remained above $100 per barrel since 12 March following strikes on Iranian infrastructure and restrictions in the Strait of Hormuz, through which around 20% of global oil and liquefied natural gas (LNG) cargoes flow daily.
An attack on Qatar's Ras Laffan industrial complex last week removed capacity that Qatar Energy expects to remain offline for three to five years, equating to roughly 3% of global LNG liquefaction. European wholesale power prices have risen around 25% year to date.
The European Central Bank cut its 2026 eurozone growth forecast from 1.2% to 0.9% on 19 March, citing Middle East disruption and higher energy costs.
The FTSE 250 has fallen 8% on a one-month view, underperforming the FTSE 100's 5% decline. RBC notes that earnings estimate revisions have not yet reflected the deteriorating macro environment, warning that a wave of analyst downgrades may be imminent.
