Best Buy: the structural short
The market is treating a Nintendo Switch 2 launch as the start of a turnaround. It's masking the fact that underlying comps are flat-to-negative, and the structural problems behind them are getting worse, not better.
Best Buy is a compelling short. Near-term earnings face downside risk on top of a business model in structural decline: an attractive setup for a company with moderate short interest of ~8%.
The recent 2Q26 earnings beat has triggered a sentiment rebound, with investors extrapolating a one-off gaming release as a genuine inflection. The data does not support that conclusion.
The three pillars
Comps are not inflecting
The Switch 2 launch flattered the print; underlying demand is still deteriorating.
The Nintendo Switch 2 launch contributed an estimated ~2% to 2Q26 comp growth, implying underlying comps were flat to negative. Foot traffic data, web traffic, and credit card spending all point to continued weakness. Consensus expectations of 2–3%+ comp recovery are unlikely to materialise.
Margins are structurally impaired
The differentiation that justified the premium has been cost-cut away.
Best Buy's competitive edge: in-store expertise and Geek Squad has been gutted. Vendors now charge Best Buy at least 10% higher prices than Walmart. High-margin profit pools (warranties, credit cards) have collapsed to less than half their FY2017 levels. Discount intensity is at its highest since 1Q20, yet comps remain negative. That combination: more discounting and weaker comps are signs of a structural issue and a margin trap.
The strategic pivot accelerates the decline
Marketplace and ads is the wrong fight against the wrong opponents.
Rather than reinforcing its position as a premium electronics retailer, Best Buy is shifting toward marketplace and advertising, competing directly with Amazon and Walmart on price and scale. It is a battle Best Buy cannot win, and the pivot signals management has run out of options inside the core business.
The numbers
My model forecasts gross margins falling toward 21% and operating margins below 4%, well below consensus expectations of stabilisation at 22.5% gross and 4.2% operating.
What to watch
- Catalyst (gets the short paid): 3Q26 print without the Switch 2 tailwind; holiday discounting depth.
- Disconfirming evidence: Vendor pricing parity returning to Walmart levels; Success in 3P marketplace sales driving higher margin advertising growth.
- Risks to the thesis: A faster-than-expected hard refresh cycle, significant rebound in consumer wallet; sustained gaming hardware launches in 2026.
