Should You Buy CarMax While It's Below $45?

CarMax repurchased $201 million of shares last quarter and has a new CEO, Keith Barr, after activist Starboard Value disclosed roughly a $350 million stake and nominated two board members. Operationally, used-unit sales fell 8% and comparable-store sales dropped 9%, with net earnings down over 50% YoY; the stock is down ~46% over 12 months, trading under $45 vs a $82 52-week high, and forward/trailing P/E ratios are around 13. Q4 2025 results are due April 14; buybacks and governance changes suggest a potential turnaround but tariffs and weaker consumer demand pose material risks.

Analysis

The structural advantage is not just retail scale but the capital-light earnings optionality embedded in a large franchise network: stable F&I yields, higher reconditioning capture, and ownership of inspection/processing flow gives an incumbent the ability to compress turn times when wholesale pricing normalizes. That implies a faster EPS lever from inventory-cycle recovery versus pure‑play marketplaces that earn only transaction fees and remain exposed to capex-funded growth.

Primary near-term risk is macro-driven: credit tightening, a renewed drop in off-lease supply into wholesale channels, or tariff-driven parts inflation can erase margin tailwinds quickly; these are binary within a 3–12 month horizon and would hit ROIC and inventory carrying costs asymmetrically. Conversely, balance-sheet actions (accelerated buybacks, asset monetization, or captive finance JV) can create multi-quarter EPS uplift even with flat volumes because of share-count compression and improved capital returns.

The market is under‑prizing governance optionality: an activist can unlock value via targeted divestitures (non-core real estate, legacy wholesale assets) or a mandated capital-return cadence that materially raises returns on equity without operational improvement. That creates a skewed payoff where measured operational beats add modest upside, but corporate actions can produce >30–50% re-rating outcomes; downside is concentrated in execution failure or a deep cyclical reset in used-vehicle pricing.

Key Decisions for Investors

• Core long KMX (size 2–4% portfolio): horizon 9–18 months. R/R: target +35–50% to capture re-rating from buyback/asset actions; hard stop -18–20% if wholesale-price indicators (Manheim index or auction sell-through) roll over. Rationale: franchise economics + activist optionality with limited near-term capex risk.
• Levered bullish via options: buy 9–12 month KMX call spread sized to 0.5–1.0% of portfolio (debit-defined). Use strikes ~30–45% above where you execute to keep cost low; this leverages a successful corporate-action scenario while capping premium lost if the turnaround stalls.
• Pair trade (neutral retail exposure): long KMX / short pure-play online used-car peer (e.g., CVNA) on equal notional, horizon 6–12 months. R/R: captures structural margin differential and balance-sheet optionality—expect pair to outperform by 20–40% if incumbency wins; risk is platform recovery or faster digital adoption than anticipated.
• Event-protection collar around earnings windows: initiate or add to position and buy 3–6 month puts (20% OTM) while selling short-dated calls to finance cost. R/R: limits single-quarter downside (significant for a cyclical retailer) while preserving upside to a governance-driven re-rate.
