Warren Buffett Passed on This Stock. Greg Abel May Not Wait Any Longer.

The article says Berkshire Hathaway (BRKA, BRKB) sold all Costco Wholesale (COST) shares in 2020, and that Warren Buffett later called the exit “probably a mistake,” citing Costco’s subsequent rise. It highlights Costco’s fiscal 2026 Q3 net sales of $69.15B (+11.6%) and net income of $2.19B, plus July 2026 sales growth and renewal rates near 90% worldwide.

Decision brief

The 30-second read

$COSTBullishLow
01

Why it matters

For COST, the actionable content is the operating update: sales growth, comparable sales, digital growth, and high renewal rates. For BRKB, the only concrete items are historical (2020 sale, 13F absence) plus editorial speculation about future ownership.

02

Market read

Traders get a fundamentals-focused snapshot of Costco’s member economics and growth, but the Berkshire angle is speculative and not a new corporate catalyst.

03

What to watch

The text does not address gross margin trends, wage/benefits inflation, inventory pressures, or gasoline mix impacts beyond excluding gasoline for comps.

Relevance 4/10Novelty 3/10Timing: today’s read-through on Costco’s latest sales and renewal disclosures

Background

The article revisits Berkshire’s prior Costco exit and argues Greg Abel may be more willing to revisit similar durable consumer franchises.

Company-level read

Ticker impact

$COSTBullishMedium confidence
Context

Costco reported fiscal 2026 Q3 net sales up 11.6% and July four-week sales up 10.7%, plus renewal rates of 92.3% in the U.S. and Canada.

Expected impact

Moderately positive bias for near-term sentiment, but no new catalyst beyond already-stated sales/renewal disclosures.

Evidence & confidence

The text provides specific operating metrics (sales growth, comps, digital growth, renewal rates) that can influence valuation expectations, yet it is framed as an opinion on Berkshire rather than a fresh corporate action or guidance change.

Market effects

Reinforces the defensive, subscription-like model in retail warehouse clubs, potentially supporting the group’s sentiment.

Highlights U.S. comps strength (U.S. comps up 6.9%) alongside global growth.

Points to worldwide renewal resilience (89.8% worldwide) and digital penetration growth, relevant to global consumer demand narratives.

Counterpoint

Strong renewal rates and comps may already be priced in; the article’s Buffett/Abel framing could distract from potential margin or competitive risks not discussed here.
