COST$983.86+0.4%Cap: $436.7BP/E: 51.352w: [======|----](Mar 28)
Verdict: KEEP at benchmark 2.37%
No thesis for removal. Pristine execution across every metric, tariff beneficiary vs peers, no idiosyncratic catalyst for underperformance in the 15-week window. Low QQQ beta (0.28) is a portfolio-level concern, not a stock-specific removal signal. Market consensus is correct — no mispricing identified. 37 analysts, $437B cap, zero information asymmetry.
LR 0.8 (supports KEEP). Evidence uniformly against removal. No bear thesis survives scrutiny.
Factor Profile (worldview regression, 251d daily)
| Metric | Value | Assessment |
|---|---|---|
| beta QQQ | 0.28 | Consumer staple in tech index |
| beta SPY | 0.36 | Low market sensitivity |
| beta XLP | 0.86 | Structurally a staples stock |
| beta MTUM | 0.02 | No momentum exposure |
| Idio variance | 87.2% | Clean (>75% target) |
| alpha (annualized) | +1.3% | t=0.10, statistically zero |
| Idio vol | 18.9% | Low |
| R-squared vs QQQ | 9.9% | Moves independently of index |
Rolling 60d beta to QQQ declined from 0.42 (Jul 2025) to 0.00 (Feb 2026). This stock increasingly decouples from the tech-growth index.

Income Statement (Q2 FY2026, 12 weeks ended Feb 15)
| Line | Q2 FY2026 | Q2 FY2025 | YoY |
|---|---|---|---|
| Net sales | $68,242M | $62,530M | +9.1% |
| Membership fees | $1,355M | $1,193M | +13.6% |
| Total revenue | $69,597M | $63,723M | +9.2% |
| Merch costs | $60,719M | $55,744M | +8.9% |
| SG&A | $6,272M | $5,663M | +10.8% |
| Operating income | $2,606M | $2,316M | +12.5% |
| Net income | $2,035M | $1,788M | +13.8% |
| EPS (diluted) | $4.58 | $4.02 | +13.9% |
Margin waterfall:
- Gross margin: 11.02% (+17 bps YoY; +11 bps ex gas)
- Core-on-core gross margin: +22 bps (broad-based: nonfood, food & sundries, fresh all higher)
- SG&A rate: 9.19% (+13 bps; +8 bps ex gas). Ops component flat ex gas — productivity offset wage investments + extended hours. Central +3-4 bps. Liability reserve one-time: 6 bps. Underlying SG&A +2 bps ex gas. Clean.
- Operating margin: 3.82% (+12 bps)
- Tax rate: 25.2% vs 26.2% (100 bps benefit, ≈1% EPS tailwind)
Segment Margins (Q2)
| Segment | Revenue | Op Income | Margin | YoY |
|---|---|---|---|---|
| US | $49,931M | $1,635M | 3.27% | +1 bp |
| Canada | $9,291M | $476M | 5.12% | +26 bps |
| Other Intl | $10,375M | $495M | 4.77% | +35 bps |
US margin flat. All expansion from international + FX. If dollar strengthens, this tailwind reverses. Not a risk for filtration (affects absolute return, not QQQ-relative).
Balance Sheet
| Item | Feb 15, 2026 | Aug 31, 2025 | Change |
|---|---|---|---|
| Cash | $17,383M | $14,161M | +$3,222M |
| Inventory | $18,991M | $18,116M | +$875M (+4.8%) |
| Accounts payable | $20,647M | $19,783M | +$864M |
| Deferred membership | $3,126M | $2,854M | +$272M (+9.5%) |
| Long-term debt | $5,688M | $5,713M | -$25M |
| Total equity | $32,087M | $29,164M | +$2,923M |
Net working capital in merchandise: Inventory minus AP = negative $1.66B. Costco sells before it pays. Model intact. Inventory days ≈24 vs ≈25 last year — improving turnover despite inventory build. H1 FCF ≈$4.9B.
Comp Sales Trend
| Period | Adj Comp | Traffic | Adj Ticket |
|---|---|---|---|
| Q1 FY2026 | +7.2% | +3.3% | +3.7% |
| Q2 FY2026 | +6.7% | +3.1% | +3.5% |
| Feb (4 wks) | +7.0% | +3.0% | +3.9% |
Remarkably stable. Management: "very consistent in that 6-7% range." February US traffic slightly soft due to Northeast weather (55 warehouses closed a full day), but total results unaffected. Digital comp +22.6%.
Membership Deep Dive
| Metric | Q2 FY2026 | YoY |
|---|---|---|
| Total paid members | 82.1M | +4.8% |
| Executive members | 40.4M | +9.5% |
| US/Canada renewal | 92.1% | -10 bps QoQ |
| Worldwide renewal | 89.7% | flat QoQ |
| Executive penetration | 75.8% of sales | -- |
| Membership income (organic ex fee/FX) | -- | +7.5% |
Membership growth deceleration: 4.8% vs ≈5% historical. CFO attributes to cycling strong prior-year sign-ups and fewer new market openings. Not structural. Executive upgrades +9.5% show depth of engagement.
Renewal rate decline slowing: -40 bps (Q4 FY2025) to -30 bps to -10 bps (Q2 FY2026). CFO: "may slow a few more quarters" but digital retention programs working. Driver is online member mix renewing at lower rates than warehouse sign-ups. CFO flagged explicitly in Q4 FY2025: "we do think we'll see a few more quarters of a similar type of impact." Worldwide rate held flat at 89.7%.
Fee Increase Lapping — The Math
The September 2024 fee increase ($5 Gold Star/Business, $10 Executive) is still contributing to YoY growth because memberships renew on a rolling annual basis.
| Quarter | Total Fee Growth | Organic (ex fee/FX) | Fee Increase Contribution |
|---|---|---|---|
| Q3 FY2025 | +10.4% | ≈5.8% | ≈4.6% (first partial quarter) |
| Q4 FY2025 | +14.0% | ≈7% | ≈7% ("less than half") |
| Q1 FY2026 | +14.0% | 7.3% | ≈6.7% ("little less than half") |
| Q2 FY2026 | +13.6% | 7.5% | ≈6.1% |
| Q3 FY2026E | ≈11.5% | ≈7.5% | ≈4% (diminishing) |
| Q4 FY2026E | ≈9.5% | ≈7.5% | ≈2% |
| Q1 FY2027E | ≈8% | ≈8% | ≈0% (fully lapped) |
This creates a "deceleration" headline in Q3 and Q4, but the dollar impact is immaterial: delta between 13.6% and 11.5% on $1.24B base = $26M revenue, ≈$0.04/share after tax. At 48x, that's $2 of stock price. Noise.
The CFO pre-disclosed the 7.5% organic figure on the Q2 call. Every analyst covering COST knows the lapping schedule. Probability of a "dumb money sells the headline" reaction: 15-20%. Even then, 2-3% stock move on 2.37% weight = 5-7 bps basket impact. Not actionable.
Tariff Exposure
CEO Vachris (transcript, Mar 5, 2026):
- "Future impact of tariffs remains extremely fluid as recently eliminated IEEPA tariffs replaced with new global tariffs for at least next 150 days"
- Mitigation: (1) country switching, (2) consolidated global buying, (3) Kirkland Signature lean-in (≈30% of sales, max supply chain control), (4) domestic sourcing
- "We believe our expertise in buying and our limited SKU count model puts us in a position to manage this as well as anyone"
- Already lowering prices where tariffs reduced (textiles, bedding, cookware)
- ≈70% revenue from domestic categories (food, pharmacy, gas)
- IEEPA refund process "not yet clear"
Cross-ticker: Value retailers confirmed tariff beneficiaries (TJX CEO: tariff confusion "indirectly good" for off-price/value).
Low single-digit inflation in nonfoods (≈30% of sales) already flowing through. Margin absorbed. CFO: "we look at it as being up by 5 basis points in the quarter and being able to achieve that growth when we were also lowering prices for members and managing the impact of tariffs."
What the Market Is Pricing
Earnings Trajectory
| Metric | Value |
|---|---|
| Forward P/E (NTM) | 43.85x |
| Implied NTM EPS | ≈$22.43 |
| FY2025 EPS | $18.21 |
| FY2026 H1 (actual) | $9.08 ($4.50 + $4.58) |
| Q3 FY2026 est | $4.95 |
| Implied sustainable EPS growth | 12-13% |
The market is pricing continuation of COST's 10-year EPS CAGR (≈13%), built from: comp sales 6-7% (management-guided), unit growth ≈3% (28-30 new warehouses on ≈930 base), modest operating leverage (≈1-2%), no buyback contribution. This is not heroic — it's exactly what COST has delivered.
PEG ratio: 44x / 12% = 3.7x. S&P 500 PEG: ≈2.1x. COST premium: 1.76x market PEG. Historical COST PEG range (5Y): 2.5x to 4.5x. Current = mid-range.
Sell-Side Consensus
| Source | Target | Implied Return |
|---|---|---|
| Median (37 analysts) | $1,100 | +12% |
| JP Morgan (OW) | $1,060 | +8% |
| BMO (OP, outlier bull) | $1,315 | +34% |
| DA Davidson (Neutral) | $1,000 | +2% |
| Truist (Hold) | $977 | -1% |
23 Buy/Strong Buy, 12 Hold, 2 Sell. 62% bullish, 5% bearish. The debate is exclusively about valuation, not fundamentals. The bears (Truist, DA Davidson) say "fairly valued here." The bulls roll forward 12% EPS growth at the current premium multiple. Sell-side isn't calling for multiple expansion — this is a "hold for the compounder" thesis.
Beat cadence: 4/4 quarters, average +2.1%. Reliable but not blowout — no surprise catalyst.
Options Market — More Cautious Than Sell-Side
May 15 (47 DTE, pre-earnings):
- P/C OI: 1.27. P/C Volume: 3.33. Bearish positioning and flow
- Max pain: $950 (3.4% below current)
- Unusual: $855 puts saw 900 contracts vs 22 OI (40.9x ratio). -13% strike protection
- Put skew: +19.3% OTM vs ATM — steep, paying up for downside
July 17 (110 DTE, spans full 15-week window + May 28 earnings):
- P/C OI: 1.82. Nearly 2:1 puts to calls
- Max pain: $980 (flat)
- Call IV elevated +4.3% above puts (unusual — short sellers hedging upside)
- IV: 28.6% vs 19.9% realized = 8.7% vol risk premium
Implied distribution through July 17:
- Expected 1-sigma move: +/-15.7%. Range: ≈$829 to ≈$1,138
- Earnings day implied move: ≈5.9% (consistent with 3-7% historical)
- Put skew steeper for May than July — market hedging a pre-earnings event (March comps Apr 8 or tariff escalation), not the earnings themselves
Key divergence: Sell-side says +12%. Options max pain says flat. The money is positioned for flat to down, with tail hedges in place for -13%. Options are more relevant for our 15-week window.
Short interest 1.4% of float, 3.4 days to cover. Nobody is actually short.
Mispricing Assessment: None
Stress-tested five potential mispricings. None survive.
1. Fee lapping deceleration. Dollar impact: $0.04/share. Price impact at 48x: $2. CFO pre-disclosed 7.5% organic. Every analyst heard it. Not mispriced.
2. Renewal rate structural decline. Trajectory decelerating (-40 bps to -10 bps/Q). CFO explicitly guided it. Online member mix stabilizing. Not hidden, not accelerating.
3. Valuation premium. PEG 3.7x is mid-range of 5-year history (2.5x-4.5x). No catalyst for compression in window absent a fundamental miss.
4. Tariff second-order effects. Consensus correctly identifies COST as relative winner. CEO's actions match words (cutting prices on reduced-tariff items). Cross-ticker confirms.
5. Options put-heavy positioning. Institutional hedging on a $437B defensive name during trade war = standard portfolio insurance, not directional conviction. $4.4M in $855 put premium vs $2B+ daily traded value.
Counterparty test: If we short COST in the basket, the counterparty is every informed participant — 37 analysts, 92% institutional ownership, monthly comp data, quarterly guided. Information asymmetry = zero. Edge = zero.
Bear Case Audit
| Risk | Severity | Probability | Basket Impact |
|---|---|---|---|
| Beta mismatch (QQQ rally, COST drags) | Medium | ≈55% (QQQ direction) | -17 bps at 2.37% weight |
| Fee lapping headline selloff | Low | 15-20% | 5-7 bps |
| Tariff escalation on nonfoods | Low | 20-30% | Margins absorb |
| Comp deceleration below 5% adj | Low | 15% | Feb was +7%, trend stable |
| Valuation compression | Low | 15% | Requires fundamental miss |
| Renewal rate decline accelerates | Very Low | 5% | 10 bps/Q, slowing |
No bear thesis survives scrutiny. Every risk is either low-probability, already priced, or a portfolio-level beta concern (not idiosyncratic).
Filtration Analysis
At 2.37% weight with beta QQQ = 0.28:
| QQQ Scenario | COST Expected | Filtration alpha if Removed |
|---|---|---|
| QQQ +10% | COST +2.8% | +17 bps (drag removed) |
| QQQ flat | COST +0.3% | -1 bp |
| QQQ -10% | COST -2.2% | -18 bps (cushion removed) |
Removing COST = directional bet on QQQ rally with zero IC. The counterparty is the index methodology.
Why Not Remove
-
No idiosyncratic weakness. 9% sales growth, 7% adj comps, 14% EPS growth, 92% renewal, $17.4B cash, improving inventory turnover, management proactively managing tariffs.
-
Beta mismatch is not removal. 13 of 42 survivors have QQQ beta below 0.5 totaling 11.0% of selectable weight. Removing all low-beta names is a market-timing bet with zero IC.
-
US margin flat is investment, not deterioration. Absorbing wage investments and extended hours, offset by productivity.
-
SG&A one-time. 6 bps from liability reserve charge. Underlying +2 bps.
-
Membership decel is minor. 4.8% vs ≈5% historical. Not structural.
-
Consensus is correct. No information asymmetry. No crowd to fade. No mispricing to exploit.
Calendar

Detail audit — checked every number against 10-Q (2026-03-11) and live market data.
Income statement, segments, tax rates, balance sheet: flawless. All match primary source exactly. H1 FCF $4.9B verified (OCF $7,684M - capex $2,815M = $4,869M). Gross margin waterfall confirmed.
Errors found:
Inventory days ≈24 vs ≈25 uses wrong denominator. Revenue-based gives ≈24d. COGS-based (correct) = ≈27d. Direction right (improving), level off by ≈3 days.
Fee Increase Contribution column bundles FX. 10-Q says fee increase = 35% of Q2 growth (4.76 ppt). Post shows 6.1% — the extra 1.34 ppt is FX, not fee increase. Mislabeled.
Renewal rate sequence "-40 → -30 → -10 bps" — the -30 doesn't map to a quarter. Transcript data: ~-35 bps/Q average (Q2→Q4 FY2025), then -10 bps/Q (Q1-Q2 FY2026). Deceleration is real. The -30 is interpolated.
Digital comp 22.6% vs 10-Q's 23%. Minor but cite the primary source number.
Missing context (more material):
"Digitally-enabled comparable sales" is a NEW metric this year (10-Q line 978). Broader than old e-commerce comp — includes digitally-initiated warehouse fulfillment + Costco Travel. +23% is on a new base, not directly comparable to prior periods. Disclose this when citing it.
Renewal rate is a 7-18 month lagging indicator (10-Q line 1053). Q2 FY2026 rate reflects member behavior from Aug 2024–Jul 2025. CFO's retention programs working NOW won't show in published rate until Q4 FY2026 at earliest. The "decline slowing" narrative is correct but the mechanism is delayed — the post should explain why.
Asymmetric one-time treatment. SG&A liability reserve +6 bps (cost) highlighted. Gross margin non-recurring legal settlement +5 bps (benefit, 10-Q line 1225) omitted. Both immaterial individually. But showing one and hiding the other is selective.
H2 capex acceleration. 10-Q guides $6.5B FY2026 total. H1 = $2.8B, so H2 = ≈$3.7B (+31%). The $4.9B H1 FCF won't repeat.
Nearest options expiry (Apr 17) P/C OI = 0.79 (bullish). Post only shows bearish May/July. Window justifies the focus, but near-term bullish signal adds context — short-term money disagrees with the mid-term hedging narrative.
Verdict: KEEP is correct. None of these change the conclusion. Income statement work is A+. Fee lapping quantification is excellent. Counterparty test is honest. But membership narrative has imprecisions and the options framing is one-sided. Overall grade: B.
