Costco's Success and Investment Strategy
- Unconventional Retail Model: Costco's business model focuses on selling a wide range of products at low prices, with an average gross margin of only 11%, yet it generates $1.4 billion in high-margin recurring revenue through its membership model, enhancing customer loyalty and frequent visits.
- Significant Scale Advantage: In the latest fiscal quarter, Costco reported net sales of $68.2 billion, and despite carrying only 4,000 SKUs compared to 30,000 at typical supermarkets, this limited selection gives it strong negotiating power with suppliers, maintaining low prices and high customer traffic.
- Stock Valuation Misalignment: While Costco is known for its low-price strategy, its stock trades at a high P/E ratio of 52.6, indicating that the market values its stability and predictability, even though its diluted EPS has grown by 16.4% over the past five years, suggesting its valuation may not be justified compared to faster-growing tech stocks.
- Outstanding Market Performance: As of March 5, Costco's trailing 10-year total return reached 691%, significantly outperforming the S&P 500 index; however, investors should carefully consider whether its high valuation is reasonable to avoid potential investment risks.

Iran War Pressures Off-Price Retailers Amid Rising Oil Prices
- Oil Price Surge Impact: Since the onset of the U.S.-Iran conflict earlier this month, crude oil prices have surged to levels not seen since 2022, with WTI and Brent crude nearing $120 per barrel, leading to a 70 basis point decline in consumer spending among lower-income shoppers, exacerbating economic pressures.
- Retailer Pressure: According to Wolfe Research, off-price retailers like Dollar General and Walmart, which primarily serve low-income consumers, are expected to face greater pressure as rising oil prices may force these shoppers to tighten their budgets, impacting sales performance.
- Stock Price Declines: Dollar General's shares have fallen 5% over the past week, while Walmart and Advance Auto Parts have seen declines of nearly 3% and 7%, respectively, indicating a market sensitivity to rising energy prices and their impact on consumer confidence.
- Challenges from Import Dependence: Retailers reliant on Chinese imports, particularly in flooring and decor, may face significant headwinds as the Shanghai Containerized Index rises due to logistical issues in Southeast Asian ports, further complicating product shipments to the Middle East.

JPMorgan Turns Bearish on Market Amid U.S.-Iran Tensions
- Market Sentiment Shift: JPMorgan traders have turned tactically bearish as the U.S.-Iran tensions show no signs of easing, indicating a neutral positioning that lacks extreme de-risking, which could lead to increased market volatility in the short term.
- Energy Sector Sell-off: Last week, the energy sector was the most net-sold, as investors took profits ahead of the weekend, anticipating de-escalation; however, crude prices surged, with West Texas Intermediate futures briefly exceeding $110 per barrel, marking the highest levels since Russia's invasion of Ukraine in 2022.
- Future Outlook: JPMorgan traders express optimism towards defense stocks, oil refiners, and grocery companies, while remaining bullish on crude, natural gas, and energy producers, suggesting potential investment opportunities amidst the current crisis.
- Volatility Expectations: Morgan Stanley's chief U.S. equity strategist believes that despite market volatility, stocks are closer to the end of this rolling correction over the next 6-12 months, particularly as the pace of oil and dollar increases will determine the duration of volatility.
