Costco Has Raised Its Dividend Every Year Since 2004. Here Are 3 Reasons I'd Buy It in September and Never Sell.

Costco reports fiscal Q4 results on Sept. 24, with 16-week net sales expected to rise 11.3% to $93.9B and analysts projecting EPS up 12% to $6.56. The article flags a likely special one-time dividend later this year, suggesting potentially ~$20/share+ based on prior patterns, while noting the stock trades at ~47x trailing earnings and is ~3% down over the past year. Despite the valuation and mixed growth history, the near-term catalyst mix (earnings + special distributions) is framed as a buying opportunity.

Analysis

Costco still screens as a quality compounder, but at this multiple the stock now trades more like a duration asset than a retail business. That means the next leg is less about sales growth and more about whether membership income and disciplined expense control can keep offsetting wage inflation; a clean EPS beat should be required just to sustain the premium, not expand it. If execution merely matches expectations, upside from here is likely modest because the market is already paying for near-perfect consistency.

The special dividend is a liquidity and positioning event, not a moat event. It can attract dividend-oriented flows and force some incremental buying from funds that benchmark cash return, but that support tends to be temporary and often reverses after the record/ex-date window. The more meaningful catalyst over 1-3 months is any signal on renewal rates, traffic elasticity, or a future membership-fee increase; absent that, the cash return may just recycle capital rather than re-rate the business.

Second-order, Costco's scale keeps pressuring branded consumer goods and mid-tier grocers that lack its traffic density and procurement leverage. BJ is the most direct relative-value comparison, but WMT's grocery and membership ecosystem is the bigger structural competitor if consumers keep trading down. Over 6-18 months, the main risk is a subtle slowdown in comp momentum: that would hit a high multiple faster than fundamentals deteriorate, while a true negative would be only a few points of deceleration rather than an outright sales miss.

Key Decisions for Investors

• Do not chase COST outright ahead of earnings; prefer to wait for either a post-print pullback of 3-5% or a clear guide-up before adding. Risk/reward is poor if the quarter is merely in-line because the valuation already discounts durability.
• Relative-value: long COST / short BJ over the next 1-3 months if management confirms stable renewal economics and traffic. The pair expresses quality premium and scale leverage; exit if BJ shows faster membership momentum or COST commentary turns cautious.
• Use options rather than stock if you need event exposure: buy a modest-sized call spread in COST into the print only if implied volatility remains below recent realized vol. The thesis is a small upside pop on another incremental beat, not a rerating.
• After any special dividend announcement, consider fading the post-announcement excitement with short-dated put spreads once the cash-return headline passes. The expected move from the payout itself is transient, while the ex-date can remove a support layer.
• Watch for a renewal-rate or fee-increase update as the real catalyst. If management implies comp growth slipping toward low single digits, reassess immediately; that would likely trigger 10-15% multiple compression even without an earnings miss.
