Highlights

Costco's first-quarter 2026 net sales rose 8.2% year-over-year, with both revenue and profit beating analyst estimates.
The company declared a $1.30 per share quarterly dividend payable November 14 and has $1.752 billion remaining under a $4.0 billion share buyback authorization.
Expansion includes a Calgary land purchase and enhanced digital partnerships with Instacart, Uber Eats, and DoorDash, while a lawsuit over U.S. government tariffs may affect future costs.

Earnings beat and expansion offset by ongoing tariff litigation risk

Costco posted strong first-quarter 2026 results, with net sales rising 8.2% year-over-year and both revenue and profit surpassing analyst estimates. The company declared a $1.30 per share quarterly dividend on October 15, to be paid on November 14, and continued its share buyback program under the existing $4.0 billion authorization, with $1.752 billion remaining. Expansion efforts are ongoing, including a new land purchase in Calgary and growing digital partnerships with Instacart, Uber Eats, and DoorDash. Additionally, a lawsuit against the U.S. government over tariffs could impact future cost management.

Bearish momentum prevails as cost struggles below technical barriers

Technically, COST is capped by dynamic resistance at the Ichimoku Kijun line of $886.10, while immediate support is found near the $850 round number. Momentum indicators are negative: MACD and ADX both signal a bearish bias with weak trend strength, while RSI (31.59) and CCI (-133.25) highlight oversold conditions on the daily chart. Stochastic RSI and BBP are also deeply oversold, underscoring strong seller dominance, and the Awesome Oscillator confirms alignment with the prevailing downside trend.

Downside risk dominates as range-bound trade likely without breakout

Over the next week, COST is expected to fluctuate within a volatility band of $841.00 to $859.00. The probability of further declines remains very high (over 80%), while a significant rebound scenario is less probable. Consolidation within this range is the baseline expectation. Should price reclaim and close above $886.10, a bullish reversal may develop, but a break below $850–$841 support could open the way for additional downside.

Viktoras Karapetjanc, analyst at Traders Union, notes that despite strong fundamental results and ongoing expansion, Costco is still weighed down by clear bearish sentiment and technical pressure. He sees persistent downside momentum in the short term, though robust sales growth and shareholder actions are likely to support longer-term optimism. As risk aversion dominates near $850.00, the baseline expectation is consolidation with a positive bias if the stock can reclaim key resistance. "Any recovery above $886.10 could quickly shift market sentiment, and I remain constructive on Costco’s prospects as underlying fundamentals stay strong."

Previously it was reported that Costco is trading below its key moving averages, with persistent downside pressure confirmed by bearish signals from momentum indicators including MACD, ADX, and consecutive oversold readings on RSI and Stoch RSI. Resistance is identified near $886 with dynamic support lacking above, and near-term price action is expected to remain range-bound with a higher risk of further weakness unless key resistance levels are reclaimed.
