Positive fundamentals offset by investor caution after dividend increase

Costco reported 12% year-over-year sales growth and a 92% membership renewal rate in its latest quarter. The company also appointed a new chief global supply chain officer and increased its quarterly dividend, marking 22 consecutive years of annual dividend raises including a recent 13% increase. Speculation continues surrounding a potential special dividend in the second half of 2026, though price action has remained under broader selling pressure.

Anton Kharitonov, expert at Traders Union, views Costco's recent decline as a warning sign despite the company’s strong fundamentals. He highlights that persistent downward momentum is reinforced by the price staying below its 20-, 50-, and 200-day moving averages. Kharitonov is wary of the market's disregard for positive news like robust sales growth and a record renewal rate, signaling underlying sentiment remains bearish. He emphasizes that momentum and structure suggest sellers remain in control. "Even with Costco’s impressive dividend history and leadership changes, the technical setup and sentiment imply further downside risk should the $926.7 level fail to hold."

Viktoras Karapetjanc, expert at Traders Union, remains constructive on Costco’s outlook given its stellar 12% sales growth and high membership retention. He sees the company’s consistent dividend increases and supply chain leadership as setting a strong foundation for further expansion. Karapetjanc believes the macro environment supports retail resilience and expects institutional confidence to persist. "I am optimistic that Costco’s bullish structure remains intact — current volatility is a healthy reset, and further growth is anticipated as the market digests these positive drivers."

Parshwa Turakhiya, analyst, notes that short-term sentiment remains cautious with technicals signaling sellers have the upper hand. He sees the price constrained between $926.7 support and $952.29 resistance, creating an opportunity for active traders to watch volatility. Turakhiya points out that indicators are oversold, so a technical bounce cannot be ruled out. "The setup is ripe for nimble trades — I’d watch for whipsaw moves in this tight range as momentum could shift quickly in either direction."

Downward momentum confirmed as technical signals flag seller dominance

Costco is trading below its 20-day, 50-day, and 200-day moving averages at $969.83, $998.19, and $957.93, respectively, indicating downward momentum across all time frames. Short-, medium-, and long-term trends are skewed to the downside, even though the 50-day and 200-day moving averages remain in bullish alignment. The price is currently capped beneath resistance at $941.3 and supported near $926.7. Momentum indicators strengthen the bearish outlook: the MACD and RSI both signal selling pressure, with an RSI at 41.68 and Bear/Bear Power (BBP) at -1.29, reflecting dominance by sellers and an oversold reading. The Awesome Oscillator adds a negative momentum signal, while the ADX is neutral, pointing to weak trend strength. Although the Stochastic RSI suggests the potential for a technical bounce, overall momentum and structure remain bearish.

Earlier, analysts noted that despite strong sales growth and high membership renewal rates, Costco was expected to remain in a period of technical consolidation amid medium-term downside pressure. This view is reinforced by the latest market dynamics, with bearish momentum prevailing and traders advised to monitor for a decisive move below $926.7 as a trigger for additional downside risk.
