Costco rises 2.30% over the week

Highlights

Shares of Costco climbed 3.57% over the past week to $942.09, trading above short-term moving averages but below the 200-day average.
Technical indicators show mixed signals, with shares at the top of the weekly range and momentum turning overbought, while trend strength remains flat.
For the coming week, shares are expected to consolidate between $916.81 and $956.53, with immediate support at $937.04 and resistance at $962.08.

Omnichannel sales and membership gains sustain upbeat sentiment this week

Costco reported its fiscal 2026 results with total revenue of $303.15 billion and diluted earnings per share of $20.76, according to TradingView. Membership growth and strong omnichannel sales were key contributors to performance, and the U.S. and Canada renewal rate reached 92.3%, as highlighted by Simply Wall St. The fourth quarter saw net income of $2.998 billion on $93.87 billion in sales.

Resistance and overbought signals cap upside as momentum stalls near range top

On the daily chart, the stock is at the very top of its weekly range after a 3.57% stretch upward, yet trend strength is flat, reflecting a contained move within a narrow range. Momentum signals are mixed, with CCI at 154.94 and Stochastic RSI at 100, both in the overbought zone, while the MACD stays neutral. Immediate support is seen at $937.04, with significant resistance at $962.08 from the MA-200. This setup suggests a pause or consolidation phase is likely as buyers and sellers battle around current levels.

Neutral bias persists in coming week with range-bound action expected

For the next five trading days, the expected range is $916.81 to $956.53, with an equal 50% probability of an increase or decrease. The base case is for shares to consolidate inside this band, holding near $942.09 unless momentum breaks. A bullish scenario would require a close above $962.08, targeting further gains. Any reversal below $937.04 support could open a retreat toward the lower bound of the range at $916.81.

Anton Kharitonov, expert at Traders Union, notes that shares of Costco have staged a 2.3% rebound over the past week, trading near $942. Despite this move, he sees buyers turning cautious as daily technical signals suggest exhaustion. The daily indicators, with CCI at 154.94 and Stochastic RSI at 100, highlight an overbought condition, while flat trend strength points to a pause or consolidation near current levels. Fundamentally, Costco's record revenue of $303.15 billion and robust membership renewal rate at 92.3% demonstrate solid company performance, but these strengths have yet to drive a decisive breakout. Kharitonov believes that the next five days will likely see shares stuck between support at $937.04 and resistance at $962.08. "Unless momentum decisively breaks above $962.08, I expect a sideways week with buyers and sellers remaining in balance," he says.

Previously it was reported that limited-time product launches and innovative brand engagement contributed to driving sales growth for leading retailers. Costco's current technical setup now brings consolidation risks to the forefront, with traders advised to monitor the $937.04 support and $962.08 resistance as key pivots for near-term direction.
