Bottom line

COST Technical Analysis Summary

COST displays a mixed to bearish technical picture across both daily and weekly timeframes. The stock trades below all key daily moving averages (SMA20, SMA50, SMA200) and below the 20-week and 50-week averages, though the long-term weekly SMA200 at 768.17 retains an upward slope. RSI14 near 40 on both timeframes indicates bearish momentum without reaching oversold territory below 30. The MACD histogram is negative on both daily and weekly, confirming sustained downside pressure. Key support rests at the 20/60-day low of 907.21; a break below that opens the path to the 52-week low at 841.69. Resistance starts at the SMA20 of 949.77, followed by the SMA50 of 984.02. A close above the daily SMA200 at 954.96 would suggest a short-term recovery attempt. The above-average weekly volume during the decline warrants caution.

Daily (July 13, 2026)

Trend
Bearish. Price at 926.43 is below SMA20 (949.77), SMA50 (984.02), and SMA200 (954.96). The SMA20 is below SMA50, confirming a bearish short-term alignment. Price below the SMA200 suggests the stock is in a corrective phase relative to its long-term average.
Momentum
Bearish. RSI14 at 40.28 is below the 50 midline, indicating bearish momentum. MACD at -15.33 with signal at -14.12 and a negative histogram of -1.21 confirms bearish momentum, though the relatively flat histogram suggests the pace of decline may be stabilizing.
Volatility
Moderate. ATR14 at 20.70 (2.23% of price) suggests average daily movement of about 2.2%. Bollinger Bands (910.52 to 989.02) are moderately wide with price below the middle band, reflecting bearish positioning.
Volume
Slightly below average. Latest volume of 2,370,400 is 87.4% of the 20-period average (2,712,330), indicating slightly reduced participation.

Assessment

The daily chart shows a bearish structure with price below all key moving averages. RSI below 40 confirms bearish momentum, and the negative MACD histogram reinforces the downside bias. The stock is positioned at 33.3% of its 52-week range, closer to the low than the high. Key support at 907.21 (20-day and 60-day low) is the critical level to watch. A bounce from this level with above-average volume could signal a short-term reversal. Below 907.21, the next major support is the 52-week low at 841.69.

Weekly (July 6, 2026 week)

Trend
Mixed. Price at 916.25 is below SMA20 (988.25) and SMA50 (954.86) but above SMA200 (768.17). The SMA200 is sloping upward, confirming the long-term uptrend remains intact. However, the short-to-medium term is bearish with price below the 20-week and 50-week averages.
Momentum
Bearish. RSI14 at 40.06 is below the 50 midline. MACD at -3.48 with signal at 7.56 and a deeply negative histogram of -11.04 indicates accelerating bearish momentum on the weekly scale. The signal line is still positive, but the MACD line has crossed below, which is a bearish crossover.
Volatility
Moderate. ATR14 at 46.83 (5.11% of price) reflects normal weekly ranges for a large-cap retail stock.
Volume
Above average. Weekly volume of 12,560,700 is 121.9% of the 20-week average (10,301,825), indicating increased participation during the decline, which reinforces the bearish signal.

Assessment

The weekly chart shows a more nuanced picture. While the long-term trend remains bullish with the SMA200 sloping upward, the medium-term structure has deteriorated. Price below both SMA20 and SMA50 with a bearish MACD crossover and a deeply negative histogram suggests that the stock is in a meaningful corrective phase. The above-average volume on the decline is a cautionary signal. The 52-week position at 29.3% reflects a stock trading near the lower end of its range. The key level to watch is 907.21 (20-week low); a weekly close below this level would confirm further downside toward the 60-week low at 841.69.
