Bottom line

COST Technical Analysis Summary

COST technical analysis displays a mixed picture with a tentative short-term recovery against a cautious medium-term backdrop. On the daily chart, price at 954.08 has reclaimed the SMA20 (938.38), and the MACD line has crossed above its signal with a positive histogram at 4.56, while RSI14 at 52.54 has recovered above the 50 midline. However, price still trades below the closely grouped SMA50 (956.12) and SMA200 (954.98), which form a resistance zone near 955 to 956. The weekly chart remains bearish with price below the 20-week and 50-week averages and a negative MACD histogram at -7.67, though the upward-sloping weekly SMA200 at 774.20 keeps the long-term uptrend intact. Key support rests at the 20-day and 60-day low of 905.77, and a break below that opens the path to the 52-week low at 840.35. Resistance starts at the 955 to 956 daily average zone, followed by the weekly SMA20 at 977.59 and the 20-day high at 987.55.

Daily (August 3, 2026)

Trend
Mixed. Price at 954.08 is above SMA20 (938.38) but below SMA50 (956.12) and SMA200 (954.98). The 20-day average has turned up and price has reclaimed it, while the closely grouped SMA50 and SMA200 near 955 to 956 form an overhead resistance zone. The SMA200 is roughly flat, reflecting a consolidating long-term structure.
Momentum
Neutral to improving. RSI14 at 52.54 sits just above the 50 midline. MACD at 0.75 is above its signal at -3.81 with a positive histogram at 4.56, showing the MACD line has crossed above the signal after a downtrend, a short-term bullish shift.
Volatility
Moderate. ATR14 at 19.88 (2.08% of price) suggests average daily movement of about 2.1%. Bollinger Bands (903.73 to 973.02) are moderately wide with price near the middle band, reflecting a stabilization after the pullback.
Volume
Slightly below average. Latest volume of 2,012,600 is 91.4% of the 20-period average (2,201,540), indicating moderate participation during the early recovery attempt.

Assessment

The daily chart shows a tentative short-term recovery after the selloff from the May high. Price has reclaimed the 20-day average, the MACD line has crossed back above its signal with a positive histogram, and RSI has recovered to just above 50. However, price still sits below the SMA50 and SMA200, which are closely grouped near 955 to 956, so the recovery is not confirmed until that zone is cleared. The 20-day and 60-day low at 905.77 is the key support to watch.

Weekly (July 27, 2026 week)

Trend
Mixed. Price at 951.89 is below SMA20 (977.59) and SMA50 (952.10) but well above SMA200 (774.20). The long-term SMA200 is sloping upward, keeping the multi-year uptrend intact, while the short to medium term remains bearish with price below the 20-week and 50-week averages.
Momentum
Bearish. RSI14 at 47.68 is below the 50 midline. MACD at -7.03 is below its signal at 0.64 with a negative histogram at -7.67, indicating sustained downside momentum on the weekly scale, although the histogram has narrowed from earlier readings.
Volatility
Moderate. ATR14 at 46.50 (4.88% of price) reflects normal weekly ranges for a large-cap retail stock.
Volume
Slightly above average. Weekly volume of 10,860,400 is 104.5% of the 20-week average (10,389,530), indicating modestly elevated participation.

Assessment

The weekly chart remains cautious. Price holds above the rising SMA200 at 774.20, preserving the long-term uptrend, but trades below the 20-week and 50-week averages with a negative MACD histogram. The weekly gain of 1.80% at the cutoff suggests some stabilization, but momentum has not yet turned positive. The 20-week low at 905.77 is the immediate downside reference; a weekly close below it would open the path toward the 60-week low at 840.35. Resistance at the 20-week average of 977.59 must be reclaimed to confirm a trend shift.
