• – The EMA stack describes trend, not entry timing.

Cross

• – Nothing was found for the last EMA50/EMA200 cross within the computable window; there is no dated golden cross or death cross reported here.

What would change this read

• – A weekly close back above EMA20 939.32.
• – A weekly close back above EMA50 949.37.
• – A move that invalidates the current weekly stance relative to EMA200 816.46.

MACD vs signal line

• – MACD: -14.87
• – Signal: -11.85
• – MACD is below the signal line, which is a bearish posture.
• – Last signal-line crossover: bearish on 2026-05-25, 19 bars ago.

Histogram

• – Histogram: -3.02
• – The histogram is negative, so weekly momentum is still on the weak side.
• – The 4-bar change is 3.8109, which means momentum is decelerating in bearishness compared with 4 bars ago, but it is still negative.

Zero-line position

• – MACD is below zero.
• – Last zero-line cross: bearish on 2026-07-06, 13 bars ago.
• – This is a separate signal from the signal-line crossover: the signal-line cross was on 2026-05-25, while the zero-line cross was later on 2026-07-06.

Divergence checks

• – Bearish divergence check: none.
• – Bullish divergence check: none.
• – The computed pivot comparisons did not report either bullish or bearish divergence.

What would change this read

• – A weekly MACD move back above the signal line from -14.8656 versus -11.85 would change the signal-line posture.
• – A weekly MACD move back above zero from the current -14.8656 would change the zero-line posture.
• – A bearish divergence would need to be found on a future pivot comparison; the current checks from 2026-08-10 close 961.1/macd -7.1117 -> 2026-09-21 close 922.77/macd -15.359 and 2026-07-06 close 916.25/macd -4.1539 -> 2026-09-14 close 895.31/macd -15.5808 found none.

• – Current RSI and state: Weekly RSI(14) is 43.94, which is neutral. It is neither overbought nor oversold.
• – Direction over the last four weeks: RSI 4 bars ago was 38.92, and the current reading is 43.94, so the weekly RSI has been rising over the last four weeks.
• – Most recent 70/30 band event: The most recent band event was falling back below 70 on 2025-02-17, 85 bars ago.
• – Divergence checks: No bearish divergence was found. The last two price pivots were 2026-08-10 close 961.1 / rsi 49.31 and 2026-09-21 close 922.77 / rsi 44.35. No bullish divergence was found. The last two price pivots were 2026-07-06 close 916.25 / rsi 39.87 and 2026-09-14 close 895.31 / rsi 37.36.

What would change this read

• – A move of weekly RSI back above "70" would change the state from neutral to overbought.
• – A move of weekly RSI to "30" or lower would change the state from neutral to oversold.
• – A new divergence result that is not "none" at the next pivot check would change the divergence section.

• – ATR value and meaning: The weekly ATR(14) is 38.67, which is 4.20% of price. That means the stock’s typical weekly movement is about 38.67 points, relative to a 920.65 close.
• – Volatility vs. eight weeks ago: Volatility is contracting because ATR(14) is down from 44.51 eight bars ago to 38.67 now.
• – Weekly movement bands: The 1x ATR band from the close is 881.98 to 959.32, which marks a normal expected weekly range around the current close. The 2x ATR band is 843.31 to 997.99, which marks a wider expected weekly range. These bands describe expected weekly movement, not a price forecast.

What would change this read

• – A reversal in the comparison to the prior reading, with ATR(14) moving back above 44.51.
• – A further drop in ATR(14) below 38.67, which would extend the contraction already shown from 44.51.
• – A move beyond the current 1x ATR band edges of 881.98 or 959.32, which would indicate a weekly move larger than the current 1x ATR expectation.

52-week high and low

• – 52-week high: 1096.5 set 2026-05-18
• – 52-week low: 844.06 set 2025-12-15

How far price sits from each

• – Latest weekly close: 920.65
• – Distance from the high: -16.04%
• – Distance above the low: 9.07%

What the position within the range says

• – Midpoint of the 52-week range: 970.28
• – Position in the 52-week range: 30.3% where 0% = at the low and 100% = at the high
• – This places COST in the lower part of its weekly 52-week range, below the midpoint, which indicates the stock is not in the upper portion of its longer weekly cycle.

What would change this read

• – A move back above 970.28 would shift COST above the midpoint of the 52-week range.
• – A test of 844.06 would put the stock back at the 52-week low.
• – A push to 1096.5 would return COST to the 52-week high.
