TECHNICAL RATING
TECHNICAL SCORE
89 / 100
Summary
Price sits 8.6% above the 20-day (230.92), 12.2% above the 50-day (223.38) and 25.7% above the 200-day (199.45), with the 50/200 relationship in a Golden cross. Momentum is confirming that rise: MACD is above its signal (7.033 vs 4.734) and the RSI(14) is 70.6 and still rising, so momentum and trend are aligned. The move comes with a breakout above the upper Bollinger band, but volume is running below its 20-day average, which tempers conviction. Watch whether price can hold above the band on higher volume or if a pullback toward the 20-day MA restores balance.

Rating ruleFormula: the Technical Score is a weighted composite of eight inputs. Trend inputs — price vs. the 20-day (10%), 50-day (15%), and 200-day (25%) moving averages, and the 50/200 Golden or Death cross state (10%) — carry roughly 60% of the weight. Momentum inputs — MACD (12/26/9) vs. its signal line (15%) and RSI (14) state (10%) — carry 25%. Bollinger-band position (5%) and volume vs. the 20-day average (10%) round out the remainder. Each input contributes +1, 0, or -1, weights are re-normalized when a component is unavailable, and the weighted sum is thresholded at +/-0.45 to Bullish, Neutral, or Bearish.
