Weekly setup

Mixed setup

The weekly trend is active. Price is 17.6% above the Trend Line and sits at 53.2% of its 52-week range. The latest completed week returned -6.9%, after a -19.7% four-week move. The latest factor snapshot indicates quality ranks weakly versus its universe; growth ranks strongly; valuation is expensive relative to peers. Options positioning is volatility with 56/100 conviction, while the latest news-sentiment score is 55/100. Near-term considerations: volume confirmation is below normal; earnings are due in 4d.
