The technical picture

The stock traded 8.4% above its 20-day moving average and 8.2% above its 50-day moving average, and it sat 6.7% above its 200-day moving average. The 50-day average remained below the 200-day average, a sign of a weak longer-term trend, though the stock had been above the 200-day average for 11 consecutive trading days. Relative Strength Index (14 days) stood at 66, a neutral reading, and the stock was 6.7% below the 52-week high.

Fundamentals and valuation

For the four quarters through June 30, 2026, revenue was $10.94 billion, which grew 6.7% from a year earlier.
