Methodology
The verdict on this page is mechanical: we compute the 14-day Relative Strength Index with Wilder’s smoothing from MRK’s daily closing prices, and apply the conventional thresholds — above 70 is overbought, below 30 is oversold. Moving averages, the 52-week range, and volume comparisons come from the same price history.
Indicators are recomputed after every market close. The AI commentary adds context from current news via grounded search, but never changes the computed verdict. Note: closes are as-traded; a stock split would distort readings for a few weeks until the window rolls past it.
