Price is 18.3% above its 200-day simple average ($124.42) and 17.2% above its 200-day exponential average ($125.66). Volatility is stretched, extension is stretched, and daily moves are only weakly tied to SPY.
Bar: distance from SMA 200. Ring: +17.2% from EMA 200.
The bullish rule requires price strictly above both the 200-day simple and exponential averages. This describes position, not an investment recommendation.
29.3% annualised, one-year average 28.6%. Trend: expanding.
Realized volatility uses 21 daily returns and the equity convention of 252 days. The percentile depends on available history. Low volatility does not mean an investment is safe.
Measured against 756 valid distances. A stretched reading does not establish that price will reverse.
Absolute percentage distance from SMA 200 is divided by the rolling standard deviation of those distances over 756 observations, requiring 378 valid distances. Zero or undefined deviation is unavailable.
Same regime as SPY. With 10-year yields: -0.23. With gold: 0.13.
Pearson correlation ranges from −1 to +1; strength uses its absolute magnitude, while the sign gives direction. 251 paired returns were used; at least 30 are needed. Co-movement can change and does not establish causation.
MRK follows the bullish trend rule, with price 18.3% above its 200-day simple average. Recent volatility is stretched relative to its available history. Absolute extension is 1.1 times the historical deviation of its distance from the average. Return correlation with SPY is 0.06.
The four measurements describe prices. They do not measure business quality or determine fair value. Source reporting dates can differ from the price date.
Reported trailing P/E is 116.9x. Forward P/E is 15.9x, based on estimates. Reported revenue growth is 5.1%. Net profit margin is 4.8%. Free cash flow is positive.
19 of 28 analysts rate it Buy or Strong Buy. The reported mean analyst target is $158.56. Analyst targets are estimates and can change.
Institutions hold 82.9% of shares in the reported data. Reported insider ownership is 0.1%. 10 recent insider transactions are available. Transactions alone do not establish a future price direction.
Completed bullish phases had a median duration of 6 observations. The ongoing phase is excluded. Among matched windows that returned within 1σ of the moving average within 90 observations, the median time was 8 observations.

The bullish trend rule held on 98% of observations over the trailing year. The largest peak-to-trough decline over that year was 11.4%. 22 daily moves exceeded 3% in magnitude.

The observed curve is normal: long-term rates exceed short-term rates. The 10-year yield is 4.95%.
Volume is 86% above its 30-day average; the recent volume trend is stable.
Implied volatility is 99% below realized volatility. This comparison alone does not establish whether an option is cheap or expensive.
Price is 1.1 times the historical standard deviation of its distance from the 200-day average above that average. This measures extension; it does not establish the likelihood of a reversal.
Daily returns show weak correlation with SPY over the latest shared year of observations (r = 0.06). The sign describes movement in the same direction. Correlation does not establish causation or measure portfolio diversification on its own.
Calculated from available price history. Separate measurements can be related to one another; they are not independent confirmations of a trading signal.
