What The Numbers Say About The Rally
On the fundamentals, revenue grew 3.4% over the last twelve months, against a median of 7.8% for S&P 500 Industrials stocks; its operating margin is 11.8%, versus a median of 17.6%; and the stock trades at 12.5 times trailing earnings against a median of 26.3. The read is mixed: a multiple below the median on one side, revenue growth below the median and margins below the median on the other.

Streaks End. Discipline Compounds
A run like this is genuinely useful information: something about this business has the market’s full attention. But streaks are where discipline gets tested, because the urge to chase strength is strongest right before it pauses.
The Trefis High Quality (HQ) Portfolio channels that urge into a system: roughly 30 businesses selected for consistent cash generation, strong margins, and resilient balance sheets, sized and rebalanced with rules rather than excitement. It has a track record of outpacing a benchmark that combines the S&P 500, the S&P MidCap 400, and the Russell 2000. Enjoy the streak; own the process.
