Is The Business As Weak As The Stock?
On the fundamentals, revenue grew 9.4% over the last twelve months, against a median of 17.9% for S&P 500 Information Technology stocks; its operating margin is 25.0%, versus a median of 21.6%; and the stock trades at 25.3 times trailing earnings against a median of 30.5. The selling is hard to square with the fundamentals: margins above the median and a multiple below the median.

Weakness In One Name Should Be Noise, Not News
For a diversified holder, a streak like this is a data point. For a concentrated one, it is a hole in the plan. The difference is never the stock; it is the portfolio built around it.
Building that portfolio is what the Trefis High Quality (HQ) Portfolio does: roughly 30 businesses with the cash generation and balance-sheet strength to absorb a bad month, selected and rebalanced by rules. It has a track record of outpacing a benchmark that combines the S&P 500, the S&P MidCap 400, and the Russell 2000. Make the next streak, in either direction, someone else’s drama.
