A Stock-Specific Run, Or A Market Move?
The market explains little of this: the S&P 500 gained 1.2% over the same 5 sessions, including dividends, against Zscaler’s +18.9%. Over the past three months the stock is up 64.8%, a window that includes the streak; over the other 58 sessions of that window it was up 38.6%.
What The Numbers Say About The Rally
On the fundamentals, revenue grew 25.4% over the last twelve months, against a median of 17.9% for S&P 500 Information Technology stocks; and its operating margin is -3.6%, versus a median of 21.6%. Zscaler does not have positive trailing earnings, so there is no meaningful price-to-earnings multiple to compare. The read is mixed: revenue growth above the median on one side, an operating loss on the other.
