26% revenue growth meets 12 quarters of insider selling - when fast growers lose insider confidence.
Applying this lens, a fast grower with exceptional fundamentals trades at a PEG of 1.09 while insiders head for the exits.
Can I explain why this company grows, and is the price fair for the growth I'm getting?
This framework sees a textbook fast grower - revenue exceeding the 20% threshold with accelerating investment in product development. The single-segment focus and geographic expansion support continued growth momentum.
If you can't explain to an eleven-year-old in two minutes why you own a stock, you shouldn't own it.
The growth story is crystal clear: "They protect companies by eliminating network security boundaries." The Zero Trust model represents a fundamental shift in cybersecurity, and Zscaler owns the category with pricing power that tracks inflation perfectly.
The P/E ratio of any company that's fairly priced will equal its growth rate.
With negative earnings, traditional PEG doesn't apply, but using EV/Sales as a proxy suggests fair pricing at 1.09x growth rate. The framework would note strong cash generation offsetting the lack of GAAP profits, though sustainability remains the key question.
Insiders might sell for any number of reasons, but they buy for only one: they think the price will rise.
This framework's asymmetric view gives heavy weight to the absence of buying - not a single insider purchase in 12 quarters despite record cash generation. When those running the business won't buy shares at any price, that's a clear signal.
Can the company survive trouble?
The framework sees a fortress balance sheet - substantial cash, minimal debt, and strong cash generation provide enormous flexibility. This company could survive years of trouble, giving management time to execute the growth story.
Applying this framework reveals a fast grower with an exceptionally clear story - Zero Trust security with pricing power and fortress balance sheet. The PEG equivalent of 1.09 suggests fair value, but persistent insider selling for 12 quarters raises the key question this framework always asks. If management won't buy their own shares after selling $31.6 million worth, why should you?
