Westell Technologies, Inc. (WSTL): fair value, margin of safety and Wheel Score
Technology · Communication Equipment · United States · High Growth
Is WSTL undervalued?
WSTL has a margin of safety of 84%: the stock closed at 6.06 on 16 Oct 2026 against a GLS average fair value of 37.54. 8 of the 8 valuation models that produced a number sit above the price. Our screens treat a discount this large as a strong starting point for a cash-secured put, not as a verdict - the fair value is a model output, and a wide gap can mean the models are missing something the market knows.
The 8 models disagree widely: Lynch gives 6.36 while GLS Growth gives 97.42. A spread that wide means the average is sensitive to which methods you trust; the model table below shows where each one lands, and the Quote page lets you switch any of them off.
The nightly engine files WSTL under High Growth: revenue and earnings growing fast enough that the growth-based models carry the valuation.

Quality and financial health
On financial health WSTL scores 7/9 (Piotroski): most of the nine tests - positive earnings and cash flow, falling debt, rising margins and turnover - are passed, which is the kind of balance sheet a wheel trader is happy to be assigned. The GLS Moat score is 6.2 out of 10: a ten-year record that is consistent in some of the metrics the score tracks (revenue, earnings, margins, cash flow, returns on capital) and patchy in others.
Returns on capital are high - ROIC 28.1%, ROE 29.2%, ROA 24.7% - with debt at 0.04 times equity and a free-cash-flow yield of 33.8%.
Westell Technologies, Inc. pays no dividend, so the DDM model does not apply and a covered-call holder earns only the premium and any price gain. Revenue comes mainly from Product 82%, Service 18%, License and Service 0% (quarter Q4 FY2021).
Institutional ownership scores 5/10, insider activity 5/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 7 / 9 | ROIC | 28.1% |
|---|---|---|---|
| GLS Moat | 6.2 / 10 | ROE | 29.2% |
| Debt / equity | 0.04 | ROA | 24.7% |
| Free-cash-flow yield | 33.8% | Payout ratio | 0% |
| Institutions | 5 / 10 | Insiders · Congress | 5 · 5 / 10 |
Wheel Score 39: No options
WSTL has no listed options in the nightly snapshot, so there is nothing to sell and the stock cannot be wheeled however good the business; the Wheel Score is capped at 39 and shown as "No options" (39 here). The valuation and quality numbers still apply to owning the shares outright.
Volume runs at 1k shares a day on a market cap of $62M, with a beta of 0.41 - a low beta, so day-to-day moves are smaller than the market's; the Stability part of the Wheel Score gives that 6 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 25 / 25 | 84% margin of safety | |
| Health | 16 / 20 | Piotroski 7/9 | |
| Moat | 9 / 15 | moat 6.2/10 | |
