Sandisk Corporation (SNDK): fair value, margin of safety and Wheel Score

Is SNDK undervalued?

SNDK has a margin of safety of 35%: the stock closed at 1,403.34 on 16 Oct 2026 against a GLS average fair value of 2,168.82. 5 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: DCF gives 16.29 while GLS Growth gives 4,761.42. 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 SNDK under High Growth: revenue and earnings growing fast enough that the growth-based models carry the valuation.

Each model turns the latest filed numbers into a value per share; the GLS fair value is the simple average of the ones that produce a positive number.

Quality and financial health

On financial health SNDK 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 7.9 out of 10, built from ten years of revenue, earnings, margins, cash flow, share count and returns on capital scored for consistency - a high reading that points to a durable business.

Returns on capital are high - ROIC 70.9%, ROE 72.7%, ROA 50.8% - with debt at 0.02 times equity and a free-cash-flow yield of 5.7%.

Sandisk Corporation 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 Edge 61%, Datacenter 33%, Consumer 6% (quarter Q4 FY2026).

Institutional ownership scores 9/10, insider activity 1/10 and Congressional trading 10/10 on the GLS smart-money scales; the last recorded insider buy was on 17 Sep 2026.

Wheel Score 78: Good

SNDK scores 78 out of 100 on the Wheel Score (Good band, 65-79). The score blends the margin of safety (Value, 25/25), Piotroski health (16/20), the GLS moat (12/15), the option premium on offer (12/20) and how easily the stock trades (14/20). Premium (12/20) is the part holding the score back.

Implied volatility is 92% on the near-the-money contracts 20-60 days out - above the 60% ceiling of the sweet spot. Premiums are large, but the Wheel Score tapers the Premium points (12 of 20) because volatility this high usually comes with a reason. The option chain is deep: 178,551 contracts of open interest across all expiries, which means tight fills at most strikes.

Volume runs at 7.3M shares a day on a market cap of $202.8B, with a beta of 5.22 - a high beta, so the stock tends to move more than the market and a strike can be gapped through; the Stability part of the Wheel Score gives that 14 of 20.

The Wheel Score ranks ~7,400 US stocks for selling cash-secured puts and covered calls; it is updated nightly and is not a recommendation. The walkthrough lesson shows how the score fits into a trade, start to finish.
