Is FSLY undervalued?

Fastly, Inc. (FSLY) closed at 21.04 on 5 Nov 2026, 21% above the GLS average fair value of 17.44. Only 1 of the 2 models that produced a number value the shares above the current price. The margin of safety is negative, so the stock fails the "below fair value" Wheel Trade Filter; a premium of this size is common for companies whose growth the models are conservative about.

Only 2 of the nine models produced a value (DCF, 10 Cap); the others need a dividend, positive free cash flow or positive book value the company does not have yet, so the average rests on a narrow base.

The nightly engine files FSLY under Speculative - it is losing money or its Piotroski health score is 3 or lower - which caps its Wheel Score at 45 and keeps it out of the Sunday Scan.

Nine valuation models for FSLY

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. The last two rows are shown for reference and never enter the average. The Quote page lets you switch any model off and add your own margin of safety.

Quality and financial health

Financial health is average - FSLY passes 6 of the nine Piotroski tests, which passes the "Piotroski 6 or more" Wheel Trade Filter. The Financials tab on the Quote page shows which tests fail. The GLS Moat score is low at 3.5 out of 10: returns on capital, margins or the balance sheet have not shown a lasting edge yet - often a young company, a thin-margin business or one that has only recently turned profitable.

Returns on capital are thin or negative - ROIC -8.9%, ROE -13.1%, ROA -8.1% - with debt at 0.46 times equity and a free-cash-flow yield of 1.7%.

Fastly, 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 Network Services 73%, Security 23%, Other 4% (quarter Q2 FY2026).

Institutional ownership scores 10/10, insider activity 1/10 and Congressional trading 5/10 on the GLS smart-money scales.

Wheel Score 23: Weak

FSLY scores 23 out of 100 on the Wheel Score, in the Weak band (under 50): it fails filter 2, a real business, not a gamble - speculative (a loss, or a weak Piotroski score); and filter 3, below fair value - trades 21% above our fair value; and filter 5, can repay its debt - 3.4 years to repay its debt (over 3); and filter 7, a premium worth selling - implied volatility 182% (over 80%), and the parts are thin too - value weak, premium weak, moat fair, health good, red flags fair, option trading strong, stability fair. The score is not a judgement on the company; it says the price, quality and premium do not line up for selling puts on it today.

Implied volatility is 182%, above the 80% ceiling of the Wheel Trade Filter on premium. The premium looks generous, but moves of that size can blow through any strike. The option chain is deep: 61,692 contracts of open interest across all expiries, which means tight fills at most strikes.

Volume runs at 8.4M shares a day on a market cap of $3.4B, with a beta of 0.36 - a low beta, so day-to-day moves are smaller than the market's; the Stability part of the Wheel Score rates that fair.
