SanDisk (SNDK): Assessing Valuation After Recent Momentum and Rapid Gains

Reviewed by Kshitija Bhandaru
Sandisk (SNDK) stock has caught the attention of investors, with shares moving this week. There is a mix of forces at play here, including recent trading action and shifts in market sentiment, making it worth a closer look.
See our latest analysis for Sandisk.
Sandisk's 1-day share price return dropped 5.4%. However, this follows a remarkable 47.8% gain over the past month and an even more impressive 207.8% return over the last 90 days. Momentum has been building, as recent price moves indicate renewed investor optimism about the business and its prospects.

With such rapid gains and a swing in sentiment, investors may be wondering whether Sandisk’s current price reflects an undervalued opportunity, or if the market has already factored in all future growth potential.
Price-to-Sales Ratio of 2.5x: Is it Justified?
Sandisk is trading at a price-to-sales (P/S) ratio of 2.5x, which signals that the market is valuing each dollar of the company’s revenue lower than many of its peers. With a last close price of $127.29 and recent momentum, this metric points to a potential valuation gap.
The price-to-sales ratio is a critical tool when assessing companies that are currently unprofitable, such as Sandisk. It helps investors see how much the market is willing to pay for each dollar of sales. This is especially relevant in sectors where profitability can be cyclical or delayed. Given that Sandisk is still unprofitable but growing revenue, this ratio provides a clearer lens on current market sentiment than profit-based multiples.
Compared to its US tech industry peers, which trade at an average P/S of 2.6x, Sandisk appears attractively priced. Its ratio is also just below the estimated fair value multiple of 2.7x. These competitive benchmarks suggest the market has yet to fully price in Sandisk’s growth profile.

Another View: Discounted Cash Flow Says Undervalued Too
The SWS DCF model offers a different lens on valuation. Compared to the current share price, the model sees Sandisk trading at a 22.7% discount to its fair value. While both approaches highlight undervaluation, an important question is whether the DCF provides an extra margin of safety or introduces different risks to consider.
