Synopsys Holds Valuation Edge Over Cadence on Forward P/E and Cash Flow

A comparative analysis of electronic design automation (EDA) giants Synopsys (NASDAQ: SNPS) and Cadence Design Systems (NASDAQ: CDNS) indicates that Synopsys currently offers a more attractive valuation on key forward-looking metrics, despite both stocks trading at elevated levels. According to data from Investing.com as of October 2, 2026, Synopsys appears cheaper based on expected earnings, cash generation, and proximity to its model-based fair value.

Forward-Looking Metrics Favor Synopsys

When assessing future earnings potential, Synopsys trades at a significant discount to its primary competitor. The company's stock is valued at 32.3 times forward earnings, compared to 43.1 times for Cadence. This suggests the market anticipates a stronger rebound in profitability for Synopsys, whose trailing price-to-earnings (P/E) ratio of 86.3x is likely inflated by temporarily depressed recent earnings, the analysis noted.

In contrast, Cadence appears less expensive on a trailing basis, with a P/E of 69.5x and an Enterprise Value-to-EBITDA multiple of 44.9x, slightly below Synopsys's 48.3x. However, the forward-looking indicators point to a valuation advantage for Synopsys.

Cash Flow and Fair Value Analysis

Synopsys also demonstrates superior cash generation relative to its market capitalization. The company has a free cash flow (FCF) yield of 3.0%, while Cadence's stands at 1.8%. This means investors in Synopsys receive more cash per dollar of market value.

Furthermore, both companies are trading above their model-derived fair values, but the discrepancy is far more pronounced for Cadence. Synopsys's share price is just 2.7% above its calculated fair value, whereas Cadence trades at a 14.0% premium, indicating potentially higher valuation risk for CDNS shareholders. This valuation gap is not explained by performance, as the companies posted similar revenue growth of 15.1% for Synopsys and 14.1% for Cadence in their last fiscal years.

Market Cautions and Pairs Trade Potential

Despite the relative valuation differences, both stocks show signs of being overextended. The Relative Strength Index (RSI) for Synopsys is 73.95 and 70.95 for Cadence; a reading above 70 is typically considered to be in overbought territory. This shared momentum could make both vulnerable in a broader sector sell-off.

The data suggests a potential pairs trade of long SNPS and short CDNS could be considered based on valuation. However, the analysis from Investing.com cautions that critical data for timing such a trade, like the historical price ratio between the two stocks, was not available. Investors should also note Synopsys's negative PEG ratio of -1.57, which reflects distortions in its recent earnings growth.
