SK Hynix trading at significantly lower valuation multiple than Broadcom despite higher operating margin

SK Hynix is trading at a significantly lower valuation multiple than Broadcom, despite the South Korean memory chip manufacturer achieving a higher operating margin. According to The Motley Fool, SK Hynix trades at a fraction of the valuation of Broadcom and Applied Materials. SK Hynix's operating margin stands at around 68 percent, while Broadcom comes in at approximately 49 percent – a difference of 19 percentage points in favour of the memory specialist.

Margin strength with considerable volatility

SK Hynix's profitability has improved drastically in a short time. Net margin rose from 29.9 percent in 2024 to 44.2 percent in the current year, an increase of 14.3 percentage points. Analysts view this as evidence of the high profit potential of the memory market when demand for advanced components exceeds supply.

The flip side: Broadcom's margins are significantly more stable than SK Hynix's, according to The Globe and Mail. The operating margin of the South Korean company fluctuated extremely between 2023 and 2026 – from minus 24 percent to the current 68 percent. This span of 92 percentage points demonstrates the massive volatility the business model is subject to.

Cyclicality remains despite supercycle

The memory chip sector is regarded as the most cyclical segment across all major stock markets – A-shares, US exchanges and Korean indices included. The industry rules are brutal, according to an analysis from August 2026: during upswings, profits explode, in downturns the entire sector suffers losses, market exits and insolvencies. Over the past three decades, this pattern has repeatedly established itself.

SK Hynix operates in this cyclical memory industry, where results depend heavily on global supply and demand. The company competes with Samsung and Micron while simultaneously having to bear massive capital investments. Analysts point out that SK Hynix is heavily dependent on demand for memory and storage – the profitability that ultimately supports the stock price depends on how effectively the company can convert this demand into consistent returns rather than merely cyclical fluctuations.

Although a memory supercycle has developed, cyclicality has not been eliminated. Samsung Electronics reported an operating profit of approximately 81.3 billion US dollars for the third quarter of 2026 – yet pricing and margin stability remain dependent on supply and demand dynamics.

AI demand and product differentiation

An analysis of SK Hynix should distinguish between different business segments: DRAM and NAND, with particular focus on high-value products such as HBM (High Bandwidth Memory), server DRAM and enterprise SSDs. Demand from AI infrastructure is changing conventional memory prices, process transitions and customer purchasing cycles – all factors that affect profits.

AlphaGBM reported in September 2026 that a differentiated view of HBM growth, cyclical valuation and shareholder returns was required. Yahoo Finance noted in early October that the stock could be trading below its fair value if expectations for AI memory are considered – a hint at possible upside potential through specialised, margin-rich products.

Investment thesis with structural risk

SK Hynix offers a valuation discount while simultaneously displaying higher current profit margins, particularly in high-value memory products. However, this advantage is counteracted by proven extreme margin volatility and fundamental dependence on cyclical market dynamics. Broadcom's lower margins are offset by significantly higher stability.

For investors, the question arises whether the cheaper multiple and higher margin compensate for cyclical risk – or whether the structural volatility of the memory market justifies a permanent valuation discount. FactSet consensus estimates for the third quarter of 2026 assign SK Hynix an operating profit of approximately 57.81 billion US dollars, underscoring the current strength of the cycle. Historical experience shows, however, that such high phases are not long-lasting.
