Samsung Electronics and SK Hynix stock valuations fell to historical lows as LS Securities analyst Hwang San-hae cautioned that low price-to-earnings ratios may not signal buying opportunities. The analyst stated in a report that Samsung's 12-month forward P/E ratio reached 4.8x while SK Hynix hit 5.3x amid simultaneous stock declines and earnings forecast upgrades. Hwang argued these metrics during the AI-driven memory supercycle's rapid profit reassessment period represent insufficient grounds for increasing portfolio allocations, as low P/E ratios during structural growth phases often reflect market verification of earnings sustainability rather than undervaluation.
LS Securities Analyst Identifies Historical Low P/E Ratios
Hwang San-hae stated in the report that recent stock price declines for Samsung Electronics and SK Hynix combined with upward earnings revisions resulted in 12-month forward P/E ratios of 4.8x and 5.3x respectively, representing historical low levels. The analyst noted that while valuation appeal appears evident, these metrics provide inadequate justification for additional portfolio weighting when considering the discount structure characteristic of AI cycle leaders and valuation errors occurring during periods of rapid earnings reassessment.
Memory Suppliers Face Dual Supply and Profitability Pressures
The analyst assessed that big tech companies currently positioned as AI cycle leaders, including Alphabet and Meta, face dual challenges of continuously expanding capital expenditures to remain in the cycle while reducing technology unit prices to secure profitability. Semiconductor companies benefiting from this dynamic must expand memory supply experiencing bottlenecks before the overall AI cycle slows, according to Hwang's analysis. The analyst explained this scenario forces memory semiconductors to return to being a cyclical industry heavily influenced by investment and supply dynamics.
Samsung and SK Hynix Profits Reach 57% of Hyperscaler Capex
Hwang stated that excessive profit expansion by AI intermediate goods companies could destabilize hyperscalers' investment continuity. The analyst noted that intensifying return on investment pressure relative to hyperscalers' AI investments could undermine justification for additional investment execution. Hwang emphasized that Samsung Electronics and SK Hynix operating profits surged to 57% of hyperscaler capital expenditures, exceeding levels seen during past Nvidia bottlenecks.
Memory Bottlenecks Constrain Device Upgrades
Memory bottleneck phenomena restricting device upgrades represent another risk factor, according to the analyst. Hwang stated that memory baseline requirements for practical AI utilization show steady upward trends, but simultaneous memory bottleneck occurrences pressure device markets. The analyst identified this as a factor fundamentally delaying AI adoption.
Historical Valuation Traps in Tech Sector Cited
The analyst explained that low P/E ratios during structural growth periods or cycle peaks with rising earnings forecasts do not signal undervaluation. Hwang described these as periods when markets verify earnings level sustainability and pre-reflect supply expansion and future margin erosion. The analyst cited cases of Alphabet and Meta from 2020 to 2022, Amazon from 2017 to 2018, and Nvidia from 2023 to 2024 as evidence, concluding the current memory sector occupies an identical valuation trap zone.

Why does the analyst consider low P/E ratios insufficient for investment decisions?
Hwang stated that low P/E ratios during rapid earnings upgrade periods reflect market verification of earnings sustainability and pre-reflect supply expansion and future margin erosion, rather than signaling undervaluation. The analyst cited this as characteristic of valuation trap zones during structural growth phases.
