Samsung vs. SK Hynix: A Question of Volume Versus Concentration
On why SK Hynix has rallied sharply while Samsung Electronics has lagged, panelists pointed to structural differences between the two. SK Hynix's simple, transparent exposure to AI-driven HBM demand makes it easy for investors to price, much like Micron or Kioxia, while Samsung's diversified portfolio — spanning semiconductors, home appliances, and foundry — dilutes the visibility of its memory upcycle. Recent labor-related noise around a strike was also cited as a temporary drag on Samsung shares.
Still, panelists argued both stocks retain distinct strengths over the longer term. SK Hynix benefits from being seen as foreign investors' top pick amid its pending U.S. ADR listing, while Samsung's appeal lies in sheer earnings volume. With quarterly operating profit expected to rise from roughly 57 trillion won in Q1 to around 90 trillion won in Q2, a company generating 100-200 trillion won in quarterly operating profit commands resources for virtually any reinvestment or acquisition.
Panelists reiterated that investing is a battle of absolute profit, not return rate — institutional investors compete on returns to attract fund inflows, but individual investors should focus on actual gains in won terms. They noted that the average Korean brokerage account holds only around 10 million won in cash, and urged investors not to fixate on relative underperformance within the same sector.
Samsung shares fell more than 1% to around 358,000 won on the day. The combined market cap of Samsung and SK Hynix topped 4,000 trillion won, with SK Hynix alone surpassing 2,000 trillion won. Top foreign net-buy names included SK Hynix, Samsung Electro-Mechanics, LS Electric, Hyosung Heavy Industries, HD Hyundai Heavy Industries, and Samsung C&T.
