Summary

Yeom Seung-hwan of LS Securities reviews the weak late-summer Korean market, arguing that the KOSPI has built firm 6,500 support through corporate buybacks and that investors should not panic-sell. He sees September as all about US rates: the market wants yields capped, not a sharp drop. He favors accumulating Samsung Electronics and SK hynix on intact memory fundamentals, watches Micron's earnings reaction as the next catalyst, and prefers AI data-center growth themes such as secondary batteries/ESS and construction, with banks only as defensive hedges.

  • The KOSPI repeatedly defends 6,500 and is viewed as bottoming, with no need to cut stock exposure.
  • Retail investors remain scarred and trading value is low; a meaningful rally still needs foreign buying.
  • September is all about US rates: the market wants yields not to spike, while a sharp yield drop would signal recession or an AI capex pullback.
  • SK hynix's Solidigm Nasdaq listing is not denied but remains one option and would be negative for shareholders without protection.
  • Micron's late-September earnings reaction is the key catalyst for memory sentiment.
  • Samsung Electronics and SK hynix are accumulation candidates because memory fundamentals and large buybacks remain intact.
  • AI data-center themes favored include secondary batteries/ESS and construction; banks are only a defensive hedge.
Ideas

KOSPI bottom is firm; don't sell.
Yeom sees the KOSPI repeatedly testing the 6,500 level on an intraday basis and closing above it each time. He reads that as a market bottom with strong support, helped by corporate buybacks and other demand that defends the downside. He says investors do not need to cut stock exposure here and should not treat this as a selling zone.

Solidigm IPO remains possible risk.
Yeom reads SK hynix's Solidigm pre-IPO disclosure as not a denial: a Nasdaq listing remains one of several options under review. He notes Solidigm has become a valuable AI data-center enterprise SSD business, so listing without shareholder protection would dilute SK hynix shareholders' upside and likely trigger backlash. His base case is that it probably will not be forced through, and current stock-price impact is limited.

Micron reaction decides memory sentiment.
Micron's late-September earnings, especially the market reaction, are the key trigger for memory sentiment. AI-related earnings in the US have generally been good and Nvidia's latest reaction improved, so if Micron's good results get a positive reaction, warmth can spread to Samsung Electronics and SK hynix. If the reaction is poor, the memory recovery takes longer.

Rates should stay capped, not crash.
Yeom says September is dominated by US interest rates. The market is not hoping for a sharp drop in yields because a sudden collapse would imply either a US recession or big tech retreating from AI investment, which would hurt Korean equities. Instead, the market wants yields capped from rising, roughly in the 4.6% to 5% zone, and Fed speakers are actively signaling to prevent yields from breaking higher.

Buy Samsung and SK hynix dips.
Samsung Electronics and SK hynix have corrected 30-40% from highs even though memory fundamentals have not cracked and AI earnings news has stayed positive. Buyback and cancellation programs are very large and recurring into next year, which supports the stocks. He sees current weakness as an accumulation opportunity for investors who believe earnings will keep growing, even though retail sentiment remains weak.

Battery sector growth returns via ESS.
The secondary-battery sector is becoming a growth story again because ESS demand from data centers is surging. Q3 earnings should inflect, and next year's operating-profit growth rate is expected to rank first across sectors. Chinese battery makers are excluded from the US, and Korean makers are expanding capacity; he suggests buying the sector on pullbacks after its recent run.
Yeom Seung-hwan Director, LS Securities 30:45
Construction benefits from data center buildout.
Construction should be treated as an AI data-center growth sector. Korea is actively encouraging data-center builds, US big tech faces local opposition and could choose Korea, and global hyperscalers are already partnering with Korean firms. With huge build costs per GW and domestic construction companies having real earnings and clearer near-term orders, he sees construction as one of the clearest data-center plays.
Yeom Seung-hwan Director, LS Securities 32:37
Use banks as defensive hedge only.
For portfolio construction, he argues growth must remain core but some defensive exposure is useful. Bank and financial stocks are one such hedge, especially for periods when rates rise. They should only be a supporting allocation, not the main position.
