Ideas
Trim Samsung and SK Hynix until October.
Foreign and institutional investors sold Samsung Electronics and SK Hynix heavily in August while retail buying was driven by a surge in credit balance, with about 40% of new credit concentrated in those two stocks. Because fresh deposits are not coming in and institutions are likely to keep pressing retail positions until the October earnings release, the top two semiconductor names should stay sluggish into September-October. Existing investors should keep a core position around 30% but trim overweight positions into rebounds rather than add.
Rotate into non-semiconductor leadership sectors.
With Samsung Electronics and SK Hynix losing near-term leadership, institutional supply is rotating into other domestic leadership candidates. The speaker is looking for opportunities over the next one to two months in sectors being selected by institutions, including secondary batteries, pharma/bio, robotics, nuclear/power equipment, stablecoin-related names, cosmetics, and semiconductor equipment/materials, especially AI-infrastructure-related groups.
Focus on L&F, Samsung SDI, LGES.
Within secondary batteries the speaker says investors do not need to own many names and stock selection matters; among large caps the focus should be on L&F, Samsung SDI, LG Energy Solution, and on KOSDAQ large-cap EcoPro. At least one secondary-battery name should remain in the portfolio.
Focus on L&F, Samsung SDI, LGES.
The speaker's preferred faster ways to play the secondary-battery and ESS trend are Samsung SDI and L&F, because Samsung SDI is seeing the fastest ESS-driven earnings acceleration and L&F is its biggest beneficiary and the only company able to supply US ESS LFP cathode material. LG Energy Solution and SK Innovation should eventually catch up, with Samsung SDI first, LG Energy Solution second, and SK Innovation third in speed.
Buy LG Chem and LG Energy Solution.
Goldman Sachs published buy ratings on LG Chem and LG Energy Solution, arguing the US executive order restricting large grid-connected foreign battery and power equipment explicitly excludes behind-the-meter distributed storage, so the rule shifts demand toward BTM storage and benefits LG's battery businesses. LG Energy Solution's ESS product mix and utilization are recovering, the stock's bottom looks solid, and the risk/reward is skewed to the upside.
Buy Hyosung Heavy Industries over peers.
Goldman Sachs initiated coverage on Korea's three representative transformer and power-equipment makers, and the top pick is Hyosung Heavy Industries with a buy rating and a target price of 416,000 won, about 50% upside. Transmission-heavy Hyosung is seen as less exposed to later orbital data-center distribution demand uncertainty, while aged US grid infrastructure, AI data-center power demand, low renewable utilization, Korean makers' 95% delivery compliance versus 60% for competitors, and US local production premiums support the group. Hyosung has transformer-focused revenue, expected 34% EPS growth, and US revenue share rising from 35% to 64% by 2030.
Korean ESS chain gains from China ban.
The US is effectively excluding Chinese grid-scale battery and ESS equipment, and since Korea only has about 20% North American share versus China's 80%, Korean manufacturers stand to capture replacement demand. ESS demand is already about 75% of EV battery demand and is expected to overtake EV batteries next year, improving Korean battery makers' bargaining power, North American utilization, and profitability across the ESS value chain.
