Ideas
2 p.m. dips are foreign accumulation.
Retail investors have sold more than 18 trillion won of KOSPI stocks since September 3, and Lee expects additional selling into the Chuseok holiday. He believes this excessive individual selling, while foreigners accumulate, may limit further market downside and creates an opportunity to accumulate leading sectors in tranches during the shakeouts.
HBM4 favors Hynix and Samsung.
SK Hynix ADR surged about 6% while Micron Technology fell, and Lee attributes the divergence to HBM4 order momentum. Nvidia's Vera Rubin production plans are approaching, and SK Hynix is likely receiving significant HBM4 volume. Micron faces redesign questions that could take a year or more to resolve, so year-end HBM4 supply is likely to be won by SK Hynix and Samsung Electronics, widening their performance gap over Micron.

AI infrastructure gains on US stimulus.
US midterm-linked infrastructure stimulus and Korea-US negotiations over eight nuclear reactors are fueling AI infrastructure names. Power equipment, electric wires, optical communications and nuclear-related construction saw strong buying; power equipment has a double momentum from AI datacenter demand plus US infrastructure expansion, and he expects strength into September-October.
Samsung SDI trades on ESS momentum.
Secondary batteries are transitioning from chronic short covering/liquidation pressure to a tradable bottoming setup. Samsung SDI is the strongest name because ESS demand and all-solid-state battery momentum are attracting funds, while materials names are also seeing early buying. EV fundamentals remain weak, so he suggests a trading approach that buys pullbacks rather than chasing.
Maintain semiconductor positions through expiry.
Ahead of the futures-options simultaneous expiry, Lee says investors should not be scared by the possibility of foreign selling. Simultaneous futures-options expiry tends to produce less volatility than options-only expiry because the futures roll had already caused volatility the prior week. With semiconductor names still positioned upward, he advises maintaining semiconductor positions through the expiry.
NAND/DDR4 surge supports memory stocks.
August memory pricing strengthens the semiconductor cycle: NAND prices rose roughly 18-30% and DDR4/legacy memory prices jumped more than 25%. Samsung Electronics and SK Hynix have continued to shift capacity, pushing legacy prices higher, and semiconductor exports/capex are steeply rising, so the memory upcycle remains intact.
NAND surge favors SanDisk over Micron.
August NAND prices jumped sharply and Lee observes SanDisk's stock flow has improved more than Micron's because SanDisk is more directly levered to NAND pricing. This supports favoring SanDisk over Micron on the NAND recovery leg.
Buy weakness for year-end leaders.
Despite September seasonal weakness and negative macro headlines, the market is not falling much on bad news. Lee recommends using the current anxiety to begin building year-end positions in leading groups: Korean semiconductors, power equipment, consumer discretionary and bank stocks. These areas are expected to lead into the year-end rally.
Buy consumer discretionary on oil dip.
Cosmetics and other consumer discretionary names that had been strong are now correcting because of the short-term oil price spike. Lee expects this to be a dip-buying opportunity and sees momentum returning after the Chuseok holiday as oil pressure fades and stimulus-sensitive consumption improves.
US AI strength lasts into year-end.
Lee expects US AI/semiconductor strength to last at least through year-end. Washington is likely to release stimulus/policy support from late September, and infrastructure-related flows are already moving. The Nasdaq is stronger than the Dow, confirming that AI/tech leadership remains intact.
Fiscal stimulus revives US consumer stocks.
After mid-September, Lee expects US policy stimulus to shift toward consumption support, which should revive US consumer discretionary stocks. If tech and consumer discretionary form a two-track leadership, the broader equity market could enter a stronger phase.
