With Samsung Electronics and SK hynix entering a consolidation phase until their July earnings, the concentration of funds in mega-cap AI stocks is unwinding, fueling a rotation trade. KOSDAQ small/mid-cap stocks that were previously overlooked due to flow concentration — especially semiconductor equipment/materials, consumer goods with strong exports, K-entertainment, and biotech — are starting to rebound. Stocks with good earnings and export performance that were pushed down are likely to see a re-rating. This rotation could last 2–3 weeks.

The KOSPI market is likely to continue its uptrend in May based on a historical pattern: when April rises more than 5%, May follows 80% of the time. Combined with the IBKR-driven structural inflow of foreign capital, the market remains favorable.

Naver shows a clear volume-driven breakout from its bottom, indicating a trend reversal. The stock had lagged the index but is now catching up with a 30-40% rise from the bottom. Combined with a new AI and data center narrative and solid fundamentals, Naver could become a new market leader.

SK Telecom is recommended because NVIDIA selected it as an AI partner, creating a new narrative. The company's subsidiary Entropic is expected to turn profitable from Q2. This gives SK Telecom a unique AI edge among Korean telcos. The stock broke out to new highs on heavy volume, and investors should hold or add rather than sell.

As leverage regulations are likely to tighten and the market digests the recent leveraged ETF fallout, money will rotate from over-levered large caps into semiconductor equipment and materials stocks (소부장). These names, such as PSK Holdings, TES, VM, and TS, fell less during the correction and rebounded more strongly, showing relative strength. They stand to benefit as large-cap stabilization triggers renewed interest in the semiconductor supply chain.

Hyundai Mobis is an attractive undervalued play within the Hyundai Motor Group, similar to how LG Innotek outperformed LG Electronics. Mobis is pursuing internalization of Boston Dynamics robot components, has cheap valuation, and still has growth potential. The stock has high intraday volatility but a strong upward trend, and the speaker sees it as a candidate for significant upside, possibly exceeding Hyundai Motor's gains.

The group benefits from the broader AI and robotics theme spreading from Hyundai to LG.
