Ship engines pivot to data-center power.
HD Hyundai Heavy Industries rose 5.6% on plans to convert ship engines into data-center-type power-generation equipment, creating a new AI/data-center power capex angle rather than pure shipbuilding demand. The chart shows an uptrend and a double bottom after a July drop, with potential upside toward the 200-day moving average. The speaker suggests heavy-industry exposure may fit better than pure shipbuilding because the specific momentum is engines and data-center power.

Won strength favors utilities, transport, chemicals.
If the won strengthens, Korean utilities and transport are the clearest beneficiaries, based on cited FX betas of about -0.5, with chemicals (-0.34) and steel (-0.31) also advantaged. Airlines benefit from lower fuel, aircraft lease, maintenance, and foreign-currency debt burdens. Representative names cited are KEPCO, Korean Air, Lotte Fine Chemical, and POSCO Holdings.
