Summary

The video discusses the diverging prospects of major Korean battery makers, highlighting Samsung SDI's valuation catch-up and long-term order visibility compared to LG Energy Solution's low factory utilization. It also explores the critical role of Energy Storage Systems (ESS) and optical DSPs in addressing AI data center power and data bottlenecks, with a deep dive into Marvell Technology. Finally, the hosts explain how to interpret large rights offerings, using Samsung Biologics as a case study for buying the dip on growth-driven capex.

  • LG Energy Solution faces low factory utilization due to the EV market downturn.
  • Samsung SDI is experiencing multiple expansion driven by long-term orders and its entry into Tesla's supply chain.
  • LNF is benefiting from its LFP battery mass production and dual-supply to major cell makers.
  • Energy Storage Systems (ESS) are seeing massive growth as immediate solutions for AI power demands.
  • Marvell Technology is highlighted for its dominance in optical DSPs and expanding custom ASIC market share.
  • Rights offerings for facility investments, like Samsung Biologics', can present strong buying opportunities.
Ideas
Moon Ji-ho Executive 2:16
Secured long-term orders and Tesla entry upside.
Samsung SDI is shedding its historical undervaluation as it secures orders through 2028 and aggressively invests after liquidating its display stakes. As a new battery supplier to Tesla, it has room for multiple expansion compared to incumbents, and its forward multiple is expected to drop to the 20x range, driving upward price pressure.
Moon Ji-ho Executive 5:39
Supplying LFP batteries to major cell makers.
LNF is mass-producing LFP batteries for the first time and has started supplying both LG Energy Solution and Samsung SDI, which justifies a multiple expansion as its importance in the ESS market grows.
Moon Ji-ho Executive 5:54
AI power demands drive massive market growth.
Energy Storage Systems (ESS) are being re-evaluated not just as general storage but as a core component supporting AI power control. With global ESS market growth nearing 45-50% and AI capex driving demand, the growth trend is highly resilient.
Park Se-ik CEO, ex-Chief Strategist 6:30
SMR stocks will surge in 2-3 years.
Small Modular Reactors (SMR) are being developed to solve power bottlenecks, but they take about three years to deploy. While ESS is the immediate solution, SMR stocks are expected to surge in two to three years when installations and power generation begin in earnest.
Moon Ji-ho Executive 9:27
Dominates optical DSPs and expands custom ASICs.
Marvell is expanding its custom ASIC market share beyond Amazon to include Google, aiming for over 20% market share. More importantly, it dominates the DSP market for optical transceivers, a critical component for noise reduction in AI data centers, and is advancing in silicon photonics, making it an essential partner for big tech companies.
Park Se-ik CEO, ex-Chief Strategist 15:20
Rights offering dip presents strong buying opportunity.
While rights offerings usually dilute shareholder value, Samsung Biologics' 3 trillion won offering is for facility investment in a growing industry. Since Samsung Group holds over 74% of the shares, they will likely absorb the offering. The short-term price drop presents a buying opportunity for a company with strong future earnings potential.
