Ideas
Medicare rate freeze pressures insurer margins.
The 2027 Medicare Advantage payment increase was set at only 0.09% versus expectations of 4-6%, while medical costs continue to inflate. This compresses margins for government-dependent US health insurers such as UnitedHealth, Humana, CVS Health, Alignment Healthcare, and Molina Healthcare; UnitedHealth also missed guidance and fell sharply.
Amazon closes weak stores, margin focus.
Amazon is closing Amazon Fresh and Amazon Go stores and converting them to Whole Foods, exiting unprofitable grocery formats and focusing on its stronger grocery assets. Combined with continued cost and headcount reduction, this should support margin defense into earnings.
Meta deal drives Corning optical growth.
Meta will pay Corning around $6B through 2030 for optical fiber cable for AI data centers. Fiber is more power-efficient than copper and increasingly critical for GPU connectivity, Corning's optical communications business is growing quickly, and its CEO expects hyperscalers to become its largest customers by 2027.
DRAM shortage persists through 2026-2027.
Micron announced an additional $24B Singapore investment focused on DRAM, but wafer output begins around 2H28, so DRAM shortages are likely to persist through 2026-2027. Micron remains a beneficiary of tight memory supply.
Lam Research leveraged to DRAM capex.
Micron's advanced DRAM line expansion benefits semiconductor equipment makers, and Lam Research has the greatest technology share and earnings leverage in DRAM processes. That is why it rose most among equipment names and hit a new high.
GM buyback and guidance inspire confidence.
GM beat on EPS, raised annual guidance, increased its quarterly dividend by 20%, authorized a $6B buyback, and offset over 40% of tariff costs. This shows confidence and cost control, with analyst targets around $85-100.
Bitcoin box; watch $70k support.
Bitcoin remains range-bound; it bounced after liquidations around the $89,200 gap, but a break below the prior low in the high-$70,000s would confirm a bearish trend. Until then, it is a monitoring setup.
Analog and data center recovery lifts TXN.
Texas Instruments reported in-line revenue and better-than-expected Q1 guidance as industrial semiconductor recovery continues and data center demand grows for a seventh straight quarter. Backlog is rising, and analog/data-center strength can drive EPS upgrades even though consumer/TV remains weak.
AI storage demand tightens HDD market.
Seagate's earnings beat with strong margin expansion because AI's shift from training to inference is driving massive storage demand. High-capacity HDDs are supply-constrained, cloud customers need cost-efficient storage, and Seagate has long-term contracts through 2027 with 2028 demand under discussion.
YouTube data powers Google AI moat.
YouTube captures user attention and generates enormous video data, which strengthens Google's AI (Gemini) and supports ad pricing. This data advantage could make Google a durable market-cap leader.
Dollar weakness supports KOSPI momentum.
The dollar index broke below 96, similar to the 2017-18 period that supported Korean equities. With foreign investors still underweight and Korean stocks having lagged the S&P 500 over 10 years, KOSPI momentum can continue.
Anthropic stake value lifts SK Telecom.
SK Telecom's stake in Anthropic, purchased for about KRW 130B in 2023, is now worth over KRW 1.5T. A potential sale could enable dividend resumption, and the stock remains cheap.
Leeno may benefit from HBM sockets.
Market rumors suggest HBM will begin using test sockets, which could benefit Leeno Industrial. The rumor is not confirmed, so it is a watch item rather than a high-conviction trade.
Thin margins, competition make LG Innotek avoid.
LG Innotek has rallied 160% and has 2026 visibility, but operating margin is only about 3-4% versus roughly 10% historically, indicating intense competition, especially from Chinese camera module makers. It should be avoided unless it proves leadership in a new market like robot cameras.
Prefer Samsung Electro-Mechanics over LG Innotek.
If choosing in the camera module/component space, Samsung Electro-Mechanics is preferable to LG Innotek because of better margin/package solution positioning and potential exposure to robot camera demand.
KOSPI overextended; wait for correction.
KOSPI's 50-day spread is around 117%, an overextended level. Foreign and institutional investors find entry timing difficult after the fast rally, so chasing is unattractive; a correction would be the better buying opportunity.
Korean semis outperform in first quarter.
Foreign investors remain interested in Korea but are struggling with entry timing after the fast rally. Within Korea, semiconductors are expected to outperform in Q1 despite profit-taking, and corrections are viewed as buying opportunities.
Rate-sensitive soft AI themes vulnerable.
Uranium, space, and robotics are second-generation soft AI themes that are highly sensitive to rate and CPI surprises. If inflation disappoints, these high-valuation ETFs/stocks could fall 30-40%, so they are risky to own without a correction.
Yuan and yields favor China insurers.
Chinese insurance stocks are strong because a stronger yuan typically leads investors to buy financials, rising Chinese bond yields improve insurers' investment returns, and Beijing has encouraged insurers to buy more stocks. They still look undervalued.
Solid-state battery equipment leader re-rating play.
Lead Intelligent is the global No.1 battery equipment maker with 15% global and 19% China share, supplying CATL, BYD, Tesla, LG Energy Solution, and Samsung SDI. It has a unique full-line solid-state battery equipment solution; earnings are inflecting, contract liabilities and overseas orders are rising, overseas margins are much higher, and solid-state battery adoption could drive a re-rating.
Samsung dollar breakout leaves foreign upside.
Samsung Electronics broke its prior all-time high in dollar terms in January, and in USD terms it has only recently caught up with its 2021 peak. Foreign investors still have room to buy, especially as KOSPI has lagged the S&P 500 over the past decade.
