Ideas
Safer biotech through CDMO business model
He only invests in Samsung Biologics among biotech stocks because it is a CDMO, avoiding the binary outcome risk of drug development. Small biotechs face low success rates, Eroom's law making approvals increasingly difficult, and even phase 3 successes are often already priced in. Samsung Biologics provides safer biotech exposure.
Active biotech ETF for bio rallies
Biotech stocks move together driven by sentiment and interest rates; picking individual names is very risky. When the biotech sentiment tailwind blows, buying a Korean active biotech ETF managed by specialists increases the probability of success while diversifying the high failure risk.
Avoid covered call, buy plain index
Covered call ETFs cap upside when the market rebounds and still suffer losses in a decline, so they are not safe. Now that the market has potentially bottomed, it is better to own the straight KOSPI200 ETF to capture full upside; covered calls are only suitable in a clear sideways range.
Tourism boom lifts department store earnings
Foreign tourist arrivals in Korea are surging, driven by Hallyu and Chinese demand, producing record sales for major department stores. This structural trend is expected to persist for at least five years, leading to sustained earnings growth for Shinsegae, Lotte Shopping, and Hyundai Department Store.
Buy KOSPI 6000, sell 8000 range
Foreign selling is as extreme as during the 2008 crisis but overdone; without a recession, KOSPI should rebound. Historically, strong sell-offs are followed by bounces within 1-3 months. A range-bound strategy of buying KOSPI near 6000-6500 and selling near 8000-8200 is appropriate until October, after which a more sustained rally may develop.
Memory semis cheap, supply shortage persists
Samsung Electronics and SK hynix trade at very low forward PEs of 6x and 4x; the sharp sell-off has already priced in negative news. Memory supply shortage persists, supported by data center demand, and unlike past cycles, long-term fixed supply contracts will dampen earnings volatility. The correction resembles healthy pullbacks that preceded new highs.
Avoid leveraged products for long-term success
Leverage encourages short-term trading and prevents benefiting from long-term uptrends. It magnifies losses, and negative compounding erodes capital. Holding Samsung Electronics long-term was rewarded, but leverage destroys that outcome.
Stick to passive index funds long-term
The vast majority of individual stocks underperform the market; switching to passive index funds now for crash protection is not effective as a timing move, but for the long term, allocating to market-cap weighted index funds like KOSPI200 and S&P 500 beats stock picking and provides necessary diversification.
