Summary

The video features Lee Ji-hwan analyzing the recent volatility in Korean semiconductor stocks and the broader market. He explains the mechanical nature of foreign long-short fund flows, which caused the KOSDAQ to bounce while semiconductors dropped, and advises investors on how to position themselves in memory chips, consumer discretionary, and biotech based on macro variables like oil prices and Treasury yields.

  • SK Square's investment merit has weakened as its role as a semiconductor holding company fades.
  • Investors should hold both Samsung Electronics and SK Hynix equally to hedge against shifting HBM market shares.
  • Memory semiconductor makers currently boast higher profit margins than AI hardware designers like Nvidia.
  • Samsung Electronics' recent drop is due to mechanical selling, and its massive shareholder return plan will eventually attract long-term foreign capital.
  • The recent KOSDAQ rally is driven by mechanical short-covering rather than a structural uptrend.
  • Falling oil prices provide a favorable macro setup for holding consumer discretionary stocks like cosmetics.
  • Biotech and pharma stocks should be approached as short-term trades capitalizing on temporary dips in Treasury yields.
Ideas

Switch from leveraged ETFs to underlying stocks.
Investors should use the next strong market bounce to sell semiconductor leveraged ETFs and switch to the underlying common stocks, as leveraged products suffer from volatility drag and daily rebalancing costs that erode value over time.

SK Square's holding company purpose has faded.
SK Square was originally established to vertically integrate semiconductor equipment companies under SK Hynix. However, as SK Group is currently selling off these equipment subsidiaries, SK Square's purpose as an intermediate holding company has become ambiguous, making it less attractive as an independent investment.

Hold both Samsung and Hynix equally.
Investors should hold both Samsung Electronics and SK Hynix in equal proportions. As the HBM4 cycle approaches with Nvidia's new architecture, market share dynamics between the two could shift. Holding both mitigates volatility and prevents damage from these shifting supply ratios.

Hold both Samsung and Hynix equally.
Despite poor communication regarding its shareholder return policy causing a short-term sell-off, Samsung Electronics' actual cash return scale is massive and highly attractive. The current foreign selling is mechanical, and once it ends, long-term foreign funds will flow in, driving the stock to peak around Q4.

Memory makers boast higher margins than Nvidia.
The focus of AI momentum is shifting from hardware designers to memory semiconductors. Memory makers like SK Hynix, Samsung, and Micron are currently generating higher gross margins (70-80%+) compared to Nvidia (low 60%s) and TSMC (mid 50%s), making them the most profitable segment in the AI value chain right now.

KOSDAQ's rise is just mechanical short covering.
The recent rise in the KOSDAQ while semiconductors fell is merely a mechanical short-covering by foreign funds unwinding their long-short positions. It is not a structural uptrend, and foreign funds structurally struggle to buy KOSDAQ stocks due to mandate restrictions, so investors should not expect a massive sustained rally.

Falling oil prices boost consumer discretionary stocks.
As the US opts for long-term economic sanctions on Iran rather than military action, oil prices are dropping. This eases inflation fears and provides a favorable macro setup for consumer discretionary stocks, such as cosmetics, making them a good sector to hold for a longer duration.
Lee Ji-hwan CEO, Aurora Investment Advisory 44:06
Trade biotech strictly as short-term plays.
If US Treasury yields drop temporarily due to the Treasury's use of the TGA account, rate-cut sensitive sectors like biotech and pharma will benefit. However, this is only a short-term window before potential rate hikes or normalization, so they should be traded strictly as short-term hit-and-run plays.
