Summary

Park Se-ik reviews the Philadelphia Semiconductor Index and argues it is in a volatile right-shoulder phase similar to 2021-22, with rallies into October earnings to sell and a likely final down leg next year. He stresses that the U.S. 10-year Treasury yield must fall to around 4.4% for a strong bull market to start. His system's Vasily buy signal supports a KODEX Leverage long, while KOSDAQ remains in a bear market and a KOSPI rebound toward a 50% retracement carries early-September caution. The session is a market/timing update rather than a bottom-up stock-picking session.

  • Philadelphia Semiconductor Index rebounded but Bollinger Band upper band remains extended and MACD is negative, so Park expects range/right-shoulder behavior.
  • He plans to reduce semiconductor exposure into October earnings and buy any post-earnings dip before a possible final down leg in 2026.
  • The 10-year Treasury yield at 4.68% is the key barrier; a drop to 4.4% after U.S. midterms would support a strong bull market.
  • The Chesley Vasily signal fired and has historically targeted around 10% gains on KODEX Leverage with recent 25-50% returns.
  • KOSDAQ was downgraded to bear market status in June, and the system still signals escape/avoid.
  • Foreigner spot-futures positioning turned positive, suggesting a grind higher toward a 50% retracement before early-September caution.
  • He recommends seasonal risk management in July-October and not forcing trades.
Ideas

Semis: rally into earnings, then final decline.
He expects the Philadelphia Semiconductor Index to stay in a volatile right-shoulder range rather than breaking out because the Bollinger Band upper band is too extended and the MACD oscillator has turned negative, similar to the early stage of the 2021-22 semiconductor top. He would reduce semiconductor exposure into the strong October earnings from Samsung Electronics and SK Hynix, buy dips again because Q4 earnings should be strong, and then expects one more down leg next year when DRAM spot prices weaken and capacity supply increases, potentially breaking the prior low. The bearish analog is invalidated only if September Micron or Ambarella earnings push the index above its prior high and produce a buy signal near 14,000.

10-year yield must fall for bull market.
He argues the market cannot rally strongly while the 10-year U.S. Treasury yield keeps rising; it just rose to 4.68%, and this yield is the key variable that must fall decisively. If the 10-year yield drops to the 4.4% handle, especially after the U.S. midterm elections, he expects a very strong bull market to begin.

KOSDAQ in bear market; avoid or escape.
Chesley AI cut its KOSDAQ allocation by three stages in June and told subscribers to escape; KOSDAQ has entered a bear market, and the KOSDAQ buy signal that appeared at the top immediately got trapped. He treats KOSDAQ as a bear market rather than a dip-buying opportunity.

Vasily signal triggered; buy KODEX Leverage.
The Chesley system's Vasily buy signal has fired, and when this signal is applied to KODEX Leverage it has historically targeted about a 10% gain with a small maximum drawdown. The most recent signal on July 28-30 produced 25%, 43%, and 50% returns in different cases, and he believes this system will make money from this year into next year.

KOSPI rebound to 50% retracement, September caution.
Foreigners' spot-futures positioning has turned positive again, so he expects the KOSPI rebound to grind higher toward a 50% retracement of the prior decline, but he warns to be cautious again in early September. This gives a short-term rebound setup with a defined seasonal caution point.
