KOSPI Enters 7,000 Range Amid Semiconductor Strength, Investment Report Portfolio Tops 65% Return

Semiconductor Tailwinds Lift KOSPI Past 7,000; Portfolio Up +65%

Global markets extended a semiconductor-led rally on the 3rd (local time). The Philadelphia Semiconductor Index surged 2.4% to lead the market, the Nasdaq rose about 1%, and the KOSPI edged up 0.46% around the 7,000 level. Against this backdrop, the AI value investing portfolio posted a return exceeding 65% relative to its initial capital, preserving total assets of $16,527. Notably, dollar-based gains held firm even as the won strengthened, with the USD/KRW exchange rate plunging 1.3%.

Five-Day Trend: Gains Amid Volatility

Over the past five days, the portfolio weathered one bout of turbulence. Starting at $16,519 on the 28th, it slipped modestly for two consecutive days, dipping to $16,243 on the 29th before rebounding for three straight days to reclaim its previous high. The limited losses during the pullback reflect the payoff of a strategy of gradually taking profits on overvalued positions. With the portfolio fully invested and its cash balance near zero, its defensive capacity in downturns ultimately hinges on stock-picking precision.

Meta	0.55	$653.56	$725.93	27.3

The portfolio's twin pillars are stocks that are both cheap and fast-growing. Micron trades at a PEG of just 0.16—a price level relative to growth—suggesting the HBM memory supercycle is not yet fully priced in. NVIDIA, at a PEG of 0.48, also remains reasonably valued given the durability of AI chip demand. AMD, meanwhile, carries a P/E above 150x, but its PEG of 0.62 suggests the valuation is actually reasonable when its growth pace is considered. Amazon, at a PEG of 1.48, looks somewhat rich relative to growth, but its stable 20x valuation serves as a defensive anchor for the portfolio. Intel, despite posting losses, has climbed to $120 on expectations of a restructuring of the AI supply chain.

Trade Review: Cutting Leverage, Rotating Into Individual Stocks

Date	Action	Stock	Shares	Price
2026-09-18	Buy	Micron	0.19	$977.50
2026-09-18	Sell	SOXL	0.77	$114.82

2026-08-14	Sell	SOXL	0.90	$145.36
2026-08-07	Sell	SOXL	0.95	$132.33

The strategy evident in the trading record is clear. The steady trimming of SOXL—a 3x leveraged product—in five installments since August signals an intent to preserve exposure to the semiconductor sector's upward momentum while reducing the share exposed to daily volatility. The freed-up capital was shifted into individual stocks judged to be undervalued, such as Micron and Intel. Swapping leverage for individual names represents a change in the nature of risk: while it remains a bet in the same direction, the positions will increasingly be validated by corporate earnings over time.

Outlook: Between a Liquidity Rebound and Interest Rate Pressure

The day's market indicators showed optimism coexisting with caution. The volatility index plunged 6.6% to settle at 15, and falling oil prices bolstered risk appetite. However, the US 10-year Treasury yield closing higher at 5.28% could weigh on high-multiple growth stocks. That said, the portfolio's core holdings are mostly names without heavy valuation burdens relative to growth, which should offer relative resilience even in a high-rate environment. A short-term correction could come at any time, but as long as the semiconductor earnings cycle holds, the strategy's upward trajectory is expected to remain intact.
