Investment Report for September 29: AI Value Investing Portfolio +65.2%

With the KOSPI Frozen in a Bull Market, the AI Value Investing Portfolio Held Its '+65%'

September 28 was a scorching day for the Seoul market. The KOSPI plunged a full 2.7% in a single day, collapsing to around 6,800. With rising U.S. interest rate pressure compounding oil price jitters, risk-off sentiment hit its peak. Yet amid the turmoil, the AI Value Investing Portfolio examined here maintained a cumulative return of +65.19%, having grown an initial $10,000 into $16,519. Each time the market wobbles, the strategy's steadiness becomes all the more apparent.

Two Straight Days of Asset Growth — the Rally's Core Is Semiconductors

A look at the portfolio's asset movement over the past five days shows it has held up even during the correction phase. After rallying to $16,657 on the 23rd and taking a one-day pause, it rebounded from $16,431 late last week to close modestly higher at $16,519 today. That assets grew even on a day the Korean market suffered a double-digit plunge means the returns are rooted not in any particular market but in the fundamentals of individual stocks — the AI semiconductor cycle itself.

Holdings Check: A Defense Line Called Undervaluation

AVGO	5.67 shares	$326.03	$352.81	45.1

Amazon	1.95 shares	$208.39	$249.67	20.1
Meta	0.55 shares	$653.56	$751.66	28.3
SOXL	14.65 shares	$71.22	$151.45	-
TQQQ	1.19 shares	$76.34	$79.60	-

NVIDIA, the portfolio's cornerstone, trades at a growth-adjusted level (PEG 0.47) still below 1 when its earnings growth rate is factored in — a strong case for accumulation. Micron's earnings have surged on the HBM-memory supercycle, leaving its price substantially cheap relative to actual results. AMD's price-to-earnings ratio looks lofty at 161x on the surface, but with earnings climbing rapidly, dividing by the growth rate makes the valuation far less burdensome. Intel, by contrast, has yet to turn a profit, making it a so-called 'story' stock that leans on expectations of an AI supply chain recovery. The still-heavy allocation to SOXL, a pure leveraged product, remains a double-edged sword in a correction phase.

2026-08-07	Sell	SOXL	0.95 shares	$132.33

The core of the past month's trading is clear: reduce leverage, focus on earnings stocks. The portfolio has steadily trimmed portions of SOXL, a 3x leveraged product, to lock in profits, redeploying the proceeds into individual names with attractive growth-adjusted valuations such as Micron, NVIDIA, and Intel. With the tailwind from index leverage weakening, the strategy has been doubling down on stock-picking. That said, the Intel purchase is a bet on a company whose earnings have yet to materialize, so upcoming earnings reports will be a turning point.

Market Outlook: The Shadow of 5.26% Yields

The indicators are sending signals that warrant caution. The U.S. 10-year yield has surged to 5.26%, pressuring growth stock valuations; the VIX jumped 9%; and even gold fell nearly 4%. Oil is showing a divergent pattern — Brent has plunged while WTI has climbed — deepening macro uncertainty. On the flip side, the won-dollar exchange rate stabilizing at 1,357 eases concerns about foreign capital outflows. In a high-rate environment, even growth stocks can see heightened volatility. Reducing this portfolio's excessive semiconductor leverage remains an ongoing task.
