AI Value Investing Portfolio Reaches 66.6% Cumulative Return in Investment Report

Asia Strengthens, US Cools — The Weight of Exchange Rates and Interest Rates

On the morning of the 24th, the KOSPI broke through the 7,000 level, rising to the 7,080 range with a gain of over 1%. Meanwhile, across the Atlantic, the temperature was markedly different. The S&P 500 and Nasdaq closed down about 0.8% each, and the Dow Jones tumbled more than 500 points. Behind this was the won/dollar exchange rate surging to the 1,370 range and the U.S. 10-year Treasury yield breaking past 5.1%. Still, the Philadelphia Semiconductor Index held the line with a 0.8% gain, and this tailwind has flowed directly into the Korean market and the semiconductor-focused 'AI Value Investing Portfolio.' The portfolio's cumulative return has already reached 66.6%, with the initial $10,000 in capital growing to $16,657.

A 15% Gain in 5 Days — The Power of Momentum

The asset growth is impressive. Total assets, which stood at $14,415 on the 17th, surged roughly 15% to $16,657 in just five trading days. Notably, the nearly 6% single-day gain on the 21st reflects how the concentration of most holdings in the semiconductor and AI value chain proved to be a strength amid a storm-like trending market. That said, with the cash balance at zero, the current environment — where the volatility index (VIX) jumped more than 7% in a single day — is a time when a defensive rationale becomes necessary.

Holdings Diagnosis: Prices Compelling Relative to Growth

Stock	Quantity	Purchase Price	Current Price	P/E
NVIDIA	26.6 shares	$184.21	$228.87	28.9
Micron	0.42 shares	$987.48	$1,096.16	23.6
Broadcom	5.67 shares	$326.03	$364.54	46.6
AMD	7.17 shares	$198.62	$623.77	156.3
SOXL	14.65 shares	$71.22	$151.95	50.6
Intel	2.80 shares	$104.56	$123.86	-
Amazon	1.95 shares	$208.39	$254.98	20.8
Meta	0.55 shares	$653.56	$736.60	27.9
TQQQ	1.19 shares	$76.34	$80.83	-

Let's look at the core holdings. NVIDIA, at a P/E of around 29, remains priced within a reasonable range relative to its growth rate. Micron trades at a P/E of 23 with a PEG — a valuation metric relative to growth — of just 0.15, supporting the judgment that the benefits of the HBM memory supercycle are not yet fully reflected in the stock price. Broadcom, too, with a PEG of 0.36, carries little burden when its growth pace is taken into account. AMD, on the other hand, shows a high P/E of 156, but its growth rate, which brings the PEG down to 0.63, provides support — making EPS expansion the key variable. Intel is still posting losses, but the position is largely a bet on expected benefits from the restructuring of the AI supply chain. It should not be forgotten that the presence of leveraged products like SOXL serves as an accelerator in rising markets, but represents the greatest risk when the trend turns downward.

Trade Review: Trimming Leverage for Individual Stocks

2026-08-21	Sell	Micron	0.03 shares	$974.33
2026-08-21	Sell	SOXL	0.85 shares	$122.21
2026-08-14	Buy	Intel	2.80 shares	$104.56
2026-08-14	Sell	SOXL	0.90 shares	$145.36
2026-08-07	Sell	SOXL	0.95 shares	$132.33

The pattern in the trading history reveals a clear strategy. Since early August, the portfolio has realized profits by gradually reducing its position in SOXL, a 3x leveraged product, over five transactions, redirecting those funds into individual stocks such as NVIDIA, Intel, and Micron. The approach is 'stocks over indexes' — reducing leverage exposure while seeking undervalued segments within the same sector. In particular, the additional purchase of Micron on the 18th reads as a classic value-momentum buy, driven by the convergence of an extremely low forward P/E in the 6x range and a PEG of 0.14, combined with confirmation of a trend reversal.

Outlook: Between a Semiconductor Tailwind and a Headwind of Rising Rates

Short-term momentum favors semiconductors. However, U.S. Treasury yields above 5%, the won/dollar rate in the 1,370 range, and rising oil prices and volatility are variables that could break this momentum at any moment. Gold prices falling nearly 1% in a single day also hint at cracks in the preference for safe-haven assets. Rather than resting on strong returns, the portfolio's future hinges on whether growth continues to outpace stock prices. It is time to move quickly to take profits, starting with the stocks whose EPS trajectory begins to bend.
