Amid an Uneasy Market, AI Value Investing Portfolio Holds 62.43% Return in Investment Report

An Uneasy Market, But the Season for Semiconductors Continues

The Seoul market took a breather on the 29th. The KOSPI closed down 0.27% at 6,870.81, and U.S. markets also edged lower, with both the Nasdaq and S&P 500 slipping slightly. The KOSDAQ, however, bucked the trend and rose, showing that demand for individual stocks remains alive, while the Philadelphia Semiconductor Index gained 1.35%, demonstrating the sector's strength even as the broader market fell. Amid this, the AI value investing portfolio maintained a return of 62.43% on its initial capital, with total assets at $16,243—firmly defending its $16,000-level performance curve even in a wavering market.

From $10,000 to $16,000: Corrections Are a Pause in Growth

Looking at the asset flow over the past five days, the portfolio hit $16,657 on the 23rd, hovered around $16,300 through the 28th, and then slipped slightly to $16,243 on the day. The decline itself amounts to a technical correction following days of cumulative gains. What stands out is the cause of the drop—it came not from the index or from valuation pressure on holdings, but from rising interest rates. With the U.S. 10-year Treasury yield surging to 5.28%, discount rates for growth stocks across the board have risen. Gold futures falling 3.32% in a single day also reflects a reshuffling of safe-haven alternatives in a high-rate environment. That the portfolio defended the $16,000 mark despite these macro headwinds is proof that its semiconductor-focused stock selection has not lost its way.

Holdings Check: The Center of Gravity for Undervaluation Remains Semiconductors

Micron	0.42	$987.48	$1,053.98	23.8

NVIDIA is the largest pillar of this portfolio. Looking at the figure of a $228 stock price against earnings of about $8 per share, it may seem somewhat high, but with a PEG of just 0.47 when adjusted for growth, the stock is still assessed as undervalued relative to its growth. Micron, with a PEG of 0.16, carries the most attractive valuation in the portfolio. With the HBM-centered memory supercycle lifting earnings estimates faster than the stock price has risen, it is in a classic phase of undervaluation being resolved. Broadcom, too, at a PEG of 0.35, faces little valuation burden relative to growth. AMD, by contrast, has delivered nearly a threefold gain on the purchase price, but its PEG has now climbed to 0.64, changing its character from 'a common stock bought cheap' to 'a momentum stock that has become a burden'—meaning it is time to manage profits. Intel's turnaround to profitability is not yet confirmed, but the investment thesis remains valid on expectations of benefiting from a restructuring of the AI supply chain.

2026-08-07	Sell	SOXL	0.95	$132.33

The strategy evident in the trading history is clear. SOXL, a 3x leveraged product, has been steadily trimmed across multiple rounds to remove daily volatility risk, with the proceeds redeployed into undervalued individual stocks such as Micron and Broadcom. This is textbook risk management—betting on the sector's direction while reducing the damage if that call proves wrong. It is a pity that SOXL has since risen to $142 compared with the $114 sell price on the 18th, but Micron, which was brought in instead, has surpassed $1,050—meaning the portfolio can be judged to have successfully rotated within the sector with no loss in returns. The Intel purchase, likewise, is proactive positioning based on expectations of an earnings turnaround rather than valuation trading.

Outlook: High Rates Are on Trial—Semiconductor Earnings Hold the Answer

The immediate variable is interest rates. With the 10-year yield hovering above 5%, upside for growth-stock valuations is limited. As the 8% one-day plunge in Brent crude suggests, inflationary pressure is showing signs of easing, and the rising rate trend may be nearing its peak. More broadly, with the VIX lingering in the 16s, this is not a panic phase, and the semiconductor index's counter-market strength indicates earnings momentum remains intact. The portfolio's fate ultimately hinges on whether fourth-quarter semiconductor earnings validate the current valuation logic. The judgment remains valid that maintaining the principle of chasing gaps in undervaluation among stocks is the best defense—especially during correction phases.
