September 18 Investment Report: AI Value Investing Portfolio +44.1%

Markets Lifted by Semiconductor Tailwinds, Portfolio Cruises Along

Global markets continue to rally, led by semiconductors. The Philadelphia Semiconductor Index surged more than 3% to lead the advance, the Nasdaq jumped 1.69%, and the KOSPI climbed 1.82% to break above the 6,840 mark. The benefits of this momentum flowed straight into the AI Value Investing Portfolio. With cumulative returns now exceeding 44% on an initial capital of $10,000, total assets have grown to $14,414. It is the kind of rising curve that emerges when the market's direction and a strategy's direction align.

A Breather from the Peak, But the Trend Remains Intact

The asset trajectory shows the portfolio hitting $14,779 on the 11th and $14,987 on the 14th, followed by a temporary pullback and a rebound toward the $14,400 range. This reads as a natural breather after the semiconductor rally entered overheated territory in early September. That said, with the Philadelphia Semiconductor Index surging more than 3% on the day and momentum reviving, the correction appears closer to noise within the broader trend. The VIX falling to 15.44, as fear quickly subsided, also adds support from the demand side.

Holdings Check: Valuation Relative to Growth Is the Core of This Rally

Semiconductors remain the backbone of this portfolio. Nvidia trades at a P/E of just 27, and with a PEG ratio of only 0.45, the consensus is that it remains undervalued. Broadcom, too, carries a PEG of 0.34, leaving little price burden relative to growth. Micron boasts the most attractive valuation in the portfolio at a PEG of 0.14, though its high share price of $926 means the position is kept small to control risk. Intel, by contrast, is unprofitable, making traditional metrics difficult to apply; it is best classified as a classic momentum play betting on the recovery of the AI supply chain. The steadily reduced weighting in leveraged products like SOXL reflects a deliberate commitment to volatility management.

Trade Review: Trimming Leverage in Favor of Individual Stocks

Recent trading shows repeated sales of SOXL. Each time the semiconductor index surged, the portfolio realized some profits and reduced its leveraged exposure, reallocating the proceeds into individual names such as Nvidia and Intel. Rather than simply betting on index gains, the strategy has reshaped its risk profile toward selectively holding individual stocks that are undervalued relative to their growth. The partial sale of Meta was a response to sector rotation amid intensifying competition in the advertising market—assessed as a balanced approach that avoided excess.

Outlook: Falling Oil and Stable Rates Offer Relief

The macro backdrop is a tailwind as well. WTI crude has slipped below $101 a barrel, easing inflationary pressure, while the U.S. 10-year Treasury yield has edged down from the 4.9% range, somewhat softening the rate pressure on growth stocks. That said, with the won-dollar exchange rate rising to 1,386, vigilance over foreign capital flows persists. Overvaluation risks in individual names—such as AMD, whose valuation has grown expensive—also warrant attention. Ultimately, the sustainability of this rally hinges on whether semiconductor earnings deliver. The undervaluation suggested by the metrics remains valid, but a disciplined approach that stays alert to overheating will determine the next phase.
