64% Returns on Semiconductor Tailwinds: Autumn for the AI Value Investing Portfolio

As of 1:30 a.m. KST on the 26th, the KOSPI crossed the 7,080 mark, up 0.9%, while the Nasdaq and S&P 500 continued their upward march. Notably, with the Philadelphia Semiconductor Index rising 1.41% and leading market momentum, the AI Value Investing Portfolio—which invests primarily in semiconductors—recorded a +64.31% gain over initial capital, with total assets reaching $16,431, significantly outperforming the market.

While the portfolio's asset curve trends upward, the journey has been far from smooth. Over the past five days, assets grew about 6.4%, from $15,441 to $16,431, but volatility was high—after hitting a peak of $16,657 on the 23rd, the portfolio pulled back within a single day. Nevertheless, each drawdown was endured and new highs were reached, a testament not to index-following but to the power of a strategy grounded in the valuations of individual stocks.

Holdings Diagnosis: A Map of Undervaluation Told by the Numbers

Stock	Shares	Purchase Price	Current Price	PER
Broadcom	5.67	$326.03	$350.36	44.6
AMD	7.17	$198.62	$629.26	160.1
Amazon	1.95	$208.39	$249.38	20.1
TQQQ	1.19	$76.34	$78.58	31.9
Intel	2.80	$104.56	$127.39	-
Meta	0.55	$653.56	$777.59	29.3
NVIDIA	26.59	$184.21	$224.58	28.4
SOXL	14.65	$71.22	$146.33	48.7
Micron	0.42	$987.48	$1,080.53	24.5

The portfolio's twin pillars are NVIDIA and Micron. NVIDIA, with a PEG ratio of 0.48—below 1, suggesting the stock has yet to keep pace with its growth rate—remains the largest holding. Micron, at a PER of 24.5x and a PEG of 0.16, reads as the most extremely undervalued when factoring in the HBM demand boom. AMD, meanwhile, carries a nominal PER above 160x, but its growth-adjusted PEG of 0.63 indicates that high growth offsets valuation pressure. Meta, at a PEG of 0.98, plays a steady workhorse role near fair value, while Intel is a recovery play awaiting a spark from expectations of a return to profitability.

The key themes of the trading record are 'reducing leverage, rotating into individual stocks.' SOXL, a 3x leveraged product, surged on semiconductor strength, roughly doubling in value, but from early August through mid-September, positions were trimmed in four separate rounds to manage daily volatility risk. The freed-up capital flowed into Micron, with a forward PER of 6x and a PEG as low as 0.14, and into Intel, seen as a beneficiary of the recovering AI supply chain. By cooling off the hot fervor of index leverage and replanting into cheaper assets, this judgment has driven the cumulative returns.

Market Outlook: Currency Stability and Falling Oil—Plus Homework to Do

The won-dollar exchange rate fell nearly 13 won to 1,354 on the day, favorable for foreign capital inflows. Brent crude's 6.6% plunge also eases inflationary pressure. However, the U.S. 10-year Treasury yield remains elevated at 5.18%, a variable that could cap the upside for growth stock valuations. With the VIX having fallen to 14.87, the market has already priced in a considerable degree of optimism. This portfolio, too, carries the structural risk of semiconductor concentration, making continued rebalancing toward undervalued stocks—the approach taken so far—the best weapon for navigating the volatile second half of the year.
