November 16 Investment Report: AI Value Investing Portfolio +31%

A 31% Annual Return Even Amid a Semiconductor Plunge

As the Philadelphia Semiconductor Index plummeted 3.4% in a single day, shaking AI tech stocks across the board, the KOSPI also fell nearly 1%. Over two days in which risk appetite visibly cooled—with Nasdaq 100 futures slipping 1.2% overnight—the AI Value Investing Portfolio has held total assets at $13,099, maintaining a 30.99% return on initial capital. It is proof that the strategy's backbone remains unshaken even in a correction.

The Secret Behind $1,200 in Gains in Just 5 Days

The asset trajectory tells a clear story. Starting at $11,857 on the 9th, assets jumped to $13,007 within two days, reaching $13,099 on the 13th. That is a gain of roughly $1,240, or about 10%, in five days. Notably, assets surged precisely during a period when the semiconductor sector was wobbling—the result of contrarian trading that treats downturns as opportunities.

Holding Diagnostics: Undervalued Memory, Overvaluation Warnings

The portfolio's core remains semiconductors. Micron's earnings per share reach $74, yet its price-to-earnings ratio sits at just around 10x. Its price-to-earnings-to-growth ratio is 0.16, meaning the stock trades at less than half its growth-adjusted value. As long as the memory supercycle logic tied to HBM demand holds, it can be judged as undervalued. Nvidia, too, sits in a reasonable value range with a P/E of 21x and PEG of 0.21. By contrast, AMD, boasting a P/E approaching 125x, has accumulated fatigue from its steep rally, while Intel remains unproven in its recovery with negative EPS. Stocks sitting in growth-adjusted territory that is hard to justify—such as Amazon at 1.24 and Intel at 1.36, though not high-growth names like Apple—require position management.

Trade Review: The Twin Pair of Profit-Taking and Staggered Buying

Recent trades form matched pairs of selling and buying. On the 13th, when news of Nvidia CEO Jensen Huang's resignation wiped out 240 trillion won in market cap in a single day, the portfolio reduced risk by selling a portion of its holdings while keeping core stakes. At the same time, it bought more Micron, reallocating capital into undervalued memory with a forward P/E of 3.8x and PEG of 0.16. When AMD's single-stock weighting reached 27% after a 195% surge, profits were realized through staggered selling across three rounds. What stands out is that the principle of selling high and buying low is operating in combination with position management, not merely mechanical indicators.

Market Outlook: An Expanding Volatility Phase—No Time to Rest on Laurels

With the US 10-year Treasury yield surpassing 5.15%, valuation pressure on tech stocks is mounting, and the VIX volatility index rose more than 3% to 19.3. Layer on the Philadelphia Semiconductor Index's 3.4% plunge, and short-term volatility is likely to grow further. That said, the won-dollar exchange rate is holding steady in the 1,336 won range while oil prices and gold move sideways—signs that this is a realignment within the sector rather than a macro shock. Semiconductor valuations remain attractive even in the correction, but with leveraged products SOXL and TQQQ sitting on unrealized losses, volatility management remains the task ahead. This is not a moment for fear, but for cool-headed, staged buying.
