What if you invested monthly in SK Hynix for 15 years?

Why this period and asset
SK Hynix focuses on memory chips such as DRAM and NAND, and grew strongly with the memory cycle after joining SK Group in 2012. This 15-year window starts from 2011 and passes through several memory boom-and-bust cycles, the 2020 COVID crash, and the AI-demand phase. Memory chips are a classic cyclical industry whose prices swing widely with supply-demand imbalances, and the stock has risen and fallen sharply along with that cycle.
Interpreting the result
As a single stock heavily driven by the memory cycle, SK Hynix had periods in this window with far deeper maximum drawdowns and longer loss periods than the index during each downturn. Monthly investing buys at cheaper prices during those downturns, lowering your average cost, but concentrating on one stock and one industry means recovery can take long when the cycle is bad. Looking only at a survivor that grew is survivorship bias, so the severe cyclical risk must always be considered.
Caveats & limits
This result simplifies dividends, trading fees and taxes, and past performance does not guarantee the future. SK Hynix is a Korea-listed won (KRW) stock, so the figures are in Korean won. A single stock can have a deeper maximum drawdown and longer loss period than an index, and looking only at winners is survivorship bias. In particular, memory chips are so cyclical that downturn drawdowns and recovery periods can be very large.

Frequently asked questions
Why does the memory cycle move the stock so much?
Memory chips are a cyclical industry whose prices swing widely with supply-demand imbalances. So in downturns the maximum drawdown can deepen and the recovery period can lengthen.
Is a single stock riskier than an index?
Yes. Concentrating on one stock and one industry can mean a deeper maximum drawdown and longer loss period than an index. An index spreads across many names, reducing single-name risk.
Does monthly investing remove the cyclical risk?
No. Buying cheaper during downturns lowers your average cost, but it does not remove the cycle itself. Always check the maximum drawdown and recovery period together.
