Why this period and asset
Samsung Electronics is Korea's largest company by market cap, spanning semiconductors, smartphones, and appliances. This 20-year window includes several downturns: the 2008 global financial crisis, the 2020 COVID plunge, and the 2022 chip downcycle. Notably, in 2018 Samsung carried out a stock split (sharply lowering the per-share price and increasing the number of shares), improving access for small investors. With a large memory-chip weighting, its earnings and stock were heavily driven by the chip cycle, and even the top company by market cap could not avoid the large swings typical of a single stock.
Interpreting the result
This scenario shows that even the flagship company carries large drawdowns when you concentrate in one stock. Be sure to check the maximum drawdown, underwater period, and recovery time on the results screen. A long 20-year window includes multiple crises and chip downcycles, so it can include deep drawdowns and long underwater periods along the way. Even as the top company by market cap, it is a single stock, so that firm's and industry's risks are fully reflected. Monthly investing spreads out timing but does not remove the concentration risk itself.
Caveats & limits
Samsung Electronics is a KRW-denominated asset listed in Korea, so results are calculated in Korean won (KRW) with no exchange-rate variable. Single-stock concentration means the company's weakness translates directly into losses, and you should be mindful of survivorship bias from examining only companies that have kept their top position. Taxes and trading costs also lower performance. Past performance does not guarantee the future, and this page does not recommend buying any specific stock.

Frequently asked questions
Is the largest company by market cap safe?
Large size does not make a stock always stable. Samsung too suffered large drawdowns during the financial crisis, COVID, and the chip downcycle. The maximum drawdown and underwater period on the results screen show that even a flagship company carries meaningful risk.
Does a stock split affect investment performance?
A stock split lowers the per-share price and increases the number of shares; it does not change the company's value itself. It does improve access for small investors by lowering the per-share price. The calculations here should be understood on a split-adjusted price basis.
With a 20-year plan, isn't a profit guaranteed?
Even over a long period, a profit on a single stock cannot be guaranteed. Results vary with the start and correction timing and the chip cycle, and there can be deep drawdowns and long underwater periods along the way, so you must check the results screen.
