Why this period and asset
Johnson & Johnson is a large healthcare company spanning pharmaceuticals, medical devices, and consumer health products, and a classic dividend grower that has raised its payout for many years. Steady medical demand regardless of the economy has earned it a defensive reputation in down markets. Yet over the 20 years from July 2006 it fell along with the broad market through the financial crisis, COVID, and the rate-hike era, and it also swung on company-specific troubles such as talc-powder litigation. In 2023 it spun off its consumer segment as Kenvue. This scenario covers the 20 years from July 2006 to July 2026.
Interpreting the result
Dollar-cost averaging invests the same amount monthly to smooth your cost, and a relatively calm dividend stock like J&J can be a bit easier to hold psychologically through declines. But despite the 'defensive' image, a single stock carries its own risks - litigation, regulation, spin-offs - and can drop sharply regardless of the market. On the result screen, check your ending value along with the maximum drawdown during the period, how long it stayed below your contributions, and the recovery time, and note that dividend taxes are not reflected.
Caveats & limits
This is a simulation of a single stock - Johnson & Johnson - that happens to have survived and become well known, and past performance does not guarantee future results. The fact that this one worked out says nothing about how other individual stocks will do: countless companies that listed in the same era and then failed or lagged never appear here, which is survivorship bias. A single stock carries far deeper maximum drawdowns, longer periods underwater, and concentration risk - if the business breaks down, it may never recover. Taxes (capital gains, dividends), trading fees, and the KRW/USD exchange rate are not reflected, so real returns differ. This is not a recommendation of any stock; it simply shows what already happened.

Frequently asked questions
With 300,000 KRW a month for 20 years, how much do I actually invest?
You contribute 300,000 KRW each month for 20 years - about 240 installments in total. The result screen shows both your total contributions and the ending value, and what matters as much as the final figure is how far it fell and recovered along the way.
How is a single stock like Johnson & Johnson different from indexing?
An index (e.g., the S&P 500) spreads risk across hundreds of companies, while a single stock concentrates it in one. When it works it can far outpace the index, but if the business stumbles the maximum drawdown is deeper and the time underwater is often longer. Always check the max drawdown, loss period, and recovery time.
Does this result include taxes, fees, and exchange rates?
No. It reflects share-price movement only; capital-gains and dividend taxes, trading fees, and the KRW/USD exchange rate are excluded. Your real brokerage return will differ from the displayed figure because of these.
