What if you started monthly S&P 500 DCA around Gangnam Style?
This uses real data to show what would have happened if you had invested 300,000 won a month into the S&P 500 (SPY) starting around July 2012, when PSY's Gangnam Style swept the world. It is a very-long-term DCA case using an easy-to-remember milestone as the start.
⚠️ Know the risk first
Even DCA has stretches where value falls below what you put in. This period includes the 2020 and 2022 declines; always review the maximum drawdown and loss periods.
What happened that day
On July 15, 2012, PSY's 'Gangnam Style' music video premiered, later becoming the first YouTube video to pass one billion views and a global sensation. Here it is used only as an easy-to-remember DCA start.
Why this date
A globally remembered public milestone is used as the reference for the 'DCA start date.' It does not mean the event caused the index's rise — it is simply an easy-to-remember date.

Why this period and asset
July 15, 2012 is the day PSY's 'Gangnam Style' music video premiered, later becoming the first YouTube video to pass one billion views and a global sensation. Using this easy-to-remember moment as the start, we assume you put the same amount into the flagship U.S. index, the S&P 500, each month from then. The roughly 14 years since include the 2018 correction, the 2020 COVID crash, and the 2022 bear market.
Interpreting the result
DCA spreads the same amount across each month, automatically buying more units when prices are low and reducing the risk of getting fully trapped at a single peak. A feature of this case is that the very early start means a long time compounding. In the metrics below, look at total invested (the sum of monthly contributions), the final value, and the cash-flow return (XIRR). Note that even DCA has stretches where value falls below what you put in, so always check the maximum drawdown and loss periods.
Caveats & limits
Gangnam Style is only an 'easy-to-remember date' and in no way implies this event caused the S&P 500's rise. Even index DCA has loss periods and does not guarantee the future. SPY is a U.S. index, so FX matters in reality, but this calculation excludes exchange rates, fees, and taxes (pre-tax). Always review the maximum drawdown and loss periods.

Frequently asked questions
Why use Gangnam Style as the start?
It uses a globally remembered public milestone as the reference for 'when you started DCA.' It in no way implies Gangnam Style caused the S&P 500's rise — it is just an easy-to-remember date.
Why does an early start matter?
The longer the horizon, the longer compounding works in DCA. Starting in 2012 accumulates about 14 years, a longer compounding time than later starts. But you must also see that it passed through several large declines along the way.
Does DCA mean no losses?
No. Even DCA has stretches where value falls below what you put in. The 2020 and 2022 declines fall within this period. Be sure to check the maximum drawdown and loss-period metrics below.
Are FX and taxes reflected?
No. SPY is a U.S. index, so FX matters in reality, but this calculation excludes exchange rates, fees, and taxes (pre-tax). KRW conversion and taxes would additionally affect actual results.
