Why this period and asset
March 2000 was the moment the dot-com bubble peaked and began to collapse. Enthusiasm for internet companies had run to an extreme, and as names with no real earnings fell one after another, the Nasdaq declined sharply over the following years. Investing a lump sum at this point means facing head-on the worst-case script of buying at the top and watching it break down immediately afterward.
Interpreting the result
This case shows how the outcome unfolded even when you entered at the worst possible time and held for a long stretch. Along the way, though, you had to endure a very large maximum drawdown and an extremely long stretch underwater, with your principal below cost for years at a time. The recovery period was also long, so it was easy to lock in losses if you sold when shaken. What matters is less that the result eventually recovered and more whether you could actually withstand the large drawdown and long recovery in between.
Caveats & limits
This result is a hindsight simulation of one specific worst-timing case, and there is no guarantee that every peak purchase recovers. It is a simple calculation that ignores taxes, fees, and currency effects. As a dollar asset, the outcome in won terms shifts with the exchange rate. Past recovery paths do not mean the future will repeat them.

Frequently asked questions
Does buying at a peak always mean failure?
Buying at a peak raises the odds of enduring a large drawdown and a long stretch underwater. This case is just one path that recovered after holding for a very long time, not a guarantee that every peak purchase recovers.
Since it recovered in the end, can't you just hold on?
The stretch underwater and the recovery period were both very long. If you need the money or cannot hold on emotionally, you lock in the loss, so 'just hold and it recovers' cannot be generalized.
Is a lump sum or monthly investing better?
In a sharp drop right after a peak, monthly investing keeps buying at lower prices throughout the decline and lowers your average cost. In a rising market a lump sum can do better, so neither is always superior.
