Why this period and asset
June 2021 was when the KOSPI climbed to around the 3,300 level, an all-time high. Right afterward, the domestic market corrected amid rate hikes and external uncertainty, and it then traded in a long range without a clear new high. It shows how a domestic index can move sideways for a long time after a peak.
Interpreting the result
This shows the path of entering near a peak in Korea's benchmark index. The maximum drawdown was not small, and the stretch underwater and recovery period ran long. Unlike U.S. indexes, in a stretch that trades sideways for a long time without a clear new high, you may have to endure not only a large drawdown but also a tedious, long recovery. It should not be generalized that a specific index is bound to reclaim a new high.
Caveats & limits
This result is a hindsight simulation of one specific peak and does not guarantee recovery. A domestic index too can move sideways for a long time, stretching the time underwater. It is a simple calculation that ignores taxes and fees. The past does not guarantee the future.

Frequently asked questions
Does buying at a peak always mean failure?
Buying at a peak raises the risk of a large drawdown and a long stretch underwater. A domestic index in particular can trade sideways for a long time without a new high, so recovery is not guaranteed.
Since it recovered in the end, can't you just hold on?
The domestic index had stretches trading in a long range without a clear new high, so the time underwater and recovery period can be long. Generalizing 'just hold and it recovers' is difficult.
Is a lump sum or monthly investing better?
In a long sideways or declining stretch, monthly investing can lower your average cost. In a rising market a lump sum can do better, so neither is always superior.
