What if you bought Sony at its PS5-hype record high?

Why this period and asset
After the PS5, launched in November 2020, became so popular it sold out, Sony's shares rose on gaming-earnings hopes to a record closing level on December 17, 2020. It was a symbolic moment — the first time above 10,000 yen since 2001. It is a case of a hit product feeding straight into a stock's record high.
Interpreting the result
A product selling well does not always make that moment a good buy price. In the metrics below, see the current value and XIRR, but also check the maximum drawdown and loss period after the record high. Compared with Toyota (another Japanese flagship) in the related scenario, you can see how paths differ by stock even within the same market.
Caveats & limits
As a single stock, be mindful of survivorship bias. Sony is JPY-denominated, so for won-based investors the JPY/KRW rate additionally affects results. Figures use adjusted close, exclude fees and taxes, and past results do not guarantee the future.
