23 January 2020: China locks down Wuhan
Chinese authorities sealed off Wuhan, a city of about 11 million people, to contain a new coronavirus. Trains and flights were halted, and the lockdown soon spread to surrounding cities. Western markets barely flinched at first; the S&P 500 would hit a record high a month later. Then the virus went global and stocks fell faster than in any previous crash. Distant problems have a habit of arriving.
The lesson: Markets often underreact to slow-moving risks until those risks are suddenly impossible to ignore.
What it meant for investors
$1,000 in Shanghai Composite at the start of 2020 → $1,279 today, vs $2,092 in the S&P 500.
We start the clock at the start of 2020, the year it happened. That is 1.3 times the money, but $814 less than a plain index fund made over the same years.
What Shanghai Composite teaches: Rapid economic growth does not guarantee stock market returns, because dilution, governance and the price paid decide what shareholders actually receive.
