Most people glanced at the Hong Kong weather forecast and then went on with their day.
But one trader noticed a market: whether Hong Kong temperatures on July 17 would reach 30°C—at the time, the market price was only 1.8 cents.
He spent $35 and bet on “it will reach.”
As it turned out, the temperature that day really hit 30°C.
In that instant, his $35 became $1,935.
Profit: +$1,876
Return on investment: 5,360%
