Fair Value Reasoning:

According to official records from the Hong Kong Observatory (HKO), the maximum temperature recorded at the HKO Headquarters (Tsim Sha Tsui) on March 18 was 27.8°C. This reading falls squarely within the '27°C' option range (27.0°C to 27.9°C). As the day has concluded and this specific reading feeds into the 'Daily Extract' used for resolution, '27°C' is the definitive winning outcome. Although 27.8°C is close to 28.0°C, the market rules specify one-decimal precision, preventing it from rounding up to the '28°C or higher' bracket.

Arbitrage|Low Risk

Arbitrage Plan:

Buy Yes '27°C'

Plan Description:

This is a low-risk yield opportunity. The event has concluded with the temperature fixed at 27.8°C. Buying Yes on '27°C' (at ~99.45c) is effectively purchasing a certain cash flow at a discount. The only residual risk is an extremely rare data correction or dispute over the resolution source definition, but given HKO has already published press releases confirming 27.8°C, this risk is negligible.

2026-03-18 16:00 - 2026-03-19 00:00 (HKT), the price of '27°C' climbed from 77c to 99c, while '28°C or higher' dropped from 15c to under 1c. The reason is that with sunset, the diurnal heating cycle concluded, locking the final maximum temperature at 27.8°C. This eliminated the risk of temperatures rising further to breach 28°C, shifting market sentiment from 'probable' to 'certain'. 2026-03-18 12:00 - 2026-03-18 16:00 (HKT), the price of '27°C' skyrocketed from 32c to 87c. The reason was strong afternoon heating in Hong Kong, which quickly pushed temperatures past 26°C and towards 28°C, causing the collapse of lower-temperature options that had underestimated the warmth.
