After climbing 188%, one of the world's hottest stocks tumbles in S Korea

Celltrion fell 9.9 per cent on Friday after its fourth-quarter revenue and earnings missed estimates

After climbing 188 per cent over the past year on volume that topped that of Tesla Inc. and Citigroup Inc. at one point this month, Celltrion abruptly reversed course last week.
