This list ranks stocks on Asian exchanges by their percentage gain over the last 21 trading days and shows the top 100. Short-term leaders often keep leading, so many traders scan the best performers this month for continuation setups, while others look for overextended names to avoid. Prices are in each exchange's local currency, and the list covers stocks traded in Tokyo, Hong Kong, Singapore, Seoul and Jakarta with at least about US$0.7 million in average daily trading value.
