TAIPEI Feb 26 (Reuters) - A unit of Taiwan's Yuanta Financial Holdings Co Ltd has not won the bid for a controlling stake in South Korea's Tongyang Securities , Yuanta Financial's spokesman Chuang Yu-de said on Wednesday.
Yuanta said earlier on Wednesday it will bid for the stake, without elaborating.
The move comes after Taiwan's top financial regulator, William Tseng, said recently that he would encourage brokerages to increase investments overseas in part because the Taiwanese market is crowded and fragmented.
