Monex Group Inc. is seeking more business from Japan¡¯s growing ranks of day traders in a bid to catch up with other online brokerages.

¡°Even if the investor pie for Japan¡¯s stock market doesn¡¯t increase, we¡¯re going to muscle in on the huge business that competitors are doing with active traders, an area where we¡¯re weak,¡± Monex President Oki Matsumoto said in an interview in Tokyo.

Matsumoto said he wants about 20 percent of the nation¡¯s day traders as customers within three years, but did not disclose his firm¡¯s current market share.
