TOKYO -- Mizuho Securities will offer institutional investors a trading system guided by artificial intelligence that predicts the optimal time to execute stock transactions, a tool that could help shore up pension and mutual fund returns.
The AI developed by the Mizuho Financial Group unit will look at such data as outstanding orders, trading volume and past price changes to forecast how a given stock will move in 30 minutes to an hour. The system will execute an order earlier if it expects the price to rise, or later if it predicts a drop.
The service is slated to launch as early as late November. It will start out with the top 500 stocks by market capitalization on the first section of the Tokyo Stock Exchange, which are particularly heavily traded, and expand later. The system should improve results by about 0.01% of order size, according to Mizuho. The brokerage will not charge for the service.
While AI is an increasingly common sight in the finance industry, businesses that use it typically enlist technology companies to help with development. Mizuho instead spent hundreds of millions of yen to build its AI entirely in-house. "Since we're at a point where AI is commonplace, we'll need to refine it in accordance with our customers' needs," Vice President Masahiko Todoroki said.
