More and more research suggests that the past return of one firm’s stock can predict the stock returns of other, connected firms—with momentous implications for firm networks and investors. “Such cross-stock return momentum is found among stocks connected by the same industry, supply chain, and geographic location,” explain Jialin Yu of HKUST and a colleague

This mechanism, which is substitutive to

The interest rate charged on business loans, known as the discount rate, affects stock prices. This is particularly important, given the fast rate increases by the Federal Reserve this year. However, traditional methods of calculating its impact are not sophisticated enough, according to HKUST’s Zhanhui Chen. To address this limitation, the researcher
