[Computer Vision for Firm Networks and Spillovers](https://bm.hkust.edu.hk/bizinsight/2025/12/computer-vision-firm-networks-and-spillovers)

Many investors focus on either individual companies or broad market factors like value and size. But our research reveals a powerful middle layer: the network of connections between stocks.

[Stock Market](https://bm.hkust.edu.hk/bizinsight/tag/stock-market)

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

[Betting on Inflation Through the Bond Market](https://bm.hkust.edu.hk/bizinsight/2018/10/betting-inflation-through-bond-market)

A conventional theory about US Treasury bonds is that when there is uncertainty about inflation, the yield curve should get steeper because investors demand a higher premium for the risk of holding long-term bonds, as opposed to less vulnerable short-term ones.
However, recent evidence suggests this yield curve effect may not be happening and this has now

[Market Disagreement and Stock Returns](https://bm.hkust.edu.hk/bizinsight/2015/09/market-disagreement-and-stock-returns)

[Lessons from the Chinese Warrants Bubble](https://bm.hkust.edu.hk/bizinsight/2014/09/lessons-chinese-warrants-bubble)

History is scattered with spectacular asset price bubbles, from the Dutch tulip bubble of the 1600s to the Internet bubble of the late 1990s. These bubbles have been studied in minute detail to understand how and why their price came to exceed their fundamental asset value, but the studies have been disadvantaged by incomplete information and hindsight. What
