4. A Liquidity-Based Stock Network (with Zhenyu Gao and Da Tian), 2016 
    - CICF 2017

Stocks are connected through common ownership of financial institutions. Firm shocks can be transmitted and amplified through these interconnections, aggregating into market level fluctuations. We formalize this intuition by estimating a parsimonious model using mutual fund holding data. The model allows us to quantify the aggregate outcome of propagation of firm level shocks through the network. Using earnings surprises as a proxy for firm shocks, we find that our model's aggregation is significantly correlated with the aggregate market return. Also, the network structure estimated by our model can predict subsequent volatility of aggregate market returns and forecast the volatility of and correlation between individual stocks' future returns.

I test the hypothesis that the use of leverage by market speculators can increase the likelihood and magnitude of a crash in asset prices. Using a novel leverage measure derived from public filings, I find that stocks held by highly levered hedge funds subsequently have more negatively skewed returns than stocks held by less levered funds. This finding extends to the aggregate U.S. market index. I relate this effect to financial distress and find evidence that highly-levered funds are more likely to fire sell long positions when experiencing adverse economic events, including negative fundamental shocks to the assets they hold and funding liquidity shocks.
