Linking 10-K and the GICS - through Experiments of Text Classification and Clustering

Tingyue Gan, UC Berkeley

A 10-K is an annual report filed by a publicly traded company about its financial performance and is required by the U.S. Securities and Exchange Commission (SEC). 10-Ks are fairly long and tend to be complicated. But this is one of the most comprehensive and most important documents a public company can publish on a...

SEM217: Senyang Zhao, SWUFE: The Implication of Information Network in Market Quality and Market Reaction to Public Announcements

Tuesday, April 30th @ 11:00-12:30 PM (1011 Evans Hall)

The Implication of Information Network in Market Quality and Market Reaction to Public Announcements

Senyang Zhao, SWUFE

This research studies the role of information network in market quality and market reaction to public announcements. We propose in this article a three-period rational noisy expected equilibrium model by taking both public and private information into account with an embedded information network structure among...

Tingyue Gan, UC Berkeley: Linking 10-K and the GICS - through Experiments of Text Classification and Clustering

A 10-K is an annual report filed by a publicly traded company about its financial performance and is required by the U.S. Securities and Exchange Commission (SEC). 10-Ks are fairly long and tend to be complicated. But this is one of the most comprehensive and most important documents a public company can publish on a yearly basis. The Global Industry Classification Standard (GICS) is an industry taxonomy developed in 1999 by MSCI and S&P Dow Jones Indices and is designed to classify a company according to its principal business activity. The GICS hierarchy begins with 11 sectors and is...

Senyang Zhao, SWUFE: The Implication of Information Network in Market Quality and Market Reaction to Public Announcements

This research studies the role of information network in market quality and market reaction to public announcements. We propose in this article a three-period rational noisy expected equilibrium model by taking both public and private information into account with an embedded information network structure among market traders. Closed form expressions for market reaction and market quality are derived as a function of topological structure of the network and several novel results are revealed. The trading volume and price change have different responses to network connectedness. As network...

Farzad Pourbabaee, UC Berkeley: Robust Experimentation in the Continuous Time Bandit Problem

We consider the experimentation dynamics of a decision maker (DM) in a two-armed bandit setup, where the agent holds ambiguous beliefs regarding the distribution of the return process of one arm and is certain about the other one. The DM entertains Multiplier preferences a la Hansen and Sargent [2001], thus we frame the decision making environment as a two-player differential game against nature in continuous time. We characterize the DM's value function and her optimal experimentation strategy that turns out to follow a cut-off rule with respect to her belief process. The belief threshold...

Raymond Leung, UC Berkeley: Asset Insurance Premium in the Cross-Section of Asset Synchronicity

Any asset can use some portfolio of similar assets to insure against its own factor risks, even if the identities of the factors are unknown. A long position of an asset and a short position of this portfolio forms an asset insurance premium (AIP) that is different from the equity risk premium. We estimate the AIP by projecting a stock’s return onto the entire asset returns span using a machine learning method. Stocks least (most) synchronized with other stocks earn a monthly AIP of 0.976% (0.305%). Asset synchronicity is countercyclical: high consumption growth correlates with low average...

Robert Marquez, UC Davis: Financial Frictions, Foreign Currency Borrowing, and Systemic Risk

We present a novel explanation for the prevalence of foreign-currency borrowing in emerging markets. First, under limited liability, foreign-currency denominated debt acts as a state-contingent claim: Borrowers maximizing profits in local currency are partly shielded from large devaluations through bankruptcy, when repaying foreign currency debt is expensive, but pay higher rates in non-devaluation states, when repayment is relatively cheaper. Second, foreign- currency borrowing can improve firms’ incentives and reduce agency problems at the cost of higher systemic risk. The resulting...

Samim Ghamami, Goldman Sachs and UC Berkeley Center for Risk Management Research: Collateralized Networks

We study the spread of losses and defaults through financial networks focusing on two important elements of regulatory reforms: collateral requirements and bankruptcy stay rules in over-the-counter (OTC) markets. Under "segregated" collateral requirements, one firm can benefit from the failure of another, the failure frees the committed collateral of the surviving firm giving it additional resources to make other payments. In OTC derivatives markets, similarly, one firm may obtain additional resources upon the failure of another if it terminates its in the money derivatives with the failed...
