Recent research argues that uncertainty about future stock borrowing fees is an impediment to short-selling and it explains the risk-adjusted performance of short strategies. One possible mechanism is that borrowing fee risk carries a risk premium. Since the present value of the uncertain...

We use data on signed option volume to study which components of option volume predict stock returns and resolve the seemingly inconsistent results in the literature. We find no evidence that trades related to synthetic short positions in the underlying stocks contain more information than...

We find evidence consistent with previously unrecognized market manipulation by broker-dealers. Specifically, we show that pre-trade hedging, which is distinct from front-running, alters prices at which derivative trades occur. We document that this behavior is intentional by exploiting...

This paper uses a novel dataset of Commodity-Linked Notes (CLNs) to examine the impact of the flows of financial investors on commodity futures prices. Investor flows into and out of CLNs are passed to and withdrawn from the futures markets via issuers' trades to hedge their CLN liabilities. The...

We use “tick-by-tick” quote data for 39 liquid U.S. stocks and options on them, and focus on events when the two markets disagree about the stock price in the sense that the option-implied stock price obtained from the put-call parity relation is inconsistent with the actual stock price....

We use retail Structured Equity Product (SEP) issuances to construct a new sentiment measure for individual stocks. The SEP sentiment measure predicts negative abnormal returns on the SEPs' reference stocks based on a variety of benchmarks including behavioral factor models and factors based on...

The question of whether and to what extent option trading impacts underlying stock prices has been of interest since options began exchange-based trading in 1973. Recent research presents evidence of an informational channel through which option trading impacts stock prices by showing that...

We use brokerage account records to study trading during the Chinese put warrants bubble and find evidence consistent with extrapolative theories of speculative asset price bubbles. We identify the event that started the bubble and show that investors engaged in a form of feedback trading based...

The question of whether and to what extent option trading impacts underlying stock prices has been a focus of intense interest since options began exchange-based trading in 1973. Despite considerable effort, no convincing evidence for a pervasive impact has been produced. A recent strand of...

There are a number of circumstances in finance where it is useful to estimate diffusion processes conditional on some event. In this paper, we develop the theoretical and numerical tools necessary to perform conditional estimation of diffusion processes within a generalized method of moments...
