Pre-trade hedging: Evidence from the issuance of retail structured products

Brian J. Henderson, Neil D. Pearson, Li Wang

Research output: Contribution to journalArticlepeer-review


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 show this behavior is intentional by exploiting variation in the design of structured equity products (SEPs). We find positive abnormal returns on SEP pricing dates for which issuers benefit from altering closing stock prices but no such returns on pricing dates of otherwise similar SEPs. We also show that large buy trades near the close of trading are more frequent when SEP issuers have incentives to alter closing stock prices.
