Abstract

We study the conflict of interest that arises when a universal bank conducts proprietary trading alongside its retail banking services. Our dataset contains the stock holdings of every German bank and those of their corresponding retail clients. We investigate (i) whether banks sell stocks from their proprietary portfolios to their retail customers, (ii) whether those stocks subsequently underperform, and (iii) whether retail customers of banks engaging in proprietary trading earn lower portfolio returns than their peers. We present affirmative evidence for all three questions and conclude that proprietary trading can, in fact, be detrimental to retail investors.

Keywords: Conflict of interests, universal banks, proprietary trading, retail investment, retail banking
