Passive Efficiency - Exploring Stocks' Return, Risk, & Efficiency Through Index Investing in Europe
(2024) NEKN02 20241Department of Economics
- Abstract
- This study investigates the consequences of stocks being included in an index, in terms of
returns, risk, and pricing efficiency. We examine the European stock market, utilizing the broad
STOXX Europe 600 index, which, to a large extent, has been overseen by previous research.
Over the recent period 2013-2023, we document all additions to the index and collect fund
ownership data, classified as index (passive) and active, on all stocks before and after the index
inclusion. Employing a two-way fixed effect panel regression, we examine potential effects in
relation to fund ownership. The study suggests that active fund ownership is significantly
related to positive stock returns, as seen by both the arithmetic and geometric mean... (More) - This study investigates the consequences of stocks being included in an index, in terms of

Over the recent period 2013-2023, we document all additions to the index and collect fund

relation to fund ownership. The study suggests that active fund ownership is significantly
related to positive stock returns, as seen by both the arithmetic and geometric mean return.
Concerning stocks' risk, measured by volatility and beta, we find a significant positive
connection to index fund ownership. Regarding pricing efficiency, tested through the variance
ratio test, we observe insignificant results, consistent with previous research. In essence, our
findings suggest that inclusion in an index does not harm the efficiency of the pricing
mechanism. However, a potential side effect is an increase in idiosyncratic risk as index
ownership rises. (Less)
