Sammendrag
There are reasons to believe that there is increased popularity of trading in the closing auction
due to the growth of index investing. We use intraday trading data from the Oslo Stock
Exchange to examine and test the following hypotheses: (1) index investing drives closing
auction turnover, and the turnover of stocks in the OSEBX and OBX Index is significantly
higher during the closing auction relative to the remaining stocks on the Oslo Stock Exchange,
and (2) prices deviate at the close and reverse overnight. Our results show that the turnover of
stocks in the OSEBX and OBX are significantly higher than the remaining stocks during the
closing auction. Further, prices do deviate at the close and reverse almost entirely overnight.
Nevertheless, the use of the closing auction on the Oslo Stock Exchange might be more
influenced by opening trends of the American stock market than index investing.
To our knowledge, this is the first paper that analyzes the implications of the Oslo Stock
Exchange closing auction on underlying stocks and conducts analyses to investigate whether
index investing is related to the growth of trading during the closing auction.
