The German corporate governance system changed substantially over the last ten years. Meanwhile, ownership structures
of German firms changed significantly. The paper examines the phenomenon of changing ownership structures by
studying blockholdings of German large caps between 1997 and 2006. It examines the dynamics of blockholdings by
analyzing the evolution of free float and block trades, where at least 5% of voting rights change hands. Two findings
emerge. First, the authors find that free float increases from 65% in 1997 to 75% in 2006, mainly caused by German
financials and German government entities. Simultaneously, they observe a surprisingly high number of block trades: on
average 1.6 block trades per firm from 1997 to 2006. Second, the authors find that particularly individuals and German
industrials are guarantors for a stable ownership structure. German financials or German government entities as blockowners
increase the free float and the likelihood of block trades. Moreover, block trades are more likely to occur in firms
having foreign investors as owners. The findings are of interest with respect to the evolution of the so-called ‘Deutschland
AG’ but also with respect to the current anchor shareholder discussion
