"Our baseline finding is that both congressional leaders in their pre-leadership years and their matched 'regular' members underperform the benchmark by similar magnitudes"
"Earlier studies of lawmakers’ trading by Ziobrowski et al. (2004 and 2011), found their portfolios to outperform the market. However, this conclusion is reversed in later studies. In particular, Eggers and Hainmueller (2013) and Belmont et al. (2022) document the opposite—members of Congress underperform the market during 2004-2008 and 2012-2020, respectively."
I guess the title of "Congress members suck at trading stocks, but suck less once in leadership positions" was already taken
