anonymity in the trading process. We confirm previous studies showing
that market liquidity improves immediately after anonymous
trading. Using the daily percentage of effective volume traded anonymously,
we show that the anonymity–liquidity relationship presents
a non-linear U-shape. We focus on the voluntary concealment of
broker identification introduced by the Spanish Stock Exchange in
October 2015. We conclude that, in our sample, anonymity increases
stock liquidity but at a decreasing rate; when a considerable part of
the effective volume is traded anonymously, additional percentages
of anonymous trading deteriorates stock liquidity.[+][-]
