Abstract
Insider trading plays a significant role in financial markets and how markets respond to new information.
Informed high-frequency traders pose a major risk to liquidity providers in financial
markets due to adverse selection, which can result in market failure. To mitigate this risk, some
exchanges have implemented speed bumps which delay trades. Using trade and quote (TAQ) data
of 45 stocks on the NYSE American and the NASDAQ from May 2017 to August 2017, I identify
the impact of a trading delay of 350 microseconds on the probability of informed trading for the
NYSE American using difference-in-differences estimation. I find a statistically significant decline
in the probability of informed trading after the implementation of the speed bump on the NYSE
American stock exchange.
