I analyze the price discovery, liquidity provision, and transaction-cost components driven by the real-time firm-specific news at the Paris Bourse. I find that the news impact depends on which type of news bulletin is released. Only news items causing extreme price disruptions such as earnings...

We show that High Frequency Traders (HFTs) are not beneficial to the stock market during flash crashes. They actually consume liquidity when it is most needed, even when they are rewarded by the exchange to provide immediacy. The behavior of HFTs exacerbate the transient price impact, unrelated...
