The time between order submission and order confirmation is crucial for high frequency traders as they risk slippage when latency is too high. We hypothesize that high latency in cryptocurrency markets implies correlations well below one across exchanges at high frequencies. To evaluate this...

This article analyzes asymmetric volatility effects for the 20 largest cryptocurrencies and reports a very different asymmetry compared to equity markets: positive shocks increase the volatility by more than negative shocks. We explain this atypical effect for financial assets with trading...

We investigate the price reaction of listed companies in response to blockchain-related announcements. The average abnormal return based on a global sample of 713 firm announcements is approximately 5% on the announcement day, with significantly higher returns for U.S. firms, smaller firms and...
