Why Do HFTs Use the Futures Market
研究高频交易者使用个股期货合约的经济动机，发现套期保值是主要原因，且监管提高最小合约规模削弱了其套保能力。
ABSTRACT This study attempts to investigate the economic motivation of high‐frequency traders (HFTs) to use single‐stock futures (SSFs) contracts. Using a novel intraday data set from the largest exchange of SSFs, with identifiers for algorithmic traders, we attempt to disentangle the hedging and information‐based trading motivations of HFTs in using this market. We find that hedging is the primary motivation for HFTs to use the futures market. We also find that the regulatory change of upward revision of the minimum contract size in the derivative market made it more difficult for the HFTs to use the futures to hedge their spot market exposure effectively.
