ヾ(◍°∇°◍)ノ゙你好同学,
execution risk
交易慢了(在implementation shortfall中可拆分为delay cost和trading cost),以至于买的贵了,卖的便宜了
Execution risk is the adverse price impact resulting from a change in the fundamental value of the security and is often proxied by price volatility. 执行风险是由于证券的基本价值发生变化而带来的不利价格影响,通常会受到价格波动的影响
market impact
交易量较大,订单对市场造成影响之后,以至于买的贵了,卖的便宜了。
Market impact is the adverse price impact in a security caused from trading an order and can represent one of the largest costs in trading. 市场冲击是交易订单对证券产生的不利价格影响,可能是交易中最大的成本之一
