  • ITG’s size-adjusted spread (SaS) cost estimates provide guidance on the anticipated costs associated with instantaneous spot trade executions, measured relative to the prevailing mid-quote rate at the trade time. The underlying data for our model contains dealer quotes from 6 global banks and 5 major ECNs. By varying the manner in which we consolidate the limit order book across trading venues / liquidity providers, we are able to reflect different trading styles and credit tiers as well as varying degrees of sophistication of market participants. The use of the empirical limit order book enables us to construct cost estimates for instantaneous trading at various consolidation levels, deal sizes, as well as at various times of the day.

The double volume caps are likely to result in six-month dark trading suspensions for many stocks, increasing market complexity around trading suspended stocks and tracking the status of each stock.

  • The new closing auction session (CAS) on the Hong Kong exchange is showing encouraging signs of increasing stability on the exchange. The launch on July 25, 2016 went without major issues, and data in the first three weeks suggest that the mechanism is doing its job and averting the dreaded “close volatility.”

    CAS volumes have stabilized at around 5% of daily volume, with a rebalance peak of 13% of daily volume. More than 70% of stocks closed within ±20 bps of the reference price and 98% of stocks closed within 1%.
