SGX to launch price collars for market auctions

Following a public consultation, the Singapore Exchange (SGX) plans to introduce price collars during the securities market opening, midday and closing auction routines.

This is to guard against the risk of severe price dislocations during auctions, it said on Thursday.

The price collars, or bands, comprise: plus/minus 30 per cent of the reference price during the opening auction; plus/minus 10 per cent of the reference price during the midday break and plus/minus 10 per cent of the reference price during the closing auction.

The reference price for the opening auction is the last traded price as at the end of the previous market day, while that of the midday break and closing auction is the last traded price earlier in the same market day.

The price collars will apply to all components of the Straits Times and MSCI Singapore Indexes, said SGX. They will also be effective on stocks, and units of stapled securities, Reits and business trusts, funds, as well as exchange-traded funds with a price of at least $0.50.

Another option considered had been to extend the auction routine by four to five minutes if the indicative opening price during the auction moves beyond a certain threshold. Twelve parties - including associations - responded to the public consultation. Most respondents preferred price collars as they are easier to understand than time extensions, easier to implement and more cost-effective, said SGX.
