Members of Euronext, liquidity providers will undertake, as they already do for Eurolist stocks, to offer simultaneous bid and ask prices for the shares of publicly traded companies listed on Alternext. They must respect a minimum quantity, defined by either the number or the value of shares, and a maximum bid/ask spread, generally defined as a percentage.
Following the adjustments to the market model that took effect in January 2006, this will further enhance the liquidity of stocks listed with Alternext.
