Why could the bid/offer spread be wide for MacroShares?
MacroShares are a relatively new security structure, and may be linked to assets classes or economic indictors that otherwise have limited access and/or liquidity. Generally, as the number of MacroShares outstanding and market participants increases, bid/offer spreads should diminish, making the market more efficient. As with any security, always use prudent judgment when entering buy and sell orders, using limit orders whenever possible.
