WASHINGTON — The number of municipal securities that traded in 2011 remained largely unchanged from 2010 and the volume of trades of less than $100,000 rose during the period, suggesting that more retail investors may be buying and selling municipal bonds.

The Municipal Securities Rulemaking Board’s 2011 Fact Book, released Wednesday, shows there were 10.4 million municipal security trades in 2011, down slightly from 10.5 million in 2010.
