I added a Seeking Alpha article with a detailed analysis of NBB which invests in “Build America Bonds”- good for IRA’s. A bill has been introduced to reinstate the Build America program, but the chance of passing seems pretty low.
I wonder about the politics here. Many retired senior citizens are large municipal bond holders and are Republicans, but the Republican party seems more concerned about the Tea Party wing. But a high percentage of seniors vote. If the muni bond holders vote their wallets, they may switch to the Democrats.
There is another article discussing whether stories on Jamie Dimon and Vanguard may have signalled a bottom in municipal bond prices.
