Most of our members are US-based investors that are looking for the highest possible after-tax income. That means that we either generate a nominal amount high enough to cover tax liabilities and still leave us with the income we need, OR, generate that income through tax-exempt instruments like municipal bonds. We don't provide much coverage on munis, but in the event our members have an interest, we will provide an article on a periodic basis.
Because our members reside all over the United States, we don't necessarily focus on individual bonds issued by specific states.
