Quality and financial health

Financial health is average - GBAB passes 6 of the nine Piotroski tests, which passes the Sunday Scan's "6 or more" rule. The Financials tab on the Quote page shows which tests fail. The GLS Moat score is low at 3.3 out of 10, which says the ten-year record of revenue, earnings, margins and returns on capital has been inconsistent - growth and shocks rather than steady compounding.

Returns on capital are moderate - ROIC 5.7%, ROE 7.9%, ROA 5.5% - with debt at 0.40 times equity and a free-cash-flow yield of 7.3%.

The dividend yield is high at 12.16% (payout ratio 124%) - a payout above 100% of earnings, which is not covered by profits. A yield this size is often the market's way of pricing a risk to the payout, so the health score and cash flow matter more than usual.

Institutional ownership scores 4/10, insider activity 10/10 and Congressional trading 5/10 on the GLS smart-money scales.
