Quarterly GDP growth is nowcast from monthly indicators by 21 models under two ragged-edge treatments. Bridged imputes the target quarter's missing months with an ARIMA before estimation — the classic bridge treatment. Real-time builds each specification from exactly the indicator months observed at run time, with the state-space models absorbing the edge through the Kalman filter. The four ensembles — mean, median, trimmed mean of the best quartile by RMSE, and the single best model — are re-ranked under each run's information set. A nowcast only moves when the indicators feeding it move, so a flat stretch between releases is the tracker working, not failing.
