Do traders benefit from riding the t-bill yield curve?

Studies show that riding the Treasury bill yield curve consistently provides higher returns than a matched-horizon buy-and-hold strategy and this article confirms earlier findings. Using Federal Reserve (FRED) interest rate data on 91- and 182-day T-bills and GovPX interdealer tick data over the period January 2001-September 2007, the authors find that no interdealer sales of 182-day T-bills occurred at the time needed to complete a ride, suggesting that no trader benefited through the interdealer market.They also show that selling the seasoned bills at the end of the ride in the new 91-day on-the-run secondary market or its when-issued market would have provided higher returns than the returns computed using the FRED data. But to generate $1 million of annual riding returns would require capturing 85% of the available market volume every week. The authors conclude that riding the T-bill yield curve continues to appear viable across time because of transaction volume limitations.
