Since this is my first experience with Treasuries, I’ve set up a simple 4-week T-bill with automatic rollover. I’m curious whether there is any downtime where funds are not earning interest between the auction date and settlement date.
In other words, even with auto-rollover enabled, are there one or more days between transactions when funds sit idle and do not earn anything?
How does this compare to holding a Treasury ETF such as SGOV?
