Not exactly first day or last day. I tend to sell one to two days before ex-date for BIL and buy on the ex-date or one day after it. You may refer to BIL ETF's distribution schedule here:
https://www.ssga.com/library-content/produc...on_Schedule.pdf and mark down the dates on your calendar (take note ex-date for December is unusual as it's in the middle of the month, plus no distributions/ex-date(s) in January).
I notice there are some nuances in buying/selling BIL ETF. Usually there is an uptick in the ETF price (i.e., premium over NAV)
TWO days before ex-date rather than ONE day before ex-date. (Tail risk management?) And in occasions like US debt ceiling crisis, "smart money" usually trade even earlier. In any case, I look at my IRR, if the number moves up by several more basis points than the usually daily movements and it's very close to ex-date then I will follow "smart money".

Actually, if you think through, there's "economies of scale" in choosing to buy+sell around ex-date vs hold and let Uncle Sam tax 30% out of the distributions.
The reason is simple: WHT is 30% of distributions, which is dependent on how many units of BIL ETF you hold. However, brokerage fees for buy+sell is (almost) fixed at 0.35-0.45 USD per trade regardless of how many BIL units you hold (assuming you don't trade often with other counters).
I did some dirty calculations last year. You can have fun playing with this Excel file. I used previous distributions and compare the opportunity costs of either holding (no trade on ex-date) vs trading on ex-date.
For several thousand USDs the savings are probably to the tune of few cents, but for those with thousands of BIL units, the savings start to run into 1 to 2 order of magnitudes in USD. Also, one should take into consideration of time value of money. The distributions of BIL are paid not on ex-date but about 5 days later whereas buy+sell means money gets "reinvested" within 1-3 days. Minuscule savings I know...

In another news, ASNB/PNB has sent me the full list of investment for ASM1. See if you can find any counters that interest you here:
https://forum.lowyat.net/index.php?showtopi...ost&p=107438507Based on the schedule you sent me it seems like your buy will be 1st or 2nd of the trading month while you would sell around 25th of every month? Correct me if I am wrong I this assumption
