The week's question
In March 2025, in the thread "Re: OT, out", Umm asked the members: "Do you think it is because America is made up of magical soil that makes businesses based in America magically profitable?" This week it is put to everyone again. The button below opens the small thread re-asking it - read what others have said so far, then give your own answer as an ordinary reply.

And looking at the data, it really was only trading 5 days before the end of the month (using the 6th-to-last day close to calculate momentum and timing trigger) was why it looked like the new possibility of trading earlier had "weakened" since 2000.

Trading on the last day of the month, or the 2nd to last day, still were excellent and were improvements to the 1st of the month.

So my conclusion now is: trade on either of the last 2 days of the month using 1 day earlier from the day you trade to find closing prices to do calculations of 9 month momentum and (if you use my timing rule) the timing rule.
