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.

Sure. Mine is Excel 2003, seemed to upload to google sheets just fine.
Google: QQQ-daily-for-TQQQ-tracking - timing

Ah, I did make one mistake in my post. Since TQQQ inception there have been 15 trades, not 20. 2/11/2010 - 11/6/2025
4/2/09    Buy
8/31/10 Sell
9/20/10 Buy
12/1/11 Sell
1/18/12 Buy
8/9/12 Sell
8/16/12 Buy
1/31/13 Sell
3/5/13 Buy
4/12/16 Sell
7/12/16 Buy
1/9/19 Sell
3/12/19 Buy
3/31/22 Sell
1/27/23 Buy


TQQQ-qqq-timing tab computes the timing. Rows 91-122 have the signals, which are computed in columns E, F, and G. Col H has the
trades.
Col E shows if the QQQ close is the highest in the last 90 days.
Col F is the number of those that occurred in the last 90 days.
If that is zero, it's the "OUT" signal.

TQQQ tab has the B&H and Timed daily returns.

Tab QQQ-daily-3xO-O is a trial to simulate TQQQ before its inception. The best fit is actual 2.76X instead of 3X.
