The week's question
In December 2024, in the thread "Re: BRK: Why Not XOM?", BreckHutHigh asked the members: "What about the long road trips with kids?" 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.

If you use 9 mo momentum on the market's top 100 stocks not in the Nasdaq100, 5 stocks monthly, the result is NOT GOOD. gtr1.net: GTR1 Backtester


Why does it default to a start date of 1997/09/02 ? It must be something about the MktCap, because when you delete that it goes back to 1985/02/01 which is the start date it uses for "nas100.a". Weird.

When I look at these screens with a lot of short-term trades in a taxable account, I assume that the tax reduces the CAGR by 25%. That is, 25% of the gain gets whisked off by the IRS each year.
Of course, these screens are best done in a Roth IRA or even a regular IRA.

The 52 week momentum top 5 HTD 12 has a CAGR range, min & max, of 24.1% & 29.6%. Avg 27.4%.

When you pull "Portfolio Values: Download daily portfolio values", the initial value for all cycles is $5. The final values range from $33,780 to $196,136, with median $108,192.
(For comparison, VFINX (S&P500 index) final value is $382. BRK-A is $2,718.)

I load the *lowest* cycle into the spreadsheet which computes the statistics with & without timing. So presumably you can expect to get a better return in real life.

Today I made what use to take me 6 months working; thank you momentum strategy!
Amen.
Not so fun on the days when you lose the same.

But remember the days just a few weeks ago when people were running around with their hair on fire proclaiming "the crash is here!!!!!!!" ? Good times, good times.
