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.

in oct 1993 forward Norgate data using chatgpt:
Untimed comparison
Metric Top5 12M Mome Top10→Top5 ADV20/ADV700 Difference
CAGR 23.09% 20.39% -2.70%
Max DD -67.86% -51.11% +16.75 percentage points better
Recovery 1190 days 1155 days 35 days better
Sharpe 0.774 0.871 Much better
Ulcer Index 25.39 17.30 Much better

Timed comparison (SPY > 325d SMA)
Metric Top5 12M Momentum Top10→Top5 ADV20/ADV700 Difference
CAGR 23.25% 18.23% -5.02%
Max DD -43.26% -33.06% +10.20 percentage points better
Recovery 1703 days 154 days 1549 days better!
Sharpe 0.819 0.921 Better
Ulcer Index 19.15 11.30 Much better

So if someone cared primarily about:

sleep-at-night factor
drawdown
time spent underwater

the ADV20/ADV700 version is actually impressive.

The most surprising number is not the drawdown; it's the recovery time:

Timed 12M momentum: 1703 days
Timed ADV20/ADV700: 154 days!

That's roughly 4.7 years faster recovery from the worst drawdown.

If I saw these numbers without knowing the strategy, I'd conclude:

ADV20/ADV700 is acting like a quality filter. It is sacrificing some of the explosive winners but avoiding a lot of the catastrophic collapses.

So far people who are willing to sacrifice 5% cagr, to get recovery in 6 months from their worst, drawdown, this is the way to go.
