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.

There's a scene in a Danny Divito movie where somebody make a snide smarmy insult to Danny's character. Dannny's comeback was putting on a self-deprecating little grin, waved his hand above his head, and said "Whoosh" that went right over my head.

This reminds me of that.

Theta? Alpha? Corpus? I haven't read the book and I have no idea what those mean.

I was looking for the set of mechanical rules of when to buy/sell and how to decide how much to buy/sell. Not the formulas--I can figure those out myself.
Something along the lines of: "If the stock drops X%, compute Y as {formula} and buy $Y worth of stock..."

Here's an example I found at random on the internet.
1) At the start of every week, check the 30-week change of ETF-A and ETF-B.
2) If neither of the ETFs are returning more than 3% in 6 months, do nothing.
3) If one or both ETFs are returning more than 3%, invest your entire position in that ETF.

here's what I gleaned from that guy's descriptions

Ugh. So the guy didn't actually lay out the rules for his strategy? Just made some ambiguous generalities with fancy names? Ugh.

Mark, it seems like you have the book. Does he list the concrete rules, or it is just vague handwaving?
