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.

lizgdal,

1. For each stock, calculate the ratio of the current price to the highest price over the previous 251 market days.


I hate to be so dense but this whole calculation is not about a bunch of stocks. I am trying to do a calculation based on a single stock (SPY) on a single date. I can calculate PriceToHighPriceRatio for SPY on a given date and I can decide whether to give B a value of 0 or 1 but that gives me one B value. There is nothing for me to sum up unless I take the previous date and calculate a second B value based on that date and the high price on the previous 251 days. Then do that again for all 251 previous days thus ending up with 251 B values to sum up. Is that what Robbie is doing?
