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.

10 years back is 2016. That period has been mostly a bull market without ANY bear market. Just a couple of shortish corrections.

Any backtest which doesn't include at least the 2008/2009 bear market will be telling you sweet nothings


Paraphrasing, all good stocks go up for the same reasons, poor performing stocks go down for different reasons.

Would a backtest that included the Dotcom bust be relevant to the GFC bust? I have not checked to see if this is true. Does anyone have insight on this. Having now just contemplated RayVt's statement, I am not sure including the GFC decline helps selection of a screen that will perform in the next major decline. I can only think that something like BCC protects you in a decline and then select screens that do well in a bull market.
