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.

But does anyone know how Nasdaq NHNL works prior to the existence of the Nasdaq exchange?

step0 in [NHNLDiff] filters the exchange. Before 19731217, step0 passes all stocks (because 3==3). After 19731217, step0 filters to NASDAQ stocks.

step0:
if [Mkt Date] < 19731217:
TRUE
else
[Exchange] == NASDAQ
