Do you look up your stock prices in the WSJ tables? Mako's point isn't that print is obsolete, it's that printed daily snapshots of constantly-updated data are.
(Which I 99% agree with, there are some rare cases when you want old snapshots that haven't been subsequently revised, but does that mean we need to keep printing tables in every copy of every day's paper?)
I suspect the average investor would do better focusing on week old stock data that the knew wasn’t being updated than trying to keep up with the market using sub par quotes.
Assuming the goal is to buy and hold for 10+ years, recent changes should be irrelevant.
That's me. I log into my brokerage every few weeks to have a quick peak and make any necessary tweaks. And then I log out and don't think of it. I don't keep an app on my phone because I know it would distract me.
