I mean... if you think that data from 100 years ago is relevant, you do you. That's just goofy and I obviously won't change your mind. I can't think of much from a century ago that would be relevant in today's world, and aggregate stock performance is especially true. We are much more global, technological, safer, etc. I think a better question is why you think data from a century ago (especially relative to business performance in a totally different business world)? It's pretty hard to explain why something isn't...

It's a simple article to convince people that investing is good, but specific timing the market is difficult and unnecessary. Critical thinking.

And yeah, this isn't "advanced investing" or anything. It's a forum for any and all investors. Stop trying to gatekeep an investing subreddit lol, yikes
