The stock market game is played under uncertainty. You are not totally certain of what the future may bring. However, if you take a long term view of things, you could look for "stuff" that does make sense, and might most assuredly continue in the future.
I do expect, with a very high probability, that tomorrow there will be more people on the planet. I can not be certain on a day to day basis, but I do know I will be right almost every day of the year since it will require a huge disaster for that statement not to hold. And those "events" do not happen every day.

This is part of my post-test analysis of the last three articles I wrote (see list below). All the tests were ran on Quantopian servers using their data under the same conditions as everyone else. I used a slightly modified version of the program found on their site.
The original cloned program used (The SPY who loved WVF) showed a 22.43% portfolio CAGR over its 6-year test. And this, while using 3x leveraged ETFs. If you did the math to convert the thing to a no leverage scenario, the CAGR would drop. There were no leveraging fees in this ETF scenario since leveraging is included by design. But, this still made it a 3x leveraged portfolio.
