Thanks. For a second I thought I was chatting with someone you who knew what they were talking out. I appreciate you confirming you were basing your answer of something you read 10 years ago in a book, a book you can no longer find. The rest of your comment shows you didn't even study the basics of finance and economics either.
Dave, Hacker News has some of the smartest commentary I found on a News site. Questions on here regularly have people answering them where that person has experience, worked in that field professionally and have studied those topics in school and have degrees in them.
I realize this is the internet, expectations are low. People troll. Even if you wanted to help, why not wait a minute before answering to see if someone more informed or more experienced, than a book read 10 years ago will have answer. It's more a courtesy to the person asking as they get a better answer, and it stops you from looking like an idiot. Win-win.
Just wanted to add that Dave's notion is not quite as absurd as you make it out to be.
As you might know, daily rebalancing leveraged ETFs (say, 2x or 3x) are basically a bad idea for long-term investments, because they are (simplistically) short vol. So, they might outperform the (non-leveraged) index/ETF if vol is low and total return over the period is high. But typically, with normal or high vol, or over long periods, they underperform non-leveraged.
By analogy, a less-than fully invested ETF/trading strategy that's basically "0.7x" leveraged will beat the (non-leveraged) index/ETF in certain trading regimes (where total return over a period is negative or modestly positive, while vol relatively high).
