Is there a hard threshold? Do high risk investments such as penny stocks qualify as gambling? Do low risk investments? Annuities? Bonds? CDs?
This comment got me wondering.
Is it more to do with the venue? Stock markets and real estate vs casinos and the lottery?
Were the MIT Blackjack Team gambling or investing?
Is this just another semantic hotdogs are sandwiches discussion or is there an agreed threshold?


Turns out “close to guaranteed” is in fact, not “guaranteed.”
Here’s my 25 how did they do:
(hint: they’ve all filed for bankruptcy at some point)
Again, look at the Nikkei from the 1990’s - that’s an entire index that was flat for 30 years. Hard to put off retirement for 30 years waiting for that index fund to pay off.
Don’t bother dying on this hill, son, there’s plenty of other, nicer hills to die on.
“All traded stocks” isn’t “Any traded stock”.
It’s all of them collectively.
The 1990’s was only 10 years. And that’s also just Japan, which again isn’t “All Traded Stocks”.
I don’t disagree with the general point of, “there’s no guarantee”. But I think you can make an argument that taking the safest course available to you is not gambling.
When talking about longer time frames you have to account for inflation, holding on to your money instead of investing it is a risk in itself, which makes this entire conversation about semantics.
