Let's say two seasoned house builders or contractors are talking to one other.
Person 1 tells person 2: "Hey dude you don't want to build a house there -- it would be really hard."
In that case there is a very clear non abstract idea of what "hard" means. And if it is not clear, person 2 can ask person one what he or she means. Person 1 can then go over the points: The weather there is bad, its hard to get supplies and labor, the owner doesn't know what he wants, the subcontractors in the area are bad, etc, etc. (I have zero experience in this area so just guessing.)
And then a discussion and debate about these points can take place.
When it comes to investments, and especially in investments in common stocks, the word hard comes up a lot -- however no one ever seems to question what that "hard" means. The discussion never goes beyond that statement. It usually goes something like: Picking individual stocks is hard, and you must be a genius or above average -- you should instead buy an index fund to be diversified, o and also choose your risk/ return whatever and also choose different assets.
I mean -- can anyone here honestly define the terms clearly?
I read the books (a lot if not all -- reread the good ones a lot as well). One of my Majors was finance. So I know what the terms mean or at least what the books say they should mean. I am not trying to play dumb and just be disingenuous and hackle from the crowd.
I really do think though that the discussion about common stock investing is clouded.
Some people in this thread said that they like index funds because they don't have to worry about picking individual companies. Or they are not interested in picking individual companies. They would rather spend the time elsewhere. That is a perfectly fine and valid answer. You don't need to know the details of every single advanced feature of our society to benefit from it.
However, saying that you like index funds versus individual companies because picking stocks is: hard, or you must be diversified, or you must have different asset classes, or you must have your preferred risk / return profile... is wrong if you don't define the terms beyond a superficial level.
It's wrong because, while the terms sound fancy, they are really just hazy abstractions which prevent clear discussion about the interesting details of investment and valuation.
Here are some questions:
What is risk?
Why is diversification good?
