People make x money. X money is generally used for fixed necessities. 60% of ones general income is normally used for housing. Another x amount for food, transportation, and clothing. Then the remainder is discretionary income.
So outside of housing which I believe is a dead end to nowhere as an investment compared to other assets, one has to find out where the other 40% f money is going to spend meaning which food is going to be eaten, which form of transportation is going tobe used as in cars bought and gas used, as well as which clothing can be bought.
The next part is then finding the item that continually gets bought as in UGGS for the last 9 years but for some odd reason being short term "problems and impacts" the company value gets beat to $$$$ and one gets the oppurtunity to buy one of the most popular brands in the world that makes excellent cash and projecting more in the future but trading at just 15X foward earnings and 19 current.
