In my opinion this is a much better article on the subject. http://www.bloomberg.com/news/articles/2014-07-21/renaissanc... Essentially the US has a few different taxes you can pay as an investor. There is a short term tax on trading profits and a longer term holder tax for "investors" which is lower. This obviously creates a situation where people will do their best to make their trading fall into the later category…
The rules are deeply arbitrary, and goes to the nature of financials as being rather abstract concepts with arbitrary definitions. I buy stock in a firm, that firm makes a lot of profit, but I don't liquidate my position. How is that different (short-term vs long-term gains) from me selling their stock and buying another stock? It's even the same word: A retail business sells its stock (product), and sells it's stock…
How is this not "logical" ? Can you explain better?
