Well I agree investing has some degree of speculation.
However investing consists primarily of finding instruments with good fundamentals (not just price and volume).
Most trading these days are primarily based on frontrunning investors(mutual funds, some hedgefunds, individual investors, institutional investors). This is not something that is sustainable. If it continues for long, no investors will be left. The wall street system in my opinion was created to efficiently transfer wealth to where its best utilized, and reward those to try to do so.
The current environment doesnt reward those who try to invest, but rather rewards the frontrunners.
In my opinion the huge increase in trading vs investing over the past couple of decades, maybe partially responsible for the decline in the US economy.
