One of the easiest ways to mess up good trades is to focus too much on the indices. Because of the intense focus on the DJIA by folks in the business media, individual investors tend to think too much about the macro concerns that are part of the discussions. There is nothing financial pros enjoy more than pontificating on the state of the world and how it impacts the stock market.
Stocks do tend to move in correlated fashion at times but the level of correlation will vary wildly. Typically in a bad market, almost everything falls in tandem and fighting the trend is especially difficult. However, like Jim Cramer has said quite often, "There is always a bull market somewhere."
That is an excellent reminder that we shouldn't let the media's focus on the big picture prevent us from finding opportunities. There are always a few out there and quite often the best ones will give even better entry points when attention is centered on issues such as the Fed, trade wars or politics.
It is very easy to overcomplicate trading and investing. It isn't necessary to formulate complex macro arguments or to calculate discounted cash flows and projected GDP. Good opportunities always exist and your focus should be on finding them.
Many people worry about bear markets, but that has never been one of my concerns. I know that whatever the market does I will be able to find some new opportunities. Don't let the economic forest blind you to the opportunities in the individual trees.
