This might have gotten lost in the details. But I have noticed that the Baltic Dry Index is a great tool for assessing how the global trade is faring. I wonder what other metrics are out there that the majority of the traders and investors use. If you know of any, then please feel free to share.
Apparently there are other shipping index(es) as well. So, I decided to create a portfolio out of them in Google Finance. Now this particular portfolio servers as one of my own personal indicators of how the economy is faring. One of the few.
