Using Marine Traffic (AIS) to make stock picks?
You can. Speculating on marine traffic is more closely tied to oil trades and ocean shipping container rates, than trades on any particular companies. But companies heavily tied to ocean shipping can be ripe for speculation. The baltic dry index is created for this analytical purpose, and that information can be used as an indicator to hedge or speculate in container freight swap agreements.  The Guggenheim Shipping Exchange Traded Fund also serves as a proxy for maritime shipping profitability, but it is just a bundle of several publicly traded marine shipping companies shares.
