The seeming lockstep price of Crude Oil and the Morgan Stanley Capital International EAFE based TSP 401k.
A friend of mine at work got into the I fund (based on the Morgan Stanley Capital International EAFE) at the right time and rode it to some great profits. He said that as oil prices rose so did the I fund. Being a curious fellow I decided to take a look and an interesting pattern appeared.
I graphed the five funds available in the Thrift Savings Plan, 401k retirement plan.
