BLUFStocks rally to end volatile week as yields, oil swing markets

· Sent · By Reveille Brief Team

U.S. and international stocks rose on Friday, closing out a bumpy week driven by surging Treasury yields and falling oil prices. The S&P 500 and Dow both gained, while Treasury yields hit their highest levels since the financial crisis before markets shrugged off the pressure late in the week.

TSP 101

The G Fund's principal and interest payments are guaranteed by the U.S. government, a protection unique among the TSP funds. Because it isn't traded on the open market like stocks or bonds, it doesn't experience the daily price swings seen in the F, C, S, and I Funds.
