The lone exception was the government securities (G) fund, which gained 0.18 percent last month. The fund -- one of the most stable TSP offerings -- has earned 1.12 percent so far this year.
Fixed income bonds lost the least ground of the other four basic funds in August, ending the month down 0.48 percent. The F Fund has lost 2.62 percent for 2012.
