Thrift Savings Plan (TSP) fund performances surged for a second year in a row in 2024, as investors dropped hundreds of billions of dollars into the market, reported Fed Smith.
The C fund, which performed a personal best of 26.25% in 2023, saw a positive return of 24.96% in 2024. The S fund came in at 16.93% in 2024, while the I fund saw a 4.27% return and the G fund had a 4.40% positive return.
Fed Smith attributes the growth to rising market activity. In 2024, the S&P 500 went up 23% and recorded 57 highs throughout the year, likely due to the increased movement surrounding artificial intelligence (AI) technology.
The emergence of high-tech tools and products has historically helped with increasing stock performances. U.S. stocks had their two best consecutive years in 1997 and 1998, right when the dot-com boom ballooned to serious market capitalizations and rapid startup growth.
Fed Smith also links inflation to influencing stock market returns in 2024. The rate of inflation went down from 9% in mid-2022 to 2.6% in October 2024, therefore ensuing a resilient stock market.
As the stock market grew, TSP investors poured hundreds of billions to the two largest stock funds: the C fund and S fund. Total assets in these funds increased from $274.4 billion to $460.8 billion by the end of December 2022, while G fund assets fell from $240.1 billion to $229.1 billion in the same timeframe.
