John Boozman, the senior United States senator from Arkansas, disclosed several trades he made in June and July as he continues to actively participate in the stock market.

The biggest trade Boozman made in July is the selling of Goldman Sachs Access Treasury 0-1 Year ETF (GBIL:US). This Fund seeks to provide investment results that closely correspond, before fees and expenses, to the performance of the FTSE US Treasury 0-1 Year Composite Select Index, according to Goldman Sachs.

Boozman sold between $15,000 and $50,000 worth of shares of GBIL on July 27 when the stock price closed at $99.84.

Elsewhere, the Senator from Arkansas also sold shares of the iShares 3-7 Year Treasury Bond ETF (IEI:US), which seeks to track the investment results of an index composed of U.S. Treasury bonds with remaining maturities between three and seven years.

The Senator also disclosed he invested between $1,000 and $15,000 in the iShares 20+ Year Treasury Bond ETF (TLT:US) and the iShares 10-20 Year Treasury Bond ETF (TLH:US).

These four trades come after Boozman made over 15 trades in June, mostly selling ETFs. The biggest trade in June includes selling between $15,000 and $50,000 worth of shares of the FlexShares STOXX Global Broad Infrastructure Index Fund (NFRA:US) on June 14.
