Those include the Schwab U.S. Large-Cap Growth ETF (NYSEArca:SCHG), the Schwab U.S. Large-Cap Value ETF (NYSEArca:SCHV) and the Schwab U.S. Small-Cap ETF (NYSEArca:SCHA). Charles Schwab, the discount broker that entered the exchange-traded fund market less than six months ago, filed with the Securities and Exchange Commission today to offer three U.S. Treasury ETFs, including one designed to protect investors from the ravages of inflation. The index includes all publicly issued U.S. Treasury inflation-protected securities that have at least one year remaining to maturity, are rated investment grade and have $250 million or more of outstanding face value.
