This ETF invests mainly in Treasury Inflation-Protected Securities (TIPS) issued by the US government, offering a means of hedging against inflation. Rather than simply tracking an index, it relies on Dimensional's active management to select securities with higher expected returns and build the portfolio.

It suits long-term investors who want to protect against the erosion of cash value caused by rising prices and maintain the real purchasing power of their portfolios.

It is an actively managed ETF launched by Dimensional in 2021.

The fund analyzes term premiums and expected inflation across TIPS of various maturities and adjusts its weightings accordingly. It generally selects and holds medium- to long-term inflation-linked bonds with maturities of 5 to 20 years, and it manages duration flexibly in line with market conditions to strengthen its inflation defense.

• Active TIPS management applying Dimensional's factor model
• Active portfolio adjustments in response to changes in inflation expectations

Assets under management (AUM) stand at $1.1B, and the total expense ratio is 0.11% per year.

While keeping fees lower than TIP, a passive TIPS ETF, it seeks to deliver better performance than the market through professional active management.

Returns have shown volatility depending on shifts in inflation figures and the Federal Reserve's interest rate stance, but the fund has delivered results as an inflation hedge during periods of rising real yields.

Money seeking asset protection has been flowing in while inflationary pressure persists, and conservative capital looking for stable income and preservation of asset value continues to arrive steadily.

It is an efficient tool for preserving asset value during inflationary periods, but it carries the risk of bond price declines when market interest rates surge.

TIP, shown in the table, is the market-standard passive TIPS ETF, while VTIP and STIP are alternatives that focus on short-term inflation-linked bonds to reduce interest rate sensitivity. Investors seeking a more aggressive inflation defense may also consider LTPZ, which invests in long-term inflation-linked bonds, and those who prioritize competitive fees may want to compare SCHP as well.

DFIP follows a strategy concentrated in a specialized bond asset linked to inflation, so before making an investment decision, use the key checklist below to carefully verify its inflation defense effect and the impact of real yields.

TIPS react more sensitively to real yields than to nominal yields. Investors should understand that even when inflation occurs, bond prices can fall if real yields rise by more.

It is a strong option for investors who want to protect the real purchasing power of their assets over the long term. It is a core holding that offers access to Dimensional's professional bond management strategy at a low cost.
