Overview

The FlexShares iBoxx 3-Year Target Duration TIPS Index Fund, trading under the ticker TDTT, operates within the US Bonds - TIPS category managed by Flexshares Trust. This fund holds an asset base of $2.56 billion and is currently priced at $23.66 per share. It carries an expense ratio of 0.18% and offers a dividend yield of 4.57%. In terms of overall standing, the ETF ranks #376 out of 458 tracked funds across all categories, receiving an ETFValuer grade of C with a score of 51.1/100. Within its specific category of 6 ETFs, the fund sits in the middle of the pack regarding its overall ranking. The combination of a substantial asset under management and a moderate expense ratio suggests a level of investor adoption consistent with a mid-tier option in the TIPS sector.

Short-term performance shows mixed results, with the fund gaining +0.13% over one day before declining -0.17% over the week and -0.08% over the month. The three-month return extended the negative trend to -0.64%, yet the fund recovered to post a +1.09% gain over six months. Year-to-date returns have improved to +1.26%, while the one-year return stands at +2.75%. Longer-term data indicates a significant acceleration in performance, with the three-year return reaching +15.26%. This trajectory illustrates a divergence where recent short-term volatility contrasts with stronger multi-year growth.

The fund is assigned a Very Low volatility label and maintains a beta of 0.33, indicating that its price movements are generally muted relative to broader market fluctuations. Despite this low volatility, the Sharpe ratio is recorded at -1.17, suggesting that the risk-adjusted returns have been negative over the measured period. The maximum drawdown was limited to -1.52%, which aligns with the low volatility and beta figures to show resilience during market dips. This combination of low beta and a small maximum drawdown implies the fund experiences limited downside severity, even though the negative Sharpe ratio indicates that the returns generated have not sufficiently compensated for the risks taken. The data collectively points to a stable asset class that has struggled to generate positive risk-adjusted gains recently.

10-Year Treasury Yield: 4.65% (as of 2026-07-27) — The yield on 10-year US Treasury bonds — the standard "risk-free rate" benchmark used to contextualize this fund’s Sharpe ratio and returns.

CBOE Volatility Index (VIX): 18.67 (as of 2026-07-27) — A real-time gauge of expected S&P 500 volatility over the next 30 days — useful context for this fund’s own volatility label.

10-Year Breakeven Inflation Rate: 2.20% (as of 2026-07-28) — The market’s implied 10-year inflation expectation, derived from Treasury and TIPS yields — directly relevant to this fund’s inflation-protection design.

TDTT Liquidity, Domicile & Tax Treatment

Liquidity: Quoted bid/ask spread is — and average daily volume is 207K/day. Tighter spreads and higher volume mean lower round-trip trading costs; this is a live-market snapshot and can widen during volatile sessions. AUM of $2.56B provides ample scale, supporting tight spreads and issuer commitment to keep the fund open.

Domicile & tax treatment: TDTT is a US-domiciled, SEC-registered ('40 Act) exchange-traded fund. Dividends and capital gains distributions are reported to US investors on Form 1099-DIV, and the fund is not subject to the PFIC reporting or UCITS-specific rules that apply to Irish- or Luxembourg-domiciled funds. Non-US investors should note that US-domiciled ETFs are generally subject to 30% US withholding tax on dividends (unless reduced by treaty) and to US estate tax exposure on the position — Irish-domiciled UCITS ETFs tracking the same index often avoid both, which is why non-US residents frequently prefer the UCITS equivalent where one exists. This is general information, not tax advice — consult a tax professional for your situation.
