THE SENTINEL PLAN
ETF Building Blocks
Simple, transparent and diversified instruments for disciplined long-term allocation.
ETFs are one of the core implementation tools of the Sentinel Plan. They allow investors to access diversified baskets of bonds, equities or money-market instruments through a single exchange-traded product. In Sentinel, ETFs are not used for speculation. They are used to simplify portfolio construction, reduce unnecessary costs, improve diversification and keep the investment strategy transparent.

ETF Bulding Block
The stabilising bond foundation of a balanced portfolio.
A core bond fund is a diversified mix of high-quality bonds designed to provide stability, regular income and portfolio balance. Instead of buying one bond, the fund spreads exposure across several bond sectors.

ETF Fundamentals
A simple framework to understand how ETFs work, what investors own, and why they are useful for portfolio construction.
In our strategy pages, ETFs are treated as implementation tools: they help translate a macro view into diversified, transparent and disciplined portfolio exposure.

The Analogy
Think of an ETF as a basket. Instead of buying one bond, one stock, or one cash instrument, an ETF allows investors to access a diversified group of assets through a single exchange-traded product.
For example, one bond ETF may hold hundreds of bonds. One equity ETF may hold hundreds of companies. This makes ETFs useful for building diversified portfolios without selecting every individual security manually.
Market Insight
ETFs are useful because they combine diversification, transparency, daily liquidity and cost efficiency. Investors can use them to express a precise portfolio role: cash management, short-duration bonds, core bonds, equity exposure, inflation protection or sector allocation.
But an ETF is not automatically safe. Its risk depends on what it owns.
Key Vocabulary
- • Index: the benchmark the ETF tries to follow.
• Holdings: the assets inside the ETF.
• TER: the annual cost charged by the fund.
• Liquidity: how easily the ETF can be bought or sold.
• Replication: whether the ETF holds assets directly or uses swaps.
• Distribution: whether income is paid out or reinvested.
Why ETF Prices Move
ETF risk comes from the assets inside the basket.
ETFs are implementation tools. They allow investors to access a diversified basket of assets through one traded product. But an ETF is not automatically defensive or aggressive. A money-market ETF, a short-duration bond ETF, a global equity ETF and a high-yield bond ETF can all behave very differently because they hold different assets.
The basket rule
The ETF price reflects the value of the underlying holdings. If the bonds, equities or cash instruments inside the fund change in value, the ETF price usually changes with them.
The risk rule
ETF risk depends on duration, credit quality, equity exposure, currency exposure and liquidity. The label ‘ETF’ only describes the structure, not the risk level.

ETFs are not automatically
safe
An ETF is not a risk level. It is a structure. A government bond ETF, a global equity ETF and a leveraged technology ETF are all ETFs, but they do not carry the same risk. The Sentinel Plan classifies ETFs by what they hold, not by the ETF label itself.

Sentinel ETF Selection Checklist
How ETFs generate
returns
Equity ETF Return = Earnings Growth + Dividends + Valuation Change − Costs
Bond ETF Return = Yield Income + Price Change (Rates) + Credit Spread Change − Costs
ETF SELECTION QUESTIONS
- What index does the ETF track?
- What assets are inside?
- What is the total cost?
- Is it UCITS-compliant?
- Is it physically or synthetically replicated?
- Is it accumulating or distributing?
- What is the duration?
- What is the credit quality?
- Is currency hedged?
- Is it liquid?
- Does it fit Sentinel’s defensive objective?
The Sentinel Plan uses ETFs as institutional building blocks. The objective is to create diversified exposure with clear costs, transparent holdings and controlled risk. ETFs are not selected because they are popular, but because they allow the portfolio to express a precise role: liquidity, defensive income, inflation protection, broad bond exposure, or limited long-term growth.
