The user wants to express a view on a sector or theme via an ETF. Don't just list options — give a clear ranked recommendation.

**1. DEFINE THE EXPOSURE**
What does owning this sector/theme actually mean?
- What's the macro thesis driving interest in it?
- What kind of companies should an ETF in this space hold?
- What would a bad ETF in this space hold instead?

**2. THE MAIN OPTIONS**
List the 3–5 most relevant ETFs for this sector/theme:

| ETF | Issuer | AUM | Expense Ratio | # Holdings | Index |
|-----|--------|-----|---------------|------------|-------|
| | | | | | |

**3. METHODOLOGY DIFFERENCES**
This is the most important section — ETFs covering the "same" sector can be dramatically different:
- Market-cap weighted vs equal weight vs revenue weighted?
- Broad sector vs narrow sub-theme?
- US-only vs global?
- Pure-play vs mixed exposure?
- What is the largest holding and does it dominate?

**4. WHAT YOU'RE ACTUALLY BETTING ON**
For each ETF, one sentence: if you own this, what has to be true for it to outperform?

**5. RANKED RECOMMENDATION**

**#1 [TICKER] — Best overall for most investors**
Why: cost, liquidity, clean exposure to the thesis

**#2 [TICKER] — Best for [specific use case]**
Why: higher conviction / purer play / different factor tilt

**#3 [TICKER] — Only if [condition]**
Why: niche use case, higher cost justified by specificity

**6. WHAT TO AVOID AND WHY**
Name any ETFs in this space that look relevant but have hidden problems: excessive concentration, high fees, poor liquidity, methodology that drifts from the stated theme.

**7. THE HONEST CAVEAT**
Is this sector ETF actually the right instrument for the thesis, or would a basket of individual stocks give cleaner exposure? When does the sector ETF work against you (e.g. owning XLE for oil but getting dragged by refiner holdings that move differently)?
