review — Portfolio Review
Every number comes from Bloom's financial data. Not a language model's training data.
Trigger: /review <HOLDINGS> — when a user shares their portfolio holdings.
Holdings can be:
- Tickers + percentages:
AAPL 40%, MSFT 30%, GOOGL 30%
- Tickers + dollar amounts:
AAPL $10000, MSFT $7500, TSLA $2500
- Just tickers (assume equal weight):
AAPL MSFT GOOGL NVDA

mkdir -p /tmp/bloom
Steps (Run in Order)
1. Parse holdings into JSON
Convert whatever format the user gave into a JSON object with ticker:weight pairs summing to 1.0.
Examples:
AAPL 40%, MSFT 30%, GOOGL 30% → {"AAPL": 0.4, "MSFT": 0.3, "GOOGL": 0.3}AAPL $10k, MSFT $5k, TSLA $5k → {"AAPL": 0.5, "MSFT": 0.25, "TSLA": 0.25}AAPL MSFT GOOGL NVDA → {"AAPL": 0.25, "MSFT": 0.25, "GOOGL": 0.25, "NVDA": 0.25}
2. Portfolio-level analysis
bloom portfolio '{"AAPL": 0.4, "MSFT": 0.3, "GOOGL": 0.3}' -o /tmp/bloom/review-portfolio.json
3. Stock info (batch — up to 10 tickers at once)
bloom info AAPL MSFT GOOGL -o /tmp/bloom/review-info.json
4. Revenue growth financials per ticker
bloom financials AAPL --type revenue_growth -o /tmp/bloom/review-fin-AAPL.json
bloom financials MSFT --type revenue_growth -o /tmp/bloom/review-fin-MSFT.json
5. Extract key fields
cat /tmp/bloom/review-portfolio.json | jq '{grade, concentration_risk, sector_breakdown, correlation, suggestions}'
cat /tmp/bloom/review-info.json | jq '.[] | {ticker: .symbol, pe: .pe_ratio, sector: .sector, analyst: .analyst_consensus, market_cap: .market_cap}'
cat /tmp/bloom/review-fin-AAPL.json | jq '.[-4:]'
cat /tmp/bloom/review-fin-MSFT.json | jq '.[-4:]'

| D | Expensive (35-50) |
| F | Extreme premium (50+ avg P/E) |
Growth
| Grade | Criteria |
|---|
| A | Avg revenue growth >20% YoY across holdings |
| B | 12-20% avg growth |
| C | 5-12% avg growth |

| F | Declining revenue across majority of holdings |
Risk
| Grade | Criteria |
|---|
| A | Low correlation between holdings, defensives present |

Output Format
## Portfolio Review — Overall Grade: [A/B/C/D/F]
### Top 3 Problems
1. 🔴 [Biggest issue — be specific. "65% in tech" not "concentration risk"]
2. 🟡 [Second issue]
3. 🟡 [Third issue — can be 🟢 if portfolio is solid]
### Holdings Breakdown
| Ticker | Weight | P/E | Revenue Growth | Analyst | Flag |
|--------|--------|-----|----------------|---------|------|
| [TICKER] | [X]% | [X] | [+X%] | [Buy/Hold/Sell] | [⚠️ if issue] |
### Sector Exposure
| Sector | Weight |
|--------|--------|
| Technology | X% |
| Healthcare | X% |
| [etc.] | |
[One sentence: is sector concentration a problem here?]
### Risk Assessment
**Concentration:** [Single stock or sector risk]
**Correlation:** [How much do these move together?]
**Drawdown risk:** [What happens if tech sells off 30%? If rates rise?]
### Suggestions
1. [Specific and actionable — "Add VTI or an international ETF to reduce single-stock risk"]
2. [Second suggestion]
3. [Third suggestion]
*Keep suggestions realistic. Don't tell someone to add 15 new positions.*
### Grade Breakdown
| Category | Grade | Why |
|----------|-------|-----|
| Diversification | [X] | [One-line reason] |
| Valuation | [X] | [One-line reason] |
| Growth | [X] | [One-line reason] |
| Risk | [X] | [One-line reason] |

Notes
- Be honest about problems. A portfolio of 3 high-P/E tech stocks is a C at best — say so.
- Suggestions should be specific, not "consider diversifying." Say what to buy or trim.
- If a user has fewer than 5 holdings, the diversification grade is almost always C or below.
- Don't penalize concentrated portfolios held by people who clearly know what they're doing (e.g., single-stock employee RSUs situation) — acknowledge the context if they share it.
