Advisor subcommand

Interactive market analysis, portfolio review, and buy recommendations:

investdaytip advisor                          # Interactive mode (asks for risk, region, etc.)
investdaytip advisor --risk moderate          # Non-interactive with risk preset
investdaytip advisor --risk aggressive -r us -a stocks    # US stocks, aggressive, non-interactive
investdaytip advisor --risk moderate --portfolio portfolios/portfolio.txt  # Custom portfolio

See investdaytip advisor --help for all options.

OpenCode AI Agent (chat mode)

Instead of memorizing flags, talk to an AI investment advisor that understands your portfolio, checks market fear, and suggests buys — powered by OpenCode.

Usage

Once configured, invoke the advisor from the project root:

@advisor  what's the market pulse?

The agent will greet you, present options, and never run analysis without your confirmation. Full conversational flow:

1. You: @advisor
2. Agent: "What would you like? Market pulse / Portfolio review / Buy recs / Full analysis?"
3. You: "Market pulse, moderate risk"
4. Agent: Runs VIX/VXN check, bubble risk, bubble burst signals → presents results

See the agent definition for full details on capabilities and interpretation.

Options

Flag	Description	Default
--risk {conservative,moderate,aggressive}	Risk profile (if omitted, asked interactively)	interactive
--portfolio PATH	Path to portfolio ticker file	portfolios/portfolio.txt
-a, --asset-class {all,stocks,etfs}	Asset class filter for buy recommendations	interactive
-r, --region {all,us,eu,asia}	Region filter for buy recommendations	interactive
-c, --currency {all,USD,EUR,GBP,…}	Currency filter	interactive

HTML export

Generate an interactive report that works offline (single file with inline CSS/JS):

investdaytip -n 25 -a all -r all --export-html investdaytip-report.html

The generated report includes filters for:

• Text search (ticker/name/sector)
• Asset class (stock / etf)
• Region (us / eu / asia)
• Minimum score
• Minimum 1M return (%)
• Minimum 1Y return (%)

It also includes:

• Click-to-sort columns (ascending/descending)
• Full-width responsive layout (uses available browser width)
• Pre-rendered rows + client-side interactivity (works even if JS is restricted)
• Direct platform links in table columns: Ticker (Google Finance), T (TradingView), Y (Yahoo Finance)

Google Finance exact links

The Ticker column uses exact Google Finance quote URLs when a ticker suffix is recognized (format: https://www.google.com/finance/quote/SYMBOL:EXCHANGE?hl=en).

Current suffix mapping includes:

• US (no suffix) → NASDAQ by default, with explicit overrides for known symbols (for example HWM → NYSE)
• Germany .DE → ETR, .F → FRA
• France .PA → EPA
• Netherlands .AS → AMS
• UK .L → LON
• Spain .MC → BME
• Italy .MI → BIT
• Switzerland .SW → SWX
• Sweden .ST → STO
• Denmark .CO → CPH
• Finland .HE → HEL
• Norway .OL → OSL
• Japan .T → TYO
• Hong Kong .HK → HKG
• Singapore .SI → SGX
• India .NS → NSE
• South Korea .KS → KRX
• Taiwan .TW → TPE
• Australia .AX → ASX
• Canada .TO → TSE
• China .SS → SHA, .SZ → SHE

When a suffix is not mapped, the report falls back to Google Finance search URL.

TradingView links use the same exchange mapping logic.

Programmatic API

from investdaytip import get_recommendations

# Get top 5 Asian stocks
picks = get_recommendations(top_n=5, region="asia", asset_class="stocks")
for s in picks:
    print(f"{s.data.ticker} ({s.asset_type}) — score={s.total:.1f}")
    print(f"  Price: {s.data.current_price} {s.data.currency}")
    print(f"  1M: {s.data.return_1m:.2%}  1Y: {s.data.return_12m:.2%}")
    print(f"  Why: {'; '.join(s.rationale[:3])}")

# Or mix regions and asset classes
picks = get_recommendations(top_n=10, region="all")  # US + EU + Asia stocks & ETFs

---

Output

Each recommendation includes:

Column	Meaning
Type	STOCK or ETF
Ticker / Name / Sector	Identification
Ticker link	Opens Google Finance in a new tab
T / Y	Opens TradingView / Yahoo Finance in a new tab
Price	Current price in native currency
P/E	Trailing price-to-earnings ratio (stocks; - when unavailable)
1M Δ	% change vs ~22 trading days ago
1Y Δ	% change vs ~252 trading days ago
Score	Composite 0-100 weighted score
Breakdown	Four sub-scores (shown in a compact single line)
Why	Top 3 rationale notes

---

Scoring Model

Each metric is normalized to 0-100 via piecewise-linear functions over empirically reasonable ranges. Missing data contributes a neutral 50 so a ticker isn't penalized for lacking a metric.

Stocks (Graham/Buffett + Momentum)

Pillar	Weight	Metrics
Quality	35%	ROE, profit margin, earnings & revenue growth
Value	25%	trailing P/E, P/B, PEG
Health	20%	Debt/Equity, current ratio, free cash flow
Trend	20%	price vs SMA200, 12-month return, SMA200 slope

ETFs

Pillar	Weight	Metrics
Returns	40%	3y avg, 5y avg, 12m return
RiskAdj	25%	Sharpe proxy (r12 - rf) / σ, annualized volatility
Size	15%	AUM (log scale)
Cost/Yield	20%	expense ratio (lower=better), dividend yield

---

Universes

When no -t is given, InvestDayTip uses curated universes:

• US stocks — 58 large-caps across all S&P sectors (src/investdaytip/universe.py)
• US ETFs — 41 broad-market, factor, sector and bond ETFs (etf_universe.py)
• EU stocks — 65 large-caps from DAX, CAC, FTSE 100, IBEX, AEX, SMI, FTSE MIB, Nordics (eu_universe.py)
• EU UCITS ETFs — 38 broad, sector and bond UCITS ETFs (eu_etf_universe.py)
• Asia stocks — 76 large-caps from Japan, Hong Kong, Singapore, India, South Korea, Taiwan, and Australia (asia_universe.py)
• Asia ETFs — 24 broad-market, country-specific, and sector ETFs with significant Asian exposure (asia_etf_universe.py)

Tickers use Yahoo Finance suffixes:

• US: no suffix (AAPL, MSFT)
• EU: .DE Xetra · .PA Paris · .AS Amsterdam · .L London · .MC Madrid · .MI Milan · .SW Swiss
• Asia: .T Tokyo · .HK Hong Kong · .SI Singapore · .NS NSE India · .KS Korea · .TW Taiwan · .AX Australia

Limitations & Caveats

• No currency normalization — prices, market caps and AUM stay in native currency
• Currency filter (-c) compares against yfinance's reported currency field; tickers with a missing/unknown currency pass only when -c all
• min_market_cap filter (--min-market-cap) is applied against raw native-currency figures
• Some European tickers change Yahoo symbols over time; if a ticker is delisted in Yahoo it's silently skipped
• ETF expense ratios are sometimes missing in yfinance — the scorer falls back to a slightly optimistic default (60) in that case
• Long-term, fundamental-driven model: not suitable for short-term/day trading signals
