What is valuation-calculator?

A stock valuation workflow that compares a company's PE, PB and PS measures with their past levels and with similar companies, then calculates price targets using PE or PB methods.

Use it during stock analysis, when setting a trade target price, or when comparing companies in the same industry.

It gives a structured way to judge whether a stock looks expensive or cheap instead of relying only on its current price.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00092	$0.00895
Opus 5.5	$0.00037	$0.00358
Sonnet 5.5	$0.00018	$0.00179
Haiku 4.5	$0.00009	$0.00089

Security

Grade A, and why

valuation-calculator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Valuation Calculator

Quantitative, relative valuation for investment decisions (PE/PB percentiles + peer comparison + target price). For absolute DCF-style intrinsic value, use the intrinsic-value-analysis skill instead.

When to Use

During stock analysis (the valuation step)
When deciding a target price for a trade
When comparing multiple candidates in the same sector

Prerequisites

Uses the sibling tushare-data / stock-market-data skills. Set once per shell:

export TUSHARE_TOKEN=<your Tushare Pro token>    # never hard-code; see the tushare-data skill
PY=python3                                       # a python3 with tushare/pandas/akshare (e.g. stock-market-data/.venv/bin/python3)
SKILLS=~/.claude/skills                          # where you installed these skills
TS=$SKILLS/tushare-data/scripts/fetch_tushare.py
AK=$SKILLS/stock-market-data/scripts

Methods

1. Historical Percentile

Use Tushare daily_basic for direct PE/PB/PS time series (no manual calculation needed):

# Get 3-year PE/PB/PS history for percentile calculation
$PY $TS --mode daily_basic --symbols {CODE}.SZ --start 20230101

From the returned data:

Calculate PE_TTM percentile over available history
Calculate PB percentile over available history
Identify current position in historical range

2. Peer Comparison

# Tushare: valuation + financial ratios for each peer
$PY $TS --mode daily_basic --symbols {code1}.SZ --start 20260301
$PY $TS --mode fina_indicator --symbols {code1}.SZ
# Repeat for each peer...

# Fallback: AKShare (batch)
$PY $AK/fetch_financial_data.py --mode stock --symbols {code1},{code2},{code3}

Compare: PE, PB, ROE, revenue growth, net margin across peers. Identify: who is cheapest relative to growth? (PEG ratio)

Supplement with WebSearch for analyst consensus (券商一致预期), forecasts, and cross-sector peer comparison data:

WebSearch: "{stock name} 一致预期 估值 目标价"

3. Target Price Derivation

Methods available:

PE-based: Target PE × Expected EPS = Target Price
PB-based: Target PB × Book Value = Target Price
DCF-simplified: skip here; use the intrinsic-value-analysis skill for a proper DCF-style approach

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
