Compare 2–5 stocks head to head on one table — business quality, growth, valuation, balance sheet, momentum, risks and catalysts — then argue the pick: which one, why, what would flip it, and whether owning more than one adds anything.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Head-to-Head Compare

## ⚠️ Data Verification — Do This Before Any Analysis

Before running any analysis, always retrieve the latest market data for the ticker:

1. **Fetch current price** — use web search or ask the user for the live price, 52-week range, and market cap. Never assume a price from training data.
2. **Confirm key figures** — for **every** ticker, on the **same as-of date**: price, enterprise value (market cap + debt + leases − cash), TTM revenue, EBIT, free cash flow and stock-based compensation, invested capital for ROIC, net debt and interest expense, 3-year revenue history, NTM consensus revenue and EPS, and the last guidance change. Note each company's fiscal year-end and calendarize to a common trailing-twelve-month window — comparing one company's March year with another's December year is comparing two different economies. A comparison in which one ticker's figures are a quarter staler than the others' is biased toward whichever side the missing quarter favours.
3. **State your data source** — fill in the `Data & Sources` header (next section) so the origin, as-of date, retrieval path, and confidence of every figure are explicit at the top of the output.

How to install

The exact contents, by fingerprint

mdr add yennanliu/investskill/compare@sha256:f5d12549395a3e19

The line at the top of this page pins the label git:20261024.1726f29, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
