Lao Luo Cross-Market Sub-One PB Value Screener

Problem

Low PB is not the same as undervalued. Across A-share, HK, and US markets, many sub-one PB stocks can be cyclical lows, but they can also come from inflated assets, weak cash flow, or broken business models. Listing candidates by PB < 1 alone easily mixes value traps into the watchlist.

How It Works

The skill evaluates candidates from the perspective of a 1x PB industrial investor: it first captures the current system time, then scans markets by their valuation context, keeping 5–15 candidates per market before narrowing to 3–8 priorities. Core checks include:

• Valuation screen: PB below 1, with attention to deeper discounts.
• Earnings quality: 5–10 year average ROE above 8%.
• Cash validation: operating cash flow / net income near or above 1 over time.
• Asset reality: goodwill, intangibles, receivables, and inventory that may erode net assets.
• Global comparison: PB-ROE positioning against 2–4 peers.

It then outputs a watchlist, classifying names as deep value, cyclical bottom, high-yield, or observe/trap, and generates an HTML report suitable for email delivery to the configured address.

Boundaries

It is suited to cross-market sub-one PB screening and research framing, not full stock due diligence. PB means different things for banks, insurers, and real estate, so capital structure and regulatory context matter. Missing history should lower confidence instead of being filled in.
