Programmatic stock research

Compare the businesses—not just the tickers.

4,949 canonical, same-sector comparisons built from 460 public-company profiles and a refreshed SEC filing snapshot. Every pair shares either an SEC industry or a specific maintained research theme, then contrasts the actual businesses, fiscal calendars, risks, and primary filings.

Food, beverages, household goods, and tobacco — the classic defensive sector where pricing power meets inelastic demand.

Energy comparisons

1,498

Banks, insurers, asset managers, and exchanges — the plumbing of capital markets, geared directly to interest rates and credit.

152

Pharmaceuticals, biotech, medical devices, and managed care — defensive demand paired with binary drug and regulatory catalysts.

Semiconductors, software, and hardware — the companies building the digital and AI infrastructure the rest of the economy runs on.

REITs across offices, data centers, industrial, and residential — the most rate-sensitive corner of the equity market.

Regulated power and water — bond-like income proxies whose relevance is being reshaped by data-center and electrification demand.

How the comparison universe is built

Companies are compared only with peers in the same market sector. This prevents meaningless combinations created merely to inflate a page count.

A pair must share an SEC industry classification or a specific maintained research theme such as artificial intelligence, rates, tariffs, or international markets. A generic “US markets” label is deliberately not enough.

A pair qualifies for indexing only when both companies have a substantive profile and a primary annual filing in the SEC snapshot.

A comparison is the setup. The thesis is the call.

this pair shows how the businesses differ. Membership is the monthly sourced view of who could benefit, what could break, and what evidence matters next. $15/month or $150/year.
