# Equity-Factor Sleeve (B2) — Implementation Plan
> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
**Goal:** A cross-sectional multi-factor (value+quality+momentum) US-equity book on a dynamic top-N-by-dollar-volume universe, built as three construction variants (long-only / long-short / long-tilt), each a `ForwardStrategy` paper-forward track the cockpit ingests.
**Architecture:** Pure factor math in `domain/strategies/equity_factor.py`; Tiingo fundamentals + universe behind new ports/adapters (reusing `TiingoDailyClient` for prices); three live-booking `ForwardStrategy` services sharing one factor-target builder; three Dagster assets feeding the existing `cockpit_forward`.
**Tech Stack:** Python 3.13, numpy, urllib (Tiingo), Dagster 1.12.x, pytest, strict mypy.
**Spec:** `docs/superpowers/specs/2026-06-16-equity-factor-sleeve-design.md`
**Conventions (same as B1):** tests `cd ~/Work/fxhnt && .venv/bin/python -m pytest <path> -v`; type-check `.venv/bin/python -m mypy src/fxhnt`. Orchestration modules MUST NOT use `from __future__ import annotations`; every other new module SHOULD. Use `dict[str, Any]` to match the `ForwardStrategy` Protocol. Commit per task with trailer `Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>`. No live network in tests (fake the clients / monkeypatch `_get`). Tiingo key via `os.environ["TIINGO_API_KEY"]`, header `Authorization: Token <key>`, NEVER printed.

## Task 1: Ports — FundamentalsClient + UniverseSource
**Files:** Modify `src/fxhnt/ports/market_data.py`.
- [ ] **Step 1: Append the ports** (no test — exercised by later fakes):
```python
class FundamentalsClient(Protocol):
def metrics(self, symbol: str) -> dict[str, float]:
"""Latest daily valuation metrics: {'peRatio','pbRatio','marketCap', ...} (most recent available)."""
...
def statement_metrics(self, symbol: str) -> dict[str, float]:
"""Latest reported statement metrics: {'piotroskiFScore','roe','debtEquity','grossMargin', ...}."""
...
class UniverseSource(Protocol):
def top_n(self, n: int) -> list[str]:
"""The n most-liquid US common-stock tickers by trailing dollar-volume (descending)."""
...

## Task 3: TiingoFundamentalsClient
**Files:** Create `src/fxhnt/adapters/data/tiingo_fundamentals.py`; Test `tests/integration/test_tiingo_fundamentals.py`.
**Endpoints (verified live):** `GET {base}/tiingo/fundamentals/{ticker}/daily?startDate=...` → list of `{date, peRatio, pbRatio, marketCap, enterpriseVal, trailingPEG1Y}` (use the most recent). `GET {base}/tiingo/fundamentals/{ticker}/statements?startDate=...` → list of statement objects; the relevant metrics (`piotroskiFScore, roe, debtEquity, grossMargin, profitMargin, revenueQoQ`) appear in the statement data — the implementer must inspect one live response (header-auth, NEVER print the key) to confirm the exact nesting and map it; tests use fixtures of that shape.
- [ ] **Step 1: Write failing tests** — a `FakeFundamentals`-free direct test: monkeypatch the client's `_get` to return fixed daily + statement fixtures; assert `metrics("AAPL")` returns the latest `{peRatio, pbRatio, marketCap}` and `statement_metrics("AAPL")` returns `{piotroskiFScore, roe, debtEquity, grossMargin}` from the latest statement. (Write the fixtures to match the live shape you confirm in Step 3.)
- [ ] **Step 2: Run → FAIL.**
- [ ] **Step 3: Implement** `TiingoFundamentalsClient(api_key=None, base_url="https://api.tiingo.com")`: `_get` retry helper with `Authorization: Token <key>` header (mirror `tiingo_daily.py`), `metrics()` hits `/daily` (latest row), `statement_metrics()` hits `/statements` (latest, mapping the confirmed field locations). Key from `os.environ["TIINGO_API_KEY"]`, never logged. First run one live call to confirm the statements shape, then code to it.
- [ ] **Step 4: Run → PASS.** mypy clean.
- [ ] **Step 5: Commit** `feat(b2): TiingoFundamentalsClient (daily metrics + statements)`.
---
## Task 4: TiingoUniverseSource
**Files:** Create `src/fxhnt/adapters/data/tiingo_universe.py`; Test `tests/integration/test_tiingo_universe.py`.
**Approach:** Tiingo publishes `https://apimedia.tiingo.com/docs/tiingo/daily/supported_tickers.zip` (CSV: ticker, exchange, assetType, priceCurrency, startDate, endDate). Filter `assetType == "Stock"`, US exchanges (`NYSE,NASDAQ,NYSE ARCA,AMEX`), `priceCurrency == "USD"`, active (endDate recent). From that candidate set, rank by trailing ~30d dollar-volume (close×volume from `TiingoDailyClient`, summed) and return the top-N. To bound cost, cap the candidate set the volume-rank pulls EOD for (e.g. take a large pre-set of liquid names, or sample) — document whatever cap is chosen with a `log`/comment (no silent truncation).
- [ ] **Step 1: Write failing test** — monkeypatch the supported-tickers fetch + the per-ticker volume lookup with fixtures; assert filtering (non-Stock/non-US/inactive dropped) and that `top_n(3)` returns the 3 highest dollar-volume tickers in order.
- [ ] **Step 2: Run → FAIL.**
- [ ] **Step 3: Implement** `TiingoUniverseSource(daily_client, api_key=None)`: fetch+cache the supported-tickers CSV (parse from the zip), filter, compute dollar-volume per candidate over the last ~30 days via `daily_client.adj_closes` (or raw close×volume — note: `adj_closes` returns total-return closes; for dollar-volume use a raw close×volume call or approximate with adjClose×volume — acceptable for ranking), return top-N. Make the candidate cap explicit + logged.
- [ ] **Step 4: Run → PASS.** mypy clean.
- [ ] **Step 5: Commit** `feat(b2): TiingoUniverseSource (supported-tickers + dollar-volume top-N)`.

## Task 5: Factor-target builder + 3 ForwardStrategy services
**Files:** Create `src/fxhnt/application/equity_factor_strategy.py`; Test `tests/integration/test_equity_factor_strategy.py`.
The three services share `_factor_targets(universe, fundamentals, prices) -> dict[str,float]`: pull the universe, fetch each name's metrics+statements+12-1 momentum (from prices), compute family scores → composite → `construction_weights(scores, construction)``{sym: weight}`. Each service is a live-booking `ForwardStrategy` (like `FundingCarryStrategy`): monthly rebalance, daily mark.
- [ ] **Step 1: Write failing test** — fakes for `UniverseSource`, `FundamentalsClient`, `DailyBarClient` returning a small deterministic cross-section (≥6 names with known pe/pb/piotroski/roe/momentum). For each construction (`long`/`ls`/`tilt`): drive the service through two `ForwardTracker` steps (first run freezes; advance the fake prices + cross a month boundary; second run books one row). Assert: the booked return equals the hand-computed `book_return` of the prior targets; `extra` carries `positions` + `last_rebal`; round-trip via `ForwardStateReader` (days-list). Assert `ls` nets ~0 gross 2 in its targets; `long`/`tilt` long-only.
```python
class FakeUniverse:
def __init__(self, tickers): self._t = tickers
def top_n(self, n): return self._t[:n]
class FakeFundamentals:
def __init__(self, m, s): self._m, self._s = m, s
def metrics(self, sym): return self._m[sym]
def statement_metrics(self, sym): return self._s[sym]
# FakeDailyBars from test_paper_strategies (adj_closes) — reuse the same shape.
```
- [ ] **Step 2: Run → FAIL.**
- [ ] **Step 3: Implement** `equity_factor_strategy.py`:
- `_momentum_12_1(closes: dict[str,float]) -> float | None`: 12-1 month return from a date-keyed close series (return over [t-252, t-21], skip last ~21d), None if insufficient history.
- `_factor_targets(universe, fund, bars, construction, n) -> dict[str,float]`: build the cross-section arrays (aligned ticker order), call domain `value_score/quality_score/momentum_score/composite/construction_weights`, return `{sym: w}` for nonzero weights.
- `class _EquityFactorStrategy` with `__init__(self, construction, universe, fund, bars, n=300, borrow_annual=0.01, clock=_today_iso)`; `advance(last_date, extra)`: read `positions`/`last_rebal` from extra; fetch current prices for held (rebalance ? new targets); compute today's `book_return(prev_positions, prev_prices, cur_prices, borrow_daily=borrow_annual/252)`; if first run or month changed → recompute targets via `_factor_targets`; return `([(self._clock(), r)], {"positions":..., "prices":..., "last_rebal":...})`.
- Three thin public classes: `EquityFactorLong`, `EquityFactorLS`, `EquityFactorTilt` wiring `construction="long"/"ls"/"tilt"` (and borrow only for ls).
- [ ] **Step 4: Run → PASS** (+ full suite). mypy clean.
- [ ] **Step 5: Commit** `feat(b2): equity-factor target builder + 3 ForwardStrategy services`.
---
## Task 6: Registry + orchestration
**Files:** Modify `src/fxhnt/registry.py`, `adapters/orchestration/assets.py`, `definitions.py`; Test extend `tests/integration/test_orchestration_definitions.py`.
- [ ] **Step 1: Write failing test** — assert the Definitions asset keys include `eqfactor_long_nav, eqfactor_ls_nav, eqfactor_tilt_nav` and `cockpit_forward` deps include them.
- [ ] **Step 2: Run → FAIL.**
- [ ] **Step 3: Implement**
- `registry.py`: 3 entries with `state_file` `eqfactor_long_state` / `eqfactor_ls_state` / `eqfactor_tilt_state`, display names, sleeve `"equity-factor"`, venue `"us-equity"`, `gate_spec={"min_days":60,"min_total_return":0.0,"min_sharpe":0.3}`.
- `assets.py`: 3 `@asset`s (`eqfactor_long_nav` etc.) following the B1 paper-asset shape via `_run_paper_tracker`, building each service from `TiingoUniverseSource(TiingoDailyClient())`, `TiingoFundamentalsClient()`, `TiingoDailyClient()`. Add all 3 to `cockpit_forward` `deps`.
- `definitions.py`: add the 3 assets to `Definitions(assets=...)` + the job `selection`.
- [ ] **Step 4: Run → PASS** (+ full suite + the definitions count is now 13). mypy clean.
- [ ] **Step 5: Commit** `feat(b2): wire 3 equity-factor assets into the Dagster graph`.
---
## Task 7: Full gate + deploy + verify
- [ ] **Step 1:** Full suite + mypy: `cd ~/Work/fxhnt && .venv/bin/python -m pytest -q && .venv/bin/python -m mypy src/fxhnt` (all green; no new mypy errors). Commit any fixes.
- [ ] **Step 2:** Merge `feat/equity-factor-sleeve` → master + push.
- [ ] **Step 3:** Build + deploy the cockpit image (Argo `fxhnt-cockpit` at master HEAD); confirm build+deploy Succeeded (no new image deps — torch already in; Tiingo key already wired).
- [ ] **Step 4:** Launch one `combined_book_forward_job` materialization (run-launcher, not exec); poll to SUCCESS.
- [ ] **Step 5:** Verify the cockpit: `SELECT strategy_id, days, gate_status FROM forward_summary` shows the 3 eqfactor strategies present (days=0/WAIT on first run — inception freeze, correct).
- [ ] **Step 6:** Update memory (`project_lifecycle_b0_state` or a B2 note): 3 equity-factor variants live; recommend the 30yr-backtest layer next.
---
## Self-Review
**Spec coverage:** universe top-N (Task 4) ✓; value+quality+momentum composite (Task 2) ✓; 3 constructions (Task 2 weights + Task 5 services) ✓; monthly rebalance + live-booking + borrow cost (Tasks 2,5) ✓; ports/adapters reusing TiingoDailyClient (Tasks 1,3,4) ✓; registry + 3 assets → cockpit_forward (Task 6) ✓; deterministic domain + fake-port tests + round-trip (Tasks 2,5) ✓; deploy/verify (Task 7) ✓. Backtest layer correctly OUT of scope.
**Placeholder scan:** the two adapter tasks (3,4) instruct a one-time live shape-confirm for the statements endpoint + supported-tickers parse rather than guessing the exact nesting — concrete (endpoints given) not vague; everything correctness-critical (domain Task 2) is full literal code with exact expected test values.
**Type consistency:** `construction_weights(scores, construction, quantile)`, `book_return(prev_weights, prev_prices, cur_prices, borrow_daily)`, `robust_z(values, k)`, `composite(value_z, quality_z, momentum_z)` used identically in domain (Task 2) and services (Task 5). State-file basenames in Task 6 match the registry entries. Services emit days-list (no state_reader change — confirmed against B1).

# Equity-Factor Sleeve — Design (B2)
**Status:** design (approved in substance 2026-06-16)
**Predecessor:** B1 (6 paper-track strategies + Tiingo equity data). Reuses the `ForwardStrategy`/`ForwardTracker` port, the cockpit `STRATEGY_REGISTRY` + `cockpit_forward` ingest, and `TiingoDailyClient`.
## Goal
A systematic cross-sectional **multi-factor equity book** on a broad liquid US universe, run as **three construction variants** — long-only, long-short market-neutral, and long-tilt — each a separate `ForwardStrategy` paper-forward track through the existing gate. The point is platform-native: build all three, let the forward-gate + DSR decide which construction holds up out-of-sample. Diversifies the (crypto-heavy) book into a new asset class using data we already pay for (Tiingo fundamentals + 30yr EOD).
## What this is NOT (scope boundary)
- **NOT a backtest** — this is the forward-track sleeve. A 30yr backtest/DSR pre-screen layer over the same factor logic is a **separate increment** (strongly recommended to pair, so candidates are screened before months of blind forward). Out of scope here.
- **NOT live execution** — paper-forward only (no broker orders).
- **NOT analyst/estimate data** — Benzinga (earnings estimates/ratings) is not entitled; we use Tiingo *actuals* + price.
## Data (verified live on our Tiingo Power key)
- **EOD** (`/tiingo/daily/{t}/prices`) — adjusted OHLCV, 30yr; via existing `TiingoDailyClient`.
- **Fundamentals daily** (`/tiingo/fundamentals/{t}/daily`) — `peRatio`, `pbRatio`, `marketCap`, `enterpriseVal`, `trailingPEG1Y`.
- **Fundamentals statements** (`/tiingo/fundamentals/{t}/statements`) — `piotroskiFScore`, `roe`, `roa`, `debtEquity`, `grossMargin`, `profitMargin`, `revenueQoQ`, … (85 fields via `/definitions`).
- **Supported tickers** (Tiingo `supported_tickers.zip`) — the candidate list for the universe screener (assetType=Stock, US exchanges, active).
## Architecture (hexagonal, fits the platform)
```
domain/strategies/equity_factor.py pure: z-scores, composite, quantile/rank weights, book return (no I/O)
ports/market_data.py (extend) FundamentalsClient + UniverseSource Protocols
adapters/data/tiingo_fundamentals.py TiingoFundamentalsClient (daily metrics + statements)
adapters/data/tiingo_universe.py TiingoUniverseSource (supported-tickers → filter → dollar-volume rank → top-N)
application/equity_factor_strategy.py 3 ForwardStrategy services (long / ls / tilt) sharing the universe+factor compute
registry.py (extend) 3 entries: eqfactor_long, eqfactor_ls, eqfactor_tilt
adapters/orchestration/assets.py 3 assets → cockpit_forward deps
```
### Universe screener (`TiingoUniverseSource`)
`top_n(n=300) -> list[str]`: load Tiingo supported-tickers (cache the zip), filter to US common stock + active, rank by trailing ~30d **dollar-volume** (close×volume from EOD over the candidate set), return the top-N. Refreshed at each monthly rebalance. (Default N=300; configurable 100500.) To bound API cost, the volume rank uses a coarse pre-filter (e.g. the exchange-listed common-stock subset) before pulling EOD.
### Factor computation (`domain/strategies/equity_factor.py`, pure)
Per rebalance, for the universe cross-section:
- **Value** = z(peRatio) + z(pbRatio) (cheap = high score; guard non-positive/None).
- **Quality** = z(piotroskiFScore) + z(roe) + z(debtEquity) + z(grossMargin).
- **Momentum** = z(12-1 month price return) (skip most recent month).
- Each raw factor is **winsorized** (e.g. ±3σ) then cross-sectional **z-scored**; missing inputs → neutral 0 for that factor (a name needs ≥2 of 3 families present to be scored).
- **Composite** = equal-weight mean of the three family z-scores.
Pure functions: `zscore(values)`, `winsorize(values, k)`, `composite(value_z, quality_z, momentum_z)`, `quantile_weights(scores, construction)`.
### Three construction variants (the `construction` param)
- **`eqfactor_long`** — top-quintile, equal-weight long, weights sum to 1.0.
- **`eqfactor_ls`** — long top-quintile / short bottom-quintile, equal-weight each leg → market-neutral (Σw=0, gross=2.0). Realized return nets a **borrow cost** on the short leg (default 1%/yr, applied per-day).
- **`eqfactor_tilt`** — long-only budget, rank-weighted overweight/underweight (weights ∝ max(0, rank-centered score), normalized to sum 1.0). No shorts.
### Live-booking ForwardStrategy services
Three services (one per construction) share a common `_factor_targets(as_of)` that calls the universe + fundamentals + price clients and returns target weights via the domain. Each `advance(last_date, extra)` (the live-booking pattern, like funding/poc):
- reads prior `positions` (+ `last_rebal`) from `extra`,
- **marks** the held book to today's prices → daily book return (minus borrow cost on shorts for `ls`),
- **rebalances monthly** (`today.month != last_rebal.month` or first run): recompute targets, update positions,
- returns `([(today_iso, book_return)], updated_extra)`; the `ForwardTracker` books forward-only (inception freeze on first run), emits the days-list state the cockpit ingests.
### Registry + orchestration
Three `STRATEGY_REGISTRY` entries (state_file basenames `eqfactor_long_state` / `eqfactor_ls_state` / `eqfactor_tilt_state`; gate_spec e.g. `min_days=60, min_total_return=0, min_sharpe=0.3`). Three Dagster `@asset`s (no `from __future__ import annotations`) mirroring the B1 paper assets, added to `cockpit_forward` deps + Definitions/job. They fetch live HTTP (no DuckDB) → run in parallel.
## Testing (deterministic; this is the "test correctly" answer)
- **Domain (no network):** fixed factor-input cross-section → assert exact z-scores (winsorized), composite, quantile membership, and each construction's weights (long Σ=1; ls Σ=0 & gross=2; tilt Σ=1, monotone in score); book-return = Σ(weight×asset-return); borrow-cost applied to ls shorts.
- **Universe screener:** fake supported-tickers + volumes → assert filter + top-N by dollar-volume.
- **Services:** fake `FundamentalsClient`/`DailyBarClient`/`UniverseSource` (deterministic fixtures, no network) → drive each construction through `ForwardTracker` → round-trip via `ForwardStateReader` (days-list summary); assert monthly-rebalance triggers + `extra` positions; ls books a borrow cost.
- **No lookahead:** forward-only (we only use data known as-of now) — inherent; documented.
- strict mypy, full suite green, two-stage review per task (spec then code-quality), faithful to B1's discipline.
## Discipline / caveats
- Factor premia are partly **crowded/decayed** — no edge is claimed; the **forward-gate + DSR** decide. Realistic small weighting expected.
- **Long-short realism:** borrow cost modeled (1%/yr default); assumes shortability of liquid large-caps (reasonable for top-N).
- **Point-in-time:** forward-only, so a reporting-lag lookahead cannot occur live; the future backtest layer MUST handle fundamentals reporting lag (flagged for that increment).
- Data cost: Tiingo Power limits (100k req/day, 108k symbols/mo) comfortably cover a 300-name monthly rebalance.
## Defaults (adjust if desired)
universe **top-300** by dollar-volume · **monthly** rebalance · short **borrow 1%/yr** · winsor ±3σ · quintile cut-offs.
## Build order (subagent-driven, next via writing-plans)
1. Ports: `FundamentalsClient` + `UniverseSource`.
2. `TiingoFundamentalsClient` (daily + statements) + fake.
3. `TiingoUniverseSource` (supported-tickers + dollar-volume rank) + fake.
4. Domain `equity_factor.py` (z-score/composite/winsor/quantile + 3 constructions + book return) — heavy unit tests.
5. Three `ForwardStrategy` services (long/ls/tilt) sharing factor compute.
6. Registry (3 entries) + 3 Dagster assets + cockpit_forward deps + Definitions.
7. Full gate + deploy + verify all 3 in cockpit.

GET https://apimedia.tiingo.com/docs/tiingo/daily/supported_tickers.zip

We download+parse it once (cached on the instance) and filter to US common stock:
assetType == "Stock", priceCurrency == "USD",
exchange ∈ {NYSE, NASDAQ, NYSE ARCA, AMEX, BATS},
and ACTIVE — endDate within ~7d of the file's max endDate (drops delisted names).
This yields thousands of candidates. It is NOT auth'd (public docs asset).

liquidity proxy, fine for RANKING). One snapshot, summed across chunks.
The FULL filtered candidate set is fed to the (auth'd, paid) IEX volume rank — no alphabetical
pre-slice — so "top-N by dollar-volume" ranks every liquid name, not just early-alphabet ones.
`max_candidates` (default 30000) is a runaway safety guard ONLY: it comfortably covers the entire

"""TiingoUniverseSource — top-N most-liquid US common stocks by trailing dollar-volume.
NO live network: the two fetch helpers (`_fetch_candidates` supported-tickers, `_fetch_volumes`
IEX snapshot) are monkeypatched to return fixed fixtures.
Invariants proven here:
(1) the supported-tickers candidate filter drops non-Stock assetType, non-US/foreign-currency,
and delisted (stale endDate) rows; valid active US stocks are kept.
(2) the FULL filtered candidate set is ranked by dollar-volume (last × volume), descending —
no alphabetical/file-order pre-slice (a late-in-file liquid name beats an early illiquid one).
(3) top_n(n) returns at most n tickers.
(4) max_candidates is a runaway safety guard only — it never trips for a normal set.
