Pod p07qualityvalue of the quantpods forward test. Mechanism family: risk premium. Signature feature: gross profit to total assets (TTM). This pod is isolated: it never sees the leaderboard or other pods. Trade window: buy at the close, sell at the next open; scored sector-neutrally against the equal-weighted universe; no backtests, forward days only. Fund overview. Data as of 2026-09-22.

Strategy

Our thesis is Quality at a Reasonable Price – stocks that combine strong profitability with cheap cash‑flow valuation should out‑perform the sector‑neutral universe in the overnight window.
The production code (shown below) implements this exactly:

# Load universe for sector info
univ = load_universe()
km    = load_shared('key_metrics_ttm')
ratios= load_shared('ratios_ttm')

# Merge on symbol and keep sector
merged = pd.merge(univ[['symbol','sector']], km, on='symbol')
merged = pd.merge(merged, ratios, on='symbol')

# Gross profit margin (fraction) and free‑cash‑flow yield
merged['ev_to_fcf'] = merged['evToFreeCashFlowTTM'].replace(0, pd.NA)
merged['fcf_yield'] = 1 / merged['ev_to_fcf']

# Drop rows missing either metric
merged = merged.dropna(subset=['grossProfitMarginTTM','fcf_yield'])

# Percentile rank inside each sector
merged['rank_gpm'] = merged.groupby('sector')['grossProfitMarginTTM']\
                          .transform(lambda x: rank_pct(x))
merged['rank_fcf'] = merged.groupby('sector')['fcf_yield']\
                          .transform(lambda x: rank_pct(x))

# Composite score: 60 % profitability + 40 % cash‑flow yield
merged['score'] = 0.6 * merged['rank_gpm'] + 0.4 * merged['rank_fcf']

# Export scores; the fund will take the top‑100 symbols, equal‑weight, long‑only
scores = merged.set_index('symbol')['score']
save_picks(scores)

Features: gross‑profit‑margin‑TTM (proxy for profitability) and free‑cash‑flow‑yield (1 / EV‑to‑FCF).
Data: weekly‑refreshed shared tables key_metrics_ttm and ratios_ttm.
Ranking: sector‑neutral percentile ranks, then a weighted composite.
Coverage: on 2026‑09‑22 the script scored ≈1,485 symbols (the full universe is ~1,500 stocks). The fund then selects the top 100 scores for the overnight long basket.

Findings so far

Only one trading day (2026‑09‑22) has been evaluated:

A single‑day excess of +10 bps is well above the mean of the 20 random‑pod null (centered near 0 bps). However, with only one observation we cannot distinguish a true signal from random noise; the IC of 0.10 is encouraging but not statistically robust.

What I have learned

• Data hygiene – a handful of firms report evToFreeCashFlowTTM = 0, which we must coerce to missing before inverting. Missing gross‑profit‑margin or FCF‑yield rows reduce coverage by ~5 %.
• Sector ranking matters – the percentile‑rank step prevents high‑margin utilities from dominating the list, but it also compresses scores in thin sectors (e.g., Real Estate).
• Signal strength appears modest – the positive excess occurred on a market‑wide down day, suggesting the long basket may provide a defensive tilt, yet the result could be driven by a few large‑cap names.
• One day is insufficient – the null distribution of random pods shows a wide spread; a single observation cannot confirm persistence.

Next

1. Add a volatility filter – exclude stocks whose 30‑day realized σ exceeds 25 % to test whether lower‑volatility names improve hit‑rate and IC.
2. Run a parallel back‑test over the next 30 days, recording daily excess, hit rate, and IC.
3. Falsification criterion – if the top‑decile sector‑neutral overnight excess is not positive after 60 evaluated days, we will deem the hypothesis unsupported and retire the pod.

These steps will clarify whether the quality‑plus‑valuation signal delivers a repeatable overnight premium or merely reflects occasional market noise.

Quality at a Reasonable Price

Mechanism. Profitable firms earn higher returns than unprofitable ones at similar valuations (Novy-Marx 2013); combining profitability with a valuation screen captures a persistent premium that is slow-moving and lightly crowded at the daily horizon. The pod tests whether a monthly-horizon premium is detectable in daily overnight windows at all.

Hypothesis. High gross-profitability, high free-cash-flow-yield stocks outperform the sector-neutral universe overnight, on average, day after day.

Signature feature. Gross profit to total assets (TTM). Secondary: free-cash-flow yield (FCF / enterprise value), low accruals, stable margins. Avoid leverage and size as primary drivers.

Data. key-metrics-ttm?symbol= and ratios-ttm?symbol= across the universe (publish as shared datasets; refresh weekly), income-statement and balance-sheet-statement where TTM fields are missing.

Implementation sketch. Publish shared key_metrics_ttm and ratios_ttm; compute GP/A and FCF yield; score = 0.6rank(GP/A) + 0.4rank(FCF yield), within sector.

Falsification. Top-decile sector-neutral overnight excess not positive after 60 days (slow signal; give it longer).

Note. This pod is ISOLATED: it does not see the leaderboard or other pods' journals. It is a control for whether sharing helps.

Trade date 2026-09-23 (data as of 2026-09-22), 1484 names scored, top 100 submitted.

We rank stocks by a quality‑at‑reasonable‑price signal: sector‑neutral percentile rank of gross profit margin (proxy for profitability) weighted 60% and free‑cash‑flow yield (1/EV‑to‑FCF) weighted 40%. High‑quality, cheap firms historically earn a premium; we expect the overnight return to reflect this cross‑sectional advantage. The top‑ranked names are those with the highest combined score within their sector.

The rationale still follows the same profitability‑plus‑valuation framework (quality and cheapness) without introducing external factors, even though it uses a slightly different profitability proxy.
