Alternative Data

Alternative data matters for this project because every target market has a physical or flow-driven counterpart that conventional price and fundamental feeds only capture with a lag. For the energy contracts (MCL, QM, BZ), satellite tank-top measurements, AIS tanker tracking, and flaring detection front-run the weekly EIA and monthly OPEC/IEA statistics that everyone else trades on — Wood Mackenzie's Cushing report, for example, is delivered two days ahead of EIA and is explicitly marketed as a WTI-trading input. Weather is the other big physical channel: Gulf-coast hurricane risk shuts in refining and production capacity that prices straight into WTI/Brent spreads, and degree-day demand data feeds energy-complex demand models — all available free from NOAA.

For the equity-index contracts (ES/MES, NQ/MNQ, YM, RTY/M2K), the highest-value "alternative" datasets are actually flow calendars. The FTSE Russell reconstitution — which moved to a semi-annual June + December cycle in 2026 — is the single largest predictable liquidity event in RTY/M2K; quarterly futures roll windows are tracked by CME's free Equity Quarterly Roll Analyzer; and corporate buyback blackout windows, by sell-side desk estimates, remove the market's largest single buyer for weeks around each earnings season. Retail order-flow proxies (Nasdaq RTAT, Quiver, Unusual Whales) and attention proxies (Google Trends, Wikipedia pageviews) are cheap and genuinely accessible at retail budgets.

Honest budget framing up front: the institutional satellite and AIS vendors (Kayrros, Ursa, Kpler, Vortexa, Spire) price in the tens of thousands of dollars per year and are effectively out of retail reach. They are documented here so the project knows what the "smart money" sees and when — Kayrros inventory updates daily, Genscape's Cushing measurements land twice weekly. The realistic retail alt-data stack for these markets is: free NOAA/Open-Meteo weather, free EIA-930 electricity, free Wikimedia pageviews, free event calendars (Russell recon, roll dates, blackout estimates), free CFTC-adjacent CTA proxies (SG Trend Indicator), plus low-cost subscriptions (Quiver ~$30/mo, SerpApi $25–75/mo for Trends, ADS-B Exchange ~$10/mo) — with TankerTrackers.com ($1,000/mo) as the cheapest credible tanker-intelligence option, still steep for retail.

Corporate buyback blackout calendar (estimated)

FieldValue
What it isNo official source exists — blackout windows are company-policy conventions (typically ~2 weeks to a month before earnings through 1–2 days after). Sell-side desks (Goldman, Morgan Stanley, JPMorgan) publish % of S&P 500 in blackout; these estimates circulate in media (EBC explainer; ISABELNET chart archive; SSGA study PDF)
CoverageES/MES, NQ/MNQ, YM — corporate bid withdrawal around each earnings season (late Jan, late Apr, late Jul, late Oct)
GranularityWeekly estimates of % of index market cap in blackout
History depthMedia-relayed desk estimates only; a DIY series can be rebuilt from any earnings calendar (blackout ≈ T-30d to T+2d per company)
Latency / updatesQuarterly cycle; e.g. media relayed Goldman desk estimates of ~40% of companies in open windows in May 2026 rising to ~100% by late May (Advisor Perspectives) (unverified — article blocked automated access 2026-07-11)

Kpler (incl. ClipperData, MarineTraffic, FleetMon, Spire Maritime AIS)

FieldValue
What it isThe consolidated commodity-flows and ship-tracking giant: cargo-level tracking of crude/products plus AIS. Acquisitions: ClipperData (2021), JBC Energy & COR-e (2022) (Kpler blog), MarineTraffic & FleetMon (closed March 2023) (PRNewswire), and Spire Global's maritime AIS business — acquisition completed April 25, 2025 for ~$241M (Kpler press release); the businesses continued operating independently pending a UK CMA review at closing (corrected as of 2026-07-11)
CoverageCrude/condensate, products, LNG/LPG, dry bulk flows — direct MCL/QM/BZ relevance; import/export nowcasts ahead of official data
GranularityCargo-level (vessel, grade, origin/destination, volume); terminal-level
History depthCrude flows back to ~2013 (ClipperData heritage) — verify per commodity module
Latency / updatesNear-real-time AIS + analyst-confirmed cargo matching
Access methodTerminal/web platform, REST/GraphQL API, Excel add-in
CostContact sales. Unofficial: Vendr reports median $55,000/yr, range $50,000–$73,800/yr (as of 2026-07-11, Vendr Kpler page) — labeled unofficial
Pricing pagehttps://www.kpler.com/
Licensing / redistributionEnterprise licence; module-based; no redistribution
Reliability caveatsCargo attribution partly inferential (grade/volume estimates); dark-fleet (sanctioned) cargoes deliberately hide — see TankerTrackers for that niche
Best forGold standard for waterborne crude flow data — if budget ever allows; otherwise use its free weekly insight posts

Vortexa

FieldValue
What it isEnergy cargo-tracking and freight analytics — Kpler's main competitor (vortexa.com)
CoverageWaterborne crude/products/LNG; freight; full cargo history of every tanker >5,000 dwt (unverified — dwt threshold not found on current product page, 2026-07-11)

What it isPackaged corporate-jet movement intelligence: JETNET JetTrack (the dataset Bloomberg distributes: Bloomberg JetTrack overview PDF) and Gordon Haskett's Jet Tracker research product (Integrity Research). Reality check on the signal: a 2018 Oxford study found statistically significant M&A predictive power in corporate flight paths, and the famous 2019 Occidental-jet-in-Omaha spot preceded Buffett's $10B investment (Marcellus recap); Quandl's pioneering corporate-jet dataset (WatersTechnology, 2019) passed to Nasdaq — current listing status Unknown — verify
