General research and statistical measurement. Not tailored to the recipient's investment objectives, financial situation, or needs. Not investment advice, a recommendation, or an offer to buy or sell any security. Marnello LLC is not a registered investment adviser and does not manage client assets or exercise discretion over any account.
Marnello LLC provides quantitative research, statistical measurement, performance attribution, and risk reporting to professional and institutional recipients. Deliverables describe historical characteristics of securities, portfolios, factors, or return series. They contain no ratings, price targets, or position recommendations, and express no opinion on the advisability of investing in, purchasing, or selling any security.
No Marnello product accepts a recipient's risk tolerance, investment objectives, time horizon, or financial circumstances as an input. Holdings submitted for analysis are processed as a data set to be measured. Nothing in any deliverable is a suitability opinion on any holding or portfolio for any person.
Marnello LLC does not hold client assets, does not have trading authority over any account, and does not execute transactions. API access, added after commercial launch, is read-only.
All fees are fixed subscription fees, fixed per-file fees, fixed licence fees, or fixed project fees. No fee is based on the performance of any account or security, and Marnello LLC takes no commission, revenue share, or payment from any fund, index provider, exchange or data vendor named in its research.
Backtested and simulated figures are hypothetical: computed from historical data under stated assumptions, gross of transaction costs unless stated, not the results of actual trading or of any account, and not achievable by any investor. Not prepared for use in the recipient's advertising. Past characteristics do not forecast future behaviour. Validation records, including out-of-sample results and transaction cost sensitivity, accompany every published factor and state their limitations. Sample issues are produced on publicly available daily prices. The universe is the current S&P 500 constituent list and market capitalization uses current share counts, so the figures carry survivorship bias; each document states this in its data note.
Holdings submitted for analysis are processed under a defined retention policy and are not used for any purpose other than producing the requested deliverable. Marnello LLC holds no account credentials or account access.
Recipients are solely responsible for their own regulatory obligations, including any obligation to substantiate advertising claims, and for how Marnello output is presented to their clients or regulators. Deliverables are licensed for the recipient's internal use and may not be redistributed or resold without written consent.
