2. The Co-Analyst
The Co-Analyst is not a chatbot. All answers are derived exclusively from source documents. We specialize in high-precision, multi-document queries. Here are a few important tips.
How to query the Co-Analyst
Use concise, straightforward language and clearly indicate the time period (e.g. most recent quarter).
Optionally, indicate the source materials to use, e.g. “from press releases only” and/or the output format e.g. “output in a single table”.
Complicated prompt engineering is not necessary and can hurt accuracy in some instances.
Queries to avoid:
- Follow up questions: Instead re-issue the complete query with additional instructions.
- Requests for information not available in sources: The Co-Analyst answers are derived exclusively from the source documents used in the query.
Source document selection for Co-Analyst query building:
The Co-Analyst answers are generated exclusively from the sources displayed on the right side of your answer. If you don’t see the answer you expect, re-issue the full query and specify which sources the Co-Analyst should use e.g. use all conference calls and 10-Qs for the last two quarters.

By default, the Co-Analyst will query either its content library (transcripts, releases, 10-Qs and 10-Ks , conference calls, presentations, and proxies) OR the web, depending on your query.
How to query the web through the Co-Analyst
To use web sources, simply add "per the web" or "use web sources" to your query.

If you prefer, you can select which sources to use by using Customize.

For any document not available in the default content library, navigate to the Filings & Transcripts tab to select it directly.

3. Forensic risk score & red flags (institutional tier)

Hudson Labs is well known for our proprietary forensic risk scores. These scores are unique because they rely entirely on non-numeric data in assessing the likelihood of fraud or malfeasance, providing a unique and significantly higher quality predictor of downside risk. Investors, insurers and accounting firms use our scores to find and avoid potential bad actors.
Hudson Labs risk scores are machine-learned, not additive. The scores are calculated using Hudson Labs’ AI-extracted red flags and reflect the interaction of these red flags/risks. Risk scores range from 1 to 100 (low risk to high risk).
Scores above 70 are considered high risk. Fewer than 10% of mid/large-cap issuers receive a Hudson Labs forensic risk score above 70. Companies with a high score have about a 1 in 3 chance of receiving an SEC enforcement action in the next three years. Scores from 60 to 70 are considered medium-high.
Risk scores are optimized for precision over recall. This means that high risk companies are very likely to experience future issues, but low risk companies may not all be in fact low risk.
Initial high risk scores tend to precede price collapse by 6 months or more. Risk scores are trained using 10+ years of SEC enforcement actions, regulatory investigations related to fraud, settled class action lawsuits and other target labels related to earnings management and malfeasance.
Hudson Labs risk scores predict fraud-related class action litigation. For example, we spotlighted Super Micro’s "hidden in plain view" risks two years before the stock freefall in 2024. See more case studies here.
Our risk analysis features cover filings since January 1, 2019 and are available for US companies only.
You can access the risk analysis features for any company under the “Red Flags” tab.
- Forensic risk score: See the full history of forensic risk scores identified for each of the annual and quarterly filings for the company.
- Most recent 10-K red flags: All red flags identified in the most recent 10-K filing by our general model. The model is trained to identify any verbiage that is associated with future probability of SEC enforcement action.
- Auditor turnover: There are a number of reasons why a public company may choose to change its accounting firm, including cost or reputation concerns. However, changes in audit firms can also be caused by tension between the management team and the team reviewing their work. These changes are therefore often considered to be a red flag. Hudson Labs provides access to auditor turnover tracking data for past 10 years, derived from the PCAOB database.
- Executive turnover: Hudson Labs uses proprietary AI modes to identify, tag and summarize turnover among executives and the board, as disclosed in 8-Ks. We track both appointments and departures (resignation, dismissal, retirement and death).
- Internal control weaknesses / Material weakness: Internal controls over financial reporting (ICOFR) are the systems and processes to make sure that the financial statements are correct. A material weakness in ICOFR means there was a failure in the company’s systems or processes that could have resulted in a misstatement in their financial statements that an investor would care about.
- Restatements: Companies disclose restatements to previous submitted financial statements in 10-Ks,10-Qs, and 8-Ks. All major restatements have Companies are obligated to disclose any major restatements of financial statements due to a material error, often called “Big R” restatements, in an 8-K.
- Non-timely filings: Non-timely forms e.g. NT 10-Ks are filed when a company is unable to meet the filing deadline set by the SEC. Non-timely forms may be an indicator of internal distress and therefore often cause or precede stock price declines
- Going concern warnings: Substantial doubt about an entity’s ability to continue as a “going concern” exists when the business faces the risk of a cash crunch or liquidity crisis in the next 12 months. This risk can be caused by insufficient revenue from operations, a large debt obligation coming due or other cash flow pressures. In short, substantial doubt about a company’s ability to continue as a going concern means there’s a real risk of bankruptcy.
- Concentrated related party risk: Hudson Labs uses proprietary AI models to identify higher-risk related party transactions and assess the concentration of related party risk across U.S. issuers. The use of language models means we can identify related party transactions, regardless of the wording or keywords and assess relative severity, facilitating advanced due diligence and market monitoring.
Our feeds are continuously updated as our AI models process new filings and call transcripts.
- Earnings calls: Find earnings calls added to the platform as soon as our models process them. We also provide the top three financial highlights from the earnings call.
- Earnings release: Each earnings release added to the feed comes with a three-point summary highlighting performance metrics and forward-looking commentary (where available).
- Forensic risk analysis feeds: We provide real-time feeds for a subset of our forensic risk features. The feeds contain a concise summary of the disclosure, focusing on the most important details.
- Material weakness
- Executive turnover
- Non-timely filings
- Restatements
- Going concern warnings
- SEC comment letters: Track SEC comment letters as they are made public. SEC’s Division of Corporate Finance (DCF or “The Division”) is responsible for reviewing securities filings. DCF staff issues a comment letter if it believes a company can better comply with a particular accounting rule or disclosure. The comment letter often contains a list of items that request additional information or disclosure, a modification to the filing or disclosure, or that the company changes how it discloses something in a future filing.
By default, our feeds are filtered to show companies with a market cap above US$300 m. Click on the Filters button on the top right of the feed to change the filters. Click on the “Watchlists” tab to only see the feed for companies in one or more of your watchlists.
