Check every letter against the full security or fund name.
Confirm stock, fund, ETF, bond, or another instrument.
Use current issuer pages, prospectuses, and regulatory filings.
Review source dates, fees, risks, restrictions, and updates.
1. Confirm the exact symbol
Check every character and match it with the full name shown by a primary source. Similar symbols may identify unrelated securities, while an old symbol may survive in articles after a merger or reorganization.
2. Confirm the security type
Determine whether you are looking at common stock, preferred stock, a mutual fund, ETF, closed-end fund, bond, option, depositary receipt, or another instrument. The product type determines which documents and risks matter.
3. Confirm the issuer or sponsor
Find the company’s investor-relations site or the fund sponsor’s product page. Match the legal name, class, exchange or fund family, and any identifier such as a CUSIP.
4. Check official filings
- For public companies: SEC company filings and current reports
- For mutual funds and ETFs: prospectuses, shareholder reports, and fund filings
- For corporate actions: issuer and exchange notices
- For a brokerage order: the security description in the final preview
5. Review fees, risks, holdings, and history
Read costs and risk disclosures before performance tables. Check what the product holds, how concentrated it is, what could cause loss, and whether historical results shown are comparable and net of relevant expenses.
6. Use multiple reputable sources
Primary sources establish identity and current disclosures. Independent tools can make comparison easier. Cross-check dates, methodologies, and definitions rather than assuming two similarly labeled numbers measure the same thing.
7. Treat social-media claims as leads, not evidence
Urgency, certainty, screenshots without dates, undisclosed positions, and promises of outsized returns are reasons to slow down. Trace every material claim back to a filing, issuer statement, or documented methodology.
8. Save your sources and note the date
Keep the documents that informed your research and record when you reviewed them. Facts can change after earnings, a prospectus supplement, a merger, a distribution, or a symbol change.
