What the rules cover
These are the kinds of wording FINRA Rule 2210's content standards describe, according to its text and FINRA's social media guidance, and how they tend to show up in broker-dealer communications.1,4
| Phrase or term | In practice |
|---|---|
| "Will double", "can't miss" | Promissory or exaggerated claims, listed in the content standards among what communications may not include. |
| "Expected to return 12%" | A projection of performance, generally excluded by the text apart from limited exceptions. |
| "Risk-free", "safe as cash" | Benefits described without a fair and balanced treatment of the risks. |
| Influencer and other paid posts | Third-party posts a firm paid for or helped shape can count as the firm's own communications. |
| Client testimonials | Shown without the disclosures the text describes, such as whether the person was paid. |
| Retail ads and social posts | Retail communications are approved by a registered principal before use, with limited exceptions. |
| "FINRA approved" | Wording that implies FINRA endorsement or approval of the firm or its products. |
FINRA has already settled cases under Rule 2210 over social media and online communications.
A brokerage app settled FINRA charges after paying social media influencers whose posts included claims that were not fair and balanced.
A brokerage firm was fined by FINRA over crypto-related retail communications that did not give a fair and balanced picture of benefits and risks.
Where it goes wrong
One approved claim ends up in many channels, markets and languages. Along the way it gets shortened, translated and reworded, and some versions end up using the very phrases you are trying to avoid.
"The Income Fund aims to pay monthly income. Risks are explained in the prospectus."

FAQ
Almost everywhere your firm talks to investors. FINRA's social media guidance describes third-party posts a firm has paid for or adopted as the firm's own communications,4 and we usually find covered content in:
Treat every paid post as a firm communication from the start. Give influencers the approved wording and the phrases to avoid, ask for each post before it goes live, keep the approved version and check what was actually published against it. Our marketing compliance page shows how teams track this.
Keep the approved version, who approved it and when, the date of first use, whether it was filed with FINRA, and every channel and language it's published in. When a post is reworded or translated, record that version too, so you can trace it back to its approval.
How it applies to a specific communication is a question for your legal adviser. Where that communication appears across your markets and languages is a question Arbitr answers.
Find every live version first: the firm's own channels, reps' social accounts, influencer posts and partner pages. Then match each to its approval. If you also advise clients as an investment adviser, the SEC Marketing Rule covers those advertisements, and other markets are on our financial promotions hub.
As any written communication distributed or made available to more than 25 retail investors within any 30-calendar-day period, according to its text. Correspondence goes to 25 or fewer retail investors in that period.1
They're separate rules from different regulators. Rule 2210 covers FINRA member firms' communications with the public, according to its text,1 while the SEC Marketing Rule covers advertisements by SEC-registered investment advisers.
Most companies do, and it works for the file it reviews, in the language it reviews, before a campaign ships. It doesn't cover what's published afterwards: the market versions, the agency reworks, the sales deck built from the campaign six months later. That's a volume problem, not a failure of your legal team.
