Is it acceptable for a salesperson to say 'Your principal is absolutely guaranteed' or 'It will definitely go up'?

Making conclusive statements about uncertain matters, or leading consumers to mistakenly believe they are certain, constitutes unfair solicitation under the Financial Consumer Protection Act.

Expressions in advertisements for investment-type products that give the misleading impression that losses will be compensated or profits guaranteed are also prohibited. If you hear such statements, check the risks in the product description yourself and, if necessary, contact the financial company or the Financial Supervisory Service.
