Dubious websites may offer too-good-to-be-true investment opportunities (e.g. pre-IPO stocks of fabricated companies sold at huge discounts, or funds with guaranteed multiple returns) that do not actually exist. Alternatively, such websites may be fraudulent copycat websites imitating the websites of reputable financial institutions to lure investors to part with their money and/or disclose personal information that the fraudsters may later use to swindle investors.

Do not respond to investment website offers unless you are sure of the legitimacy of the entity.
