Spread bets and CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage. 70% of retail investor accounts lose money when trading spread bets and CFDs with this provider. You should consider whether you understand how spread bets and CFDs work and whether you can afford to take the high risk of losing your money. 

Professional clients trading spread bets and CFDs can lose more than they deposit.

The value of shares, ETFs and other ETPs bought through a share dealing account, a stocks and shares ISA or a SIPP can fall as well as rise, which could mean getting back less than you originally put in. Past performance is no guarantee of future results. Some ETPs carry additional risks depending on how they’re structured, investors should ensure they familiarise themselves with the differences before investing.

Crypto - Don’t invest unless you’re prepared to lose all the money you invest. This is a high-risk investment, and you should not expect to be protected if something goes wrong. Take 2 mins to learn more.
