Me and my sister have taken on a challenge for 2021. We are both going to invest £1,000 in the next few weeks then in April 2022 we are going to come together and see who has made the most money on their investment. The investment doesn't need to have matured by then but we will see whose is performing the best.
The trouble is that I have zero investing experience beyond buying Premium Bonds ten years ago 
So I would appreciate a little bit of a steer in the right direction if someone can, please. It's vital that I beat my sister
