RE: Seen SENX on the list from IG.21 Feb 2021 21:54
Hi Pure - One way to gain exposure to a share rather than purchase it is to use a derivative like a CFD or Spreadbet where you are betting on the increase/decrease of the share price. You have to put a margin (deposit) down on the share rather than the full price.
So for example you could gain exposure to £10k worth of SENX by putting down 25% or £2.5k deposit. If the price then moves 10% you would stand to make £1k profit or a return of 40% on your original stake of £2.5k. Obviously you can ratchet the losses up quickly as well.
IG are basically asking for 100% margin on certain shares, making a CFD not really worth while.
I don't use SBs but I think they involve betting on a share price being up or down over a fixed period of time 3, 6, 9, 12 months, etc.
