Hi aj,
I don't deal with Acorn Life so this opinion is a personal rather than a professional one. (Professionally I'm only authorised to offer advice on products from companies with whom I hold an agency.)
There are two aspects of this bond that I wouldn't be keen on.
(1) The performance of each company is capped at 10% when calculating the performance of the overall basket. This is a subtle but very important point. Performance of the overall basket is already capped at 10%. But this clause makes it virtually impossible for the basket to achieve 10% at all. If you think about it, for a basket of any 24 shares to achieve 10% on average, some will achieve less than 10% and some will achieve more, making up an average of 10%. But if those that achieve more are individually capped at 10%, then those that achieve less will drag the average performance of the basket down below 10%.
(2) Dividend income from any of the shares is not included in the calculations. This is common to most tracker bonds.
