I am 57 and am told have 20k approx in Managed Growth Fund.Pension matures at 60 so should i extend to 65 years and invest in Cash and global equities such as Bloxim High Yield fund (Risky), please advise.
I don't think that there is nearly enough information on your post for someone to give you a 'good' answer.
I think you really need to sit down with someone (other than your bank) and go through all the information with them. Just pay them a fee for their time and recommendations.
I note from your previous posts that you were seeking an opinion from the bank advisor as to what you should do. Did this ever get this?
