Regarding investments, you dont give enough (i.e. any) information about why you want an investment portfolio, what you are trying to achieve, what are your other financial priorities/circumstances etc.
If I were an advisor I'd be asking:
- What % of your overall wealth is this 5K...is it 1%, 10% or is it your life savings
- Have you any high interest debts like car loan/credit card etc
- Have you an SVR mortgage
- Have you a rainy day fund of 3-6 months salary
- Have you a pension
- Have you kids
- Are you married
- Have you any investment property
- What exactly constitutes success for this investment portfolio
- How long are you happy to be without this money
- What would you do if value dropped 30% overnight
Most people when asked why they want to invest generally say "I want to get better return than in normal bank account"......that is not a goal, thats a vague pipe dream that you cannot quantify.
There are lots of similar threads on this forum (and on boards investments forum), I'd suggest having a good read of them as well before deciding what to do.
