If what follows could ever be described as a 'strategy'....
Financial Advice ?
Note that I'm not a financial adviser and nor would I recommend that you shell out your hard-earned readies in seeking so-called 'professional' investment advice. Do your own research.
(There's a proviso to this, however, in that I wouldn't be averse to asking my accountant for information on how a particular financial instrument would be treated for tax purposes. Trading accounts, ISAs and SIPPs etc are simple enough vehicles for most people to readily understand their tax treatment, but there are many things out there that aren't – the UK tax code runs to several thousand pages, and like most tax 'rules' they are not designed to be definitive but are deliberately left open to interpretation....generally though, if you can't fully understand an 'opportunity' yourself, without taking external advice, then it may be more prudent not to pursue it at all.)
Having established and understood what are the particular tax advantages or otherwise of the investment type or wrapper in which they're held, there's absolutely no-one out there who is qualified to advise you in which particular industry sectors, shares, funds, bonds, trackers, commodities etc you should invest.
