The best strategy for investment is to find a low cost fund, at a low cost broker and invest for the long term.

First off, you should try to buy a property - maybe the biggest that you can sensibly afford. Next you should put 90% of your money into those low cost funds that were mentioned, ideally in a fund that has shares in as many companies worldwide as possible, as this will lower your risk and give you the best return. That last 10% you could have fun with and maybe try to buy some speculative assets.
