Good luck , I'm not sure if your a total novice like myself or are familiar with investing. If I could offer some advice in investing I would say have a clear plan and stick with it, if you are going to invest every 3/6/9 whatever months then set a reminder or phone or PC and follow it through ignore the news , there will always be be someone predicting a crash etc.
Really try imagine how you would feel if you invest and that money you invested halved in value the week after you invested , try hard to imagine it losing 10% a week for a few weeks are you going to pull it out.
Discipline is the key to success imo, Ive made a good few mistakes since I started investing last year, I wasn't as educated and still aren't but I'm getting there , the tax treatment plays on my mind still , I'm noticing that individual shares move in line with the whole market eg if the s&p500 drops 3% most individual shares drop between 1-4% , for some reason I would have expected that not to be the case , I would have expected more shares to be up and down , but that could be just the climate we are in at the moment where the whole stock market is just dropping on China news . (sorry I'm waffling on!) but my point was in gathering more confidence that eventually i may go the direct share route instead of index investing . It's possible of course to do both side by side.
If you download the holdings of say MSCI world and see just exactly what you own for one share it gives me anyway confidence that your getting massive diversification , I worried a lot about loss relief but in fact you are getting loss relief against the other shares in the basket if you get me so it's not a huge disadvantage . All the best look forward to the blog. Not many of the knowledgable regulars that post advice here (very good advice ) actually share what they are invested in (sarenco I'm looking at you and Jim !) so well done for taking the plunge !
