In reply to elliot.baker:
There's a range of companies offering similar stuff. The choice is mainly price-driven.
Costs are in three groups:
- Account fees. Either a flat amount per quarter or a percentage.
- Trading costs. Either a flat fee or a capped percentage.
- Fund fees (if you buy funds). Almost always a percentage.
If you have a small amount overall (say <£100k) then the percentage account fees look better. When you have more, then the fixed fee wins. A search will show you the top 20 and where the tipping point is.
Trading. Don't. Day traders don't win. It might be better to save your monthly investment and purchase once a quarter. Think of the cost of trade (and stamp duty) as a percentage. If it's more than 1% you might think about waiting and pooling.
Fund fees are the hidden differentiator. A FTSE tracker can cost 1% a year or 0.06%. This is the single biggest difference between funds. Obviously this is irrelevant if you're picking stocks (but see the odds on "Trading", above).
FWIW I use interactive Investor (switched from iWeb). I only buy indices and with geographic spread. I don't stock pick or trade and I choose funds with minimal charges. That is still a fairly "adventurous" approach. I wrote a script to download the entire funds database and sorted by charges and then picked broad trackers with good mechanics and dividend reinvestment. The only thing I would like is to be able to rebalance a little (for example the FTSE is skewed overly to the top 20 companies), but that's easily addressed by buying some 250 or other indices.
Having said that 100% of trackers underperform the market - but only by a little bit. 75% of managed funds underperform, on average by much more and the charges are 10x.
