I use spread bets to get exposure to gold. I sb futures and the spread is extremely low, nowhere near 7%. Further I only have to deposit 3% so to gain exposure to £10k I have to have £300 in my account, as a precaution for volatility I hold a balance of at least 25% of the exposure in bank account (ie for £10k I have £2.5k in a bank account which off sets against my mortgage, so is earning about 6% pa). I try to get the furthest forward futures I can and then either sell and buy forward futures or roll the bet over to the next future available. I currently have circa £45k exposure to gold which is about 15% of my portfolio.
