Investment decisions are made by professional fund managers appointed by the trustees. These managers make annual charges.
Every day the trustees compute the value of the trust, divide it by the number of units in issue, and produce a bid and offer price based on that calculation. Unfortunately, when you invest in a unit trust, you usually never know the price you will be charged for units until the next valuation point, typically midday the following day.
Unit trusts are well suited to regular savers who want to drip-feed money into the market every month. With unit trusts, you can invest as little as $50 per month, averaging the acquisition cost of your shares over many months.
Many unit trusts make an initial charge when you invest, and their management charges are deducted from fund income.
