There are two main ways to transfer stocks and investments between trading accounts, either via an ‘in specie’ transfer or as cash. An ‘in specie’ transfer is known as a stock transfer - that means transferring your assets in their current form whether it’s stocks and shares or unit trusts and mutual funds. Stock transfers allow you to keep hold of your investments alongside any changes in value. The downside is that it can take up to four weeks to transfer your holdings.
