Regular investment plans are flexible. If you have to face an unexpected expense or, on the contrary, you receive a large sum of money, you can stop, reduce or increase the amount of your regular payments.
Regular investment may be an interesting option, especially when the interests on the savings accounts are at an historic low. However, don’t forget the basic principles of prudence: don’t rush into a regular investment plan without having beforehand examined the question from all sides and got the maximum of information from your financial institution.
