How to choose an Index fund for your Portfolio?

Index and Funds is the only way for a low capital portfolio to own a host of amazing companies in your portfolio. Buying a single share of Amazon, Google, Facebook and Apple each would cost you almost $3,000. However, some index or funds allows you to own these four companies and other quality companies with a low capital of $100. This would encourage a self-investor to save more money every month for a contribution.
