Shares

When you buy shares, you're buying a small part of a company. You can buy shares directly or own them through a managed fund that pools many investors’ money.

Shares are riskier than other types of investments such as bonds and cash investments. If you own shares, you’re not guaranteed a return or capital gain, but they potentially offer a higher return, particularly over the long term.

Investing Myth #5: 'Real investors play the share market'

Share can be highly volatile but you can earn returns by dividends and capital gains. There are two ways you can make money:

  • Dividends - These are payments made to shareholders as a way of sharing profits
  • Capital gains - This is the money you make if you sell your shares for a higher price than you paid.

Shares go up and down in value a lot. This is normal – shares are volatile. You can view the value of New Zealand listed shares on the NZX website.

Companies with shares listed on a licensed financial product market like the exchange run by NZX Limited have to comply with the rules of the exchange.

Information varies depending on the type of shares

Only some types of share offers will have a Product Disclosure Statement (PDS). Share this! explains the difference between buying shares on primary and secondary markets and the different levels of disclosure that apply to these markets.

Initial Public Offer (IPO)

This is the process of publicly offering shares to investors and listing on the share market. An IPO (also called a float or listing) may involve the issue of new shares to raise more capital for the company or the sale of shares previously owned by other shareholders.

Unlisted shares may be hard to sell

Unlisted shares aren’t on an exchange and there may not be an established market for their sales.

The value of your shares might fall

The company you’ve invested in could perform poorly or fail. The share price could stay weak for a long time if the company consistently disappoints investors. Dividends may also fall if profits fall, or the company decides to keep more of its profits to reinvest in the business.

Your shareholding may be reduced

This can happen when the company you’ve invested in offers to sell you new shares to raise money but you don’t take up the offer. It can also happen when the company raises capital using complex investments that can cause your initial investment to be sharply reduced if you don’t know what to do with them.

Information about the share market and investing in shares can get quite technical and along with that comes a lot of specialised language and jargon. See our simple guide to sharemarket jargon.

The fees charged will vary depending on the type of share buying service you choose. You will pay a minimum brokerage fee for each order placed and may have to pay a percentage fee for any amount over the minimum.

Make sure you understand the company you’re buying shares in and the key risks it faces.

Diversify

You should aim for a mix of different shares to smooth out the ups and downs in value that typically happen. Diversifying doesn’t guarantee you won’t make any losses but done properly, it will help you manage your risk.

It's important to keep track of your shares' performance.

Invest for the long term

Holding shares for the long term enables you to smooth out price fluctuations. If you buy shares with money you’re going to need soon, you take the risk of being forced to sell at a low price.

Don’t try and time the market

No one can predict with certainty how a share will perform. Trying to pick a good time to buy or sell involves some luck, so make sure you’re fully informed about what you’re buying or selling, and why.

Keep up to date

The performance of your shares will change over time. The company annual report will help you stay up to date with the business you’re investing in. See our additional resources:

Be wary of low-ball offers

A ‘low ball’ offer is an unsolicited offer to buy shares from you at significantly below the market price and/or where payment is spread over a long period of time.

‘Unsolicited’ means you don’t know the person making the offer and the offer is not part of an offer process such as share buyback from the company whose shares you hold or a takeover. More about Low Ball offers.
