You don't need to pick the next big company. Most long-term investing comes down to three ideas.
1. Index funds: buy the whole basket
An index fund (often bought as an ETF on the stock exchange) holds every company in a list, such as the 200 biggest in Australia. You get the market's return, less a small fee, without trying to guess winners. Low fees matter, because fees come out every year whether returns are good or bad.
2. Spread it around
Don't put everything in one company, one industry or one country. If one part has a bad year, the others can soften the hit. A mix of Australian shares, overseas shares, bonds and cash is the usual starting point. How much of each depends on when you'll need the money.
3. Time in the market
Markets go up and down, sometimes sharply. Over long periods, staying invested has generally done better than jumping in and out trying to dodge the drops. Investing a set amount regularly takes the guesswork out of timing.
- Pay off high-interest debt such as credit cards first.
- Keep a cash buffer for emergencies so you're not forced to sell in a dip.
- Money you need within about five years usually doesn't belong in shares.
- Remember your super is already invested. Check what it's in.
Where it gets taxed
Dividends and interest are taxed each year at your rate. Sell for a profit and capital gains tax applies, with a 50% discount if you held the investment for more than 12 months.
Past performance is not a reliable indicator of future performance.
