A guy I used to work with would buy some shares in certain companies on a regular basis. The guy in question chose Coke, Pepsi, GE, Disney and some other old stable stocks. He just kept buying a few shared ($50 or so at a time) year after year after year. He worked his entire life, but by the time he was ready to retire, he had a pretty sizable investment; he was worth a rather tidy sum.

The moral of the story is, it is very much worth it to invest a bit at a time. Don't bother with the idea of buying high and selling low; not right now. Just go ahead and buy stable stocks (or shares of index funds) and wait them out. This strategy (mixed with other retirement tactics like a 401K from work, and IRA of your own, Social Security in the US) is a good way to build wealth.

Don't spend money you don't have, be ready for a long term investment and I think it makes great sense, regardless of what country you live in.

Small purchases will have a disproportionate expense for commissions. Even a $5 trade fee is 5% on a $100 purchase. So on one hand, it's common to advise individuals just starting out to use mutual funds, specifically index funds with low fees. On the flip side, holding stocks has no annual fee, and if you are buying for the long term, you may still be better off with an eye toward cost, and learn over time. In theory, an individual stands a better chance to beat the experts for a number of reasons, no shareholders to answer to, and the ability to purchase without any disclosure, among them. In reality, most investor lag the average by such a wide margin, they'd be best off indexing and staying in for the long term.

I think small sums invested regularly over long-term can do good for you, things to consider:

• Be careful with the costs
• Have goals and stick to them over the long term
• Spend only what you will not need within 5 years, if you invest in the stock market
• Try to find a tax-safe vehicle for your investment

I would go with an index fund and contribute there there regularly.
