Tip #9 - Diversification

by Tony Ryburn, Executive Chairman, Sharesight | Jul 9th 2013

Every week we post a tip that we hope will help you become a successful share market investor.

Tip #9 — Diversification

When it comes to investing, diversification is important for two reasons: it can potentially protect you against undue losses if investments in a particular company, sector or asset class fail, and it can actually improve the overall return of your portfolio. For these reasons it has been described as the only free lunch in investing but it is important not to go overboard. Diversification does not guarantee success and if it’s overdone it adds complexity and has the potential to dilute rather than improve returns.
