We all make investment mistakes, don’t we? I know I still do, even after 25 years. Investing for the long term, diversifying and minimising our trading to keep costs low will help avoid the most painful pitfalls, but here are a few of my favourite things to avoid:

Don’t spend your dividends

It’s easy to set share price growth as our target and see dividends as a bonus bit of cash to spend as it comes in. But we can see what a mistake that would be if we examine the 10-year performances of some FTSE 100 stocks.

A £10,000 investment in Diageo (LSE: DGE) a decade ago for example, would leave you with around £25,000 today — but reinvesting all those tasty dividends would have boosted that to £35,000!

Steer clear of “cash tomorrow” stocks

It can be very tempting when you see a company telling us of apparent profits and boasting great growth forecasts — but you need to check whether those accounting figures actually represent real hard cash.

Insurance outsourcer Quindell (LSE: QPP) has been reporting impressive profits, but much of it was deferred and accruals — some profits have been booked based on estimates long before they’ll even be invoiced.

Quindell shares have crashed by 90% since their peak after investors were scared off by poor cash flow.

Don’t just follow the crowds

When you see the latest big thing that everyone is talking about, it’s tempting, isn’t it? But when everyone else is buying, that’s probably about the worst time you could get in — the madness of crowds often sends prices rocketing before the inevitable crash.

Punters have pushed online fashion retailer ASOS (LSE: ASC) to sky-high valuations twice now, and twice it’s crashed again — and if you ask me, it’s still over-valued.

Don’t buy something you don’t understand

If you don’t understand how a business works, then don’t be a part owner of it.

The Oil business is one, and very few people know how to value a small explorer that isn’t making any profit yet. If you’d jumped on the Falklands bandwagon a few years ago and bought one of the handful of companies drilling in the area, you’d be forgiven for crying now.

Falklands Oil & Gas (LSE: FOGL), for example, has seen its share price collapse by 85% over the past five years, and hasn’t paid a penny in dividends.

Don’t listen to Warren Buffett

Well, he did buy heavily into Tesco (LSE: TSCO) just before the collapse, didn’t he? OK, no, I’m not actually suggesting you don’t listen to the experts — just don’t follow them blindly.

Do listen to what successful investors say and learn from how they work, but don’t forget to do your own research and make your own decisions for yourself based on your own investing preferences — it’s your money, and only you are responsible for it.
