Who else wants 4 market-beating stock ideas for the next 10 years?

If you're looking to invest in the sharemarket over the long term, for both its capital gains and income-generating potential, there are a few things you should look for in any of the stocks you buy, including:

1. A durable competitive advantage
2. A track record of delivering above average shareholder returns
3. A sound management team, and,
4. A reliable dividend yield

If you can find companies with these four characteristics, you'll be well on your way to building a portfolio capable of market-beating returns.

To make life a little easier, here are four companies which I believe have the ability to deliver above average portfolio returns.

1. Washington H. Soul Pattinson & Co. Ltd (ASX: SOL) is a diversified holding company with large stakes in businesses like TPG Telecom, Ruralco, Brickworks and more. Over 100 years old, Soul Patts has done a great job of maintaining and growing its business for many years. At today's prices, it's forecast to yield a dividend of 3.6% fully franked.
2. Slater & Gordon Limited (ASX: SGH) is Australia's largest personal injury law firm. The company's fully franked dividend yield of 1.2% might not seem like much now, but with ample growth opportunities in front of it and plenty of room to grow its payout, if your holding for the long term now could be a good time to buy some shares.
3. Woolworths Limited (ASX: WOW) is a household name right across the country and a favourite income stock for many investors. After a recent share price fall, Woolworths looks to be much better value now than it was six months ago. Indeed, with a 4.2% fully franked yield, it could be worthy of spot in investors' portfolios.
4. Computershare Limited (ASX: CPU) is frequently referred to as a 'growth stock' but given its excellent defensive qualities, including geographical diversification and a recurring revenue base, it could also be considered a core holding in any portfolio. Whilst it's currently offering a 2.7% dividend with partial franking, analysts are forecasting strong earnings per share and dividend growth well into the foreseeable future.
