As of yesterday's close, year-to-date the All Ordinaries (Index: ^AXAO) (ASX: XAO) had managed to push higher by a solid 6.7% to 6,103 points.
While this is a strong gain, it is nothing compared to some of the gains being made by constituents of the index.
Here's why these shares have more than doubled in value this year:
The A2 Milk Company Ltd (ASX: A2M) share price has rallied almost 250% higher since the turn of the year thanks largely to the strong demand for its infant formula in China. This ultimately led to the company reporting a 68.9% increase in sales to NZ$262.2 million during the first four month of FY 2018. Considering its infant formula consumption value share in China stands at just 3.5%, its growth in the nation could only just be getting started.
The Kidman Resources Ltd (ASX: KDR) share price is up 188% since the start of 2017. Investors have been fighting to get hold of the lithium miner's shares due to the world-class potential of its Mt Holland operation. The company has signed a 50:50 joint venture with Sociedad Quimica y Minera de Chile to develop a lithium refinery that will allow for production of both lithium hydroxide and lithium carbonate, putting it in a great position to profit from the high prices that lithium commands. I would consider Kidman as an investment if its shares fell back a touch.
The Kogan.com Ltd (ASX: KGN) share price has rocketed 261% year-to-date after the online retailer outperformed its prospectus forecasts and diversified its business greatly through additional offerings such as broadband, mobile plans, and insurance. While I have been thoroughly impressed at its performance this year, I feel its shares are a little expensive at 135x trailing earnings. Especially with Amazon recently launching in Australia. While its launch may ultimately prove to be a win for Kogan, I'm sitting on the fence with this one until I have seen proof that they can both operate in the market successfully.
