These 4 shares are the S&P/ASX 200’s best performers: Should you buy them?

Despite the impact of the Brexit and the Trump presidency victory, the Australian share market has had a stellar 12 months.

During this time the benchmark S&P/ASX 200 (Index: ^AXJO) (ASX: XJO) has smashed expectations and put on an impressive gain of 11.8%.

Four shares on the index which did a lot of the heavy lifting are listed below. Here’s why they are the best performers on S&P/ASX 200 during the last 12 months:

The a2 Milk Company Ltd (Australia) (ASX: A2M) share price has surged higher by 80% in the last 12 months. The growing popularity of the dairy company’s infant formula products in the lucrative China market has been the catalyst for this gain. The company was given an additional boost recently when the Chinese government delayed new cross border e-commerce laws indefinitely. Its shares do look expensive now, but could still provide significant value for patient long-term investors.

The Aristocrat Leisure Limited (ASX: ALL) share price has rocketed 95% since this time last year. Significant market share gains and growing profit margins in the United States, Australia, and digital social gaming segments have been the key to its incredible performance. As a result management expects full-year profit to grow in the range of 20% to 30% compared to the prior corresponding period. At 35x trailing earnings its shares are by no means cheap, but I could still see them climbing higher if it delivers on the top end of its full-year guidance.

The Webjet Limited (ASX: WEB) share price has risen a remarkable 86% in the last 12 months. It’s not hard to see why investors have been snapping up shares in Webjet during this time. Thanks to continued growth in organic bookings and market share gains from all of its businesses, the online travel agent delivered a stunning 86.9% increase in half-year net profit after tax. I expect more of the same in the second-half and in FY 2018. This could make it an opportune time to make a buy and hold investment.

The Whitehaven Coal Ltd (ASX: WHC) share price has been the biggest mover on the index in the last 12 months with a massive 256% gain. The catalyst for this has been rising coal prices due to a combination of production cuts in China and strong demand from its steelmakers. As I’m not overly bullish on coal prices moving forward, I wouldn’t be surprised to see the Whitehaven Coal share price come under significant pressure in the next 12 months. In light of this, it is one to avoid in my opinion.

Finally, here are three explosive shares which I think could make this list in 12 months time. Each is growing like gangbusters at the moment.

Top 3 ASX Blue Chips To Buy In 2017

For many, blue chip stocks means stability, profitability and regular dividends, often fully franked..

But knowing which blue chips to buy, and when, can be fraught with danger.

The Motley Fool's in-house analyst team has poured over thousands of hours worth of proprietary research to bring you the names of "The Motley Fool's Top 3 Blue Chip Stocks for 2017."

Each one pays a fully franked dividend. Each one has not only grown its profits, but has also grown its dividend. One increased it by a whopping 33%, while another trades on a grossed up (fully franked) dividend yield of almost 7%.

If you're expecting to see the likes of Commonwealth Bank, Telstra and Wesfarmers shares on this list, you'll be sorely disappointed. Not only are their dividends growing at a snail's pace, their profits are under pressure too due to the increasing competitive environment.

The contrast to these "new breed" blue chips couldn't be greater... especially the very real prospect of significant share price gains, something that's looking less likely from the usual blue chip suspects.

The names of these Top 3 ASX Blue Chips are included in this specially prepared free report. But you will have to hurry. Depending on demand - and how quickly the share prices of these companies moves - we may be forced to remove this report.
