One of the best parts of the market to look for growth shares in my opinion is the mid cap space. I think in this area there are a large number of shares that have the potential to grow into much bigger entities over the next decade. Here's why I think these three shares could be among the best mid cap growth shares on the market right now: Bellamy's Australia Ltd (ASX: BAL) This organic infant formula company's share price performance in 2018 has been thoroughly disappointing. The cause of this underperformance has been delays to it being granted its accreditation to sell Chinese-labeled products in China and also the sales disruption caused by the launch of a new formulation. While this is disappointing I think it is well worth holding on for the long term. Especially how Bellamy's management remains confident it will hit $500 million in sales in FY 2021. Bravura Solutions Ltd ( ASX: BVS ) Another top mid cap growth share to consider is Bravura Solution.
