A hidden gem Pro-dex has been growing sales per share at a cagr of 18.66% from 2015 to 2019. Sales in the last ttm has been $36.18 compared to $34.83 in 2019. The company currently has a return on equity of 31.3% which has been consistently high over many years. With the recent pullback and a P/E ratio of around 18 I think it's a great buying opportunity.
