Here’s a local company where, if you had invested $8,000 a year ago your investment would be worth $43,000 today.

Arden Hills-based IntriCon’s stock has surged in value by more than 500 percent within the last year (45 percent within the last month alone), and a stock analyst firm last week came out with a strong “buy” recommendation, saying the stock should go up another 14 percentage points within the near future.

When Stifel, Nicolaus & Co. increased its price target for the company to $50, it was trading at $43.78 a share. This morning the stock is at $45 a share.

IntriCon makes wireless, miniature body-worn devices for medical, hearing-health and professional audio use. It’s a major supplier to Medtronic’s diabetes division and employs about 600 people.

Minneapolis-based Dougherty & Co. is also a market maker for this company.
