The stock of little-known IntriCon, maker of lower-cost hearing aids and other tiny medical devices, surged by nearly 30 percent in value last week amid huge trading volume as buyers warmed to its financial outlook and recent favorable federal legislation. .
As a result, the Arden Hills-based company is trading at its highest prices in nearly a decade.
On Tuesday alone, "IIN" closed up nearly 10 percent to $11.25 per share, on volume that ranged from five times to 20 times normal trading levels for a company that had traded less than 10,000 shares daily on average.
The brass at IntriCon, which is now valued at nearly $80 million, aren't sure who was buying the stock.
"We are always out talking to new investors," said longtime CEO Mark Gorder. "We raised about $4 million last year and brought in Heartland Funds. But we know it's not those folks buying.
"More people seem interested in the logic of what we are doing and the [recent federal] law adds credibility."
In late August, President Donald Trump signed the U.S. Food and Drug Administration Reauthorization Act, which includes a provision that allows adults with mild to moderate hearing loss to access over-the-counter hearing aids without being seen by a hearing care professional.
Several of the world's largest hearing aid companies, which dominate the hearing market and also are at least partial owners of thousands of retail audiologist shops, opposed the legislation. That includes Twin Cities-based Starkey Hearing Technologies and the locally based North American headquarters of Amplifon and ReSound. They sell hearing aids under various brand names.
