 The coronavirus pandemic has accelerated the adoption of telehealth services, and few companies are profiting from the trend more than Teladoc Health NYSE: TDOC. The medical care platform provider could be overvalued; the company is not profitable yet, and is currently trading at 19.3 times sales and 15.5 times projected sales. The telehealth industry has grown by 80 since last year, spurred on by the spread of the coronavirus, but could become more of a norm rather than a temporary trend.
