Top Medical Device Biotech Growth Stocks Catch Fire (SWAV, EMED, IRTC, MDT, ZYXI, ECOR, NVCR, TIVC, ZBH, ISRG)

After posting the worst first half of any year since 1970 (1), the stock market has come roaring back to life in Q3, with technology and risk bets leading the way following Fed Chair Jerome Powell’s signal at the July FOMC meeting of a possible shift in policy bearing. (2)

The Fed believes it is already at the fabled “neutral policy rate” meaning that investors may not have to content with endless hikes in the Fed’s battle against the inflation bogey man. (3)

Stocks are back in style with retail investors, who are bidding up growth plays in a frenzy of speculative fervor.

One of the groups that stands to fare best under these new conditions is the biotechnology space, where the landscape is defined by risky bets on long-term prospects with a potentially huge payoff down the line.

Within that space, right at the crossroads of technology and biotechnology is a sweet spot that has been receiving strong attention from investors over recent weeks – the medical device technology space.

With that in mind, we take a closer look at some of the most interesting stories in the medical device segment of the biotech space this week.
