Stryker is expected to gain significant knee market sharedriven by the demand of its MAKO total knee application . It expects to see an incremental market share gain attributable to the MAKO total knee application in 2018. Today, the company is the second-largest player in the knee implant market. Zimmer Biomet Holdings (ZBH) is the leading market player. Johnson & Johnson (JNJ) and Smith & Nephew (SNN) are the other big players in this market space. If you’re interested in taking a diversified exposure to the potential growth opportunity of Stryker, you can invest in the Vanguard S&P 500 ETF (VOO), which holds ~0.21% of its total holdings in SYK.
As I've been saying Stryker's robotic arm is seen as a major threat to other companies Knee business including ZBH. Zimmer's knee revenue comprises 36% of their gross sales. A hit to this will significantly hurt them going forward. Seriously Zimmer needs to make a move ASAP so its prepared to capitalize on acquisition for Spine in 2018; not sure when dental might hit market.
Let me add that China is seen a very important target market!
