"Analyzing HealthCor Partners' Q3 2016 vs. Q4 2019 Holdings: RTI Surgical Tops Portfolio, CORINDUS VASCULAR ROBOTICS I Sees Complete Divestment"

In today's investment landscape, it can be difficult to keep up with the ever-changing holdings of major funds. That's why we're breaking down the changes in HealthCor Partners Management LP's Q3 2016 vs. Q4 2019 13F Holdings Comparison.

First, let's take a look at the biggest gainer in HealthCor's portfolio - RTI Surgical Holdings Inc. (Sym: SRGA). In Q3 2016, HealthCor didn't hold any shares of the company, but by Q4 2019, they had accumulated a staggering 1,432,939 shares. This increase resulted in a change of over 100%, making RTI Surgical Holdings Inc. one of HealthCor's top holdings.

Meanwhile, on the opposite end of the spectrum, HealthCor completely divested from three companies: CORINDUS VASCULAR ROBOTICS I (Sym: CVRS), NATERA INC (Sym: NTRA), and ALEXANDRIA REAL ESTATE EQUITIES (Sym: ARE). Of these three, CORINDUS VASCULAR ROBOTICS I saw the greatest drop in ownership. HealthCor held 24,943,042 shares in Q3 2016, but by Q4 2019, they had sold their entire stake - indicating a complete lack of confidence in the company's future success.

Another interesting trend to note is HealthCor's lack of new investments in the health and medical technology sector. In Q3 2016, HealthCor held 14 companies in this sector, but by Q4 2019, that number had decreased to just 12. While it's not a significant change, it does suggest that HealthCor may be shifting its focus to other industries.

One company that stands out in HealthCor's current holdings is Vertex Pharmaceuticals Inc. (Sym: VRTX). HealthCor held 340,239 shares in Q3 2016, and by Q4 2019, that number had increased to 858,451. This change represents a 152% increase in ownership and suggests that HealthCor has high hopes for the pharmaceutical company's future.

Finally, we can't ignore the impact that these portfolio changes have had on HealthCor's bottom line. In Q3 2016, the value of their holdings was $49,819,000. By the end of Q4 2019, that number had decreased to $28,959,000 - a decrease of 42%. This drop in value is largely due to the complete divestment from CORINDUS VASCULAR ROBOTICS I, NATERA INC, and ALEXANDRIA REAL ESTATE EQUITIES.

In conclusion, HealthCor Partners Management LP has undergone some significant changes in their portfolio over the past three years. While they've made some savvy investments, such as in Vertex Pharmaceuticals Inc., they've also divested from entire companies that they once held promising positions in. Only time will tell if these moves pay off, but one thing is for certain: investing is a constantly evolving game, and even the most successful funds must adapt to changing realities.
