Here's Why Exact Sciences Gained 14.1% in December

Shares of Exact Sciences (NASDAQ: EXAS) jumped over 14% last month, according to data from S&P Global Market Intelligence. The cancer screening and diagnostic test leader announced new long-term data from two large population studies of Oncotype DX Breast Recurrence Score, suggesting the diagnostic can be used to inform treatment options for low-risk individuals successfully treated for breast cancer.

The updated data set reinforces the value proposition behind the merger between Exact Sciences and Genomic Health. In addition, last month's trek higher helped the pharma stock to end the year on a high note following a tumble that began in September. Shares posted a 46% gain in 2019.
