Since the election, the S&P 500 Health Care Index has fallen 0.3%, compared with a 1.5% decline in the Standard & Poor's 500-stock index. Year to date, the index is up 16%, making it the third-best performing sector after financial and consumer-discretionary stocks.
…PerkinElmer Inc. (PKI), a manufacturer of X-ray machines, has risen 56%.
It’s astonishing that anyone would characterize PKI as a maker of X-ray machines. The author must be confusing it with some other company.
