Shares of DNA sequencing leader Illumina (NASDAQ: ILMN) soared 17% the day after CEO Francis deSouza presented at the 2017 J.P. Morgan Healthcare Conference. The big news was the launch of a new family of sequencers that could reenergize sales of high-end instruments, something that investors were hoping for and that I discussed as a possibility last week. The new line, called NovaSeq, will likely renew the company’s growth, but not immediately.
