100 Days of Volatility (NKTR)


Or a more volatile one. Nektar Therapeutics (ticker: NKTR), a biopharmaceutical company with a $13 billion market cap, topped the list as the most volatile stock during the 100-day periods we looked at in both 2017 and 2018. It was even a touch more volatile last year, averaging a 2.97% move on a daily basis, to 2.93% this year.

Clearly, Nektar’s volatility can be attributed to a few huge daily moves in reaction to the company’s positive news. Last year, shares of Nektar soared over 42% in just one day after the company reported encouraging data for a Phase 3 clinical trial of its back-pain treatment. This year, the company agreed to take an upfront fee of $1.85 billion from Bristol-Myers Squibb (BMY) in exchange for 35% of the potential profit of a solid-tumor cancer treatment. It’s a good reminder that more than macroeconomic conditions matter for stocks.

But it might also be a special case.
