42), 3. 6% yield). NovoCure Limited (NVCR) carries a higher beta of 2. 15 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (MDT: +24. 3%, NVCR: +38. 5%), confirming both are viable long-term holds — but the lower-volatility option typically results in less emotional selling during corrections.
