22), 2. 6% yield, +166. 6% 10Y return). Sight Sciences, Inc. (SGHT) carries a higher beta of 2. 41 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (ABT: +166. 6%, SGHT: -83. 9%), confirming both are viable long-term holds — but the lower-volatility option typically results in less emotional selling during corrections. Retirement portfolios generally favour predictability over maximum returns. Consult a financial advisor before making allocation decisions.
