(CIX) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (low volatility (β 0. 50), 9. 3% yield, +223. 2% 10Y return). NN, Inc. (NNBR) carries a higher beta of 2. 04 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (CIX: +223. 2%, NNBR: -75. 7%), confirming both are viable long-term holds — but the lower-volatility option typically results in less emotional selling during corrections.
