(CALX) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (low volatility (β 0. 98), +509. 0% 10Y return).

Both have compounded well over 10 years (CALX: +509. 0%, WKEY: -91. 5%), confirming both are viable long-term holds — but the lower-volatility option typically results in less emotional selling during corrections.

Both stocks operate in the Technology sector, making this a peer-level intra-sector comparison — the same macro tailwinds and headwinds will affect both.
