7% yield, +350. 2% 10Y return). Both have compounded well over 10 years (QCOM: +350. 2%, ARLO: -32. 6%), 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.

These companies operate in different sectors (VIOT (Consumer Cyclical) and TUYA (Technology) and ARLO (Industrials) and AMZN (Consumer Cyclical) and QCOM (Technology)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.

In terms of investment character: VIOT is a small-cap deep-value stock; TUYA is a small-cap high-growth stock; ARLO is a small-cap quality compounder stock; AMZN is a mega-cap quality compounder stock; QCOM is a large-cap quality compounder stock. TUYA, QCOM pay a dividend while VIOT, ARLO, AMZN do not, making them suitable for different income and tax situations.
