These companies operate in different sectors (KOSS (Technology) and AAPL (Technology) and AMZN (Consumer Cyclical) and SONY (Technology)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.

In terms of investment character: KOSS is a small-cap quality compounder stock; AAPL is a mega-cap quality compounder stock; AMZN is a mega-cap quality compounder stock; SONY is a mid-cap deep-value stock. SONY pays a dividend while KOSS, AAPL, AMZN do not, making them suitable for different income and tax situations.
