01), +120. 6% 10Y return). Applied Materials, Inc.

These companies operate in different sectors (CPSH (Technology) and AEIS (Industrials) and MKSI (Technology) and COHU (Technology) and AMAT (Technology)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.
