Apple designs consumer electronics, software, and services, led by the iPhone, Mac, and a growing high-margin services segment. It is one of the world's most valuable companies and a core holding in most large-cap and technology index funds.
KLA makes the process-control and inspection systems chipmakers rely on to detect defects during semiconductor manufacturing.
The useful starting point is not which ticker has performed better. It is whether the two companies convert the same economic forces into revenue and cash flow in the same way. AAPL is classified by the SEC as Electronic Computers, while KLAC is classified as Optical Instruments & Lenses. The different industry codes are a warning against treating sector membership as proof of identical economics.
