Applied Materials, Inc. (AMAT) carries a higher beta of 2. 19 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (SELX: -96. 3%, AMAT: +21. 4%), 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.

These fundamental differences mean investors should not choose between them on a single metric — the "better stock" depends entirely on which of these characteristics aligns with your investment strategy.
