(FORM) a "Buy" — based on 19 analyst ratings — the highest consensus in this comparison. The "better buy" depends entirely on your goals: growth investors should weight revenue trajectory, value investors should weight P/E and PEG, and income investors should weight dividend yield and streak.
02Which has the better valuation — FORM or KLAC or TER or NVMI or ONTO?
On trailing P/E, KLA Corporation (KLAC) is the cheapest at 50.2x versus FormFactor, Inc. at 111.1x. On forward P/E, KLA Corporation is actually cheaper at 41.8x. The PEG ratio (P/E divided by earnings growth rate) is the most growth-adjusted single valuation metric: Onto Innovation Inc. wins at 0.34x versus FormFactor, Inc.'s 4.70x — a PEG below 1.0 traditionally signals the market is underpricing earnings growth.
03Which is the better long-term investment — FORM or KLAC or TER or NVMI or ONTO?
Over the past 5 years, Nova Ltd. (NVMI) delivered a total return of +389.9%, compared to +104.3% for FormFactor, Inc. (FORM). A $10,000 investment in NVMI five years ago would be worth approximately $49K today (assuming dividends reinvested). Over 10 years, the gap is even starker: NVMI returned +40.1% versus FORM's +1201%. Past returns do not guarantee future results, and the stock with the higher historical return may already have its best growth priced in.
04Which is safer — FORM or KLAC or TER or NVMI or ONTO?
By beta (market sensitivity over 5 years), KLA Corporation (KLAC) is the lower-risk stock at 1.76β versus Onto Innovation Inc.'s 2.24β — meaning ONTO is approximately 28% more volatile than KLAC relative to the S&P 500. On balance sheet safety, Onto Innovation Inc. (ONTO) carries a lower debt/equity ratio of 1% versus 130% for KLA Corporation — giving it more financial flexibility in a downturn.
05Which has better profit margins — FORM or KLAC or TER or NVMI or ONTO?
KLA Corporation (KLAC) is the more profitable company, earning 33.4% net margin versus 9.1% for FormFactor, Inc. — meaning it keeps 33.4% of every revenue dollar as bottom-line profit. Operating margin tells a similar story: KLAC leads at 43.1% versus 8.5% for FORM. At the gross margin level — before operating expenses — KLAC leads at 62.3%, reflecting greater pricing power or product mix advantage. Stronger margins indicate durable pricing power, lower cost of revenue, or higher mix of software/services. They are one of the clearest signs of business quality.
06Is FORM or KLAC or TER or NVMI or ONTO more undervalued right now?
The PEG ratio (forward P/E divided by expected earnings growth rate) is the most precise measure of undervaluation relative to growth potential. By this metric, Onto Innovation Inc. (ONTO) is the more undervalued stock at a PEG of 0.34x versus FormFactor, Inc.'s 4.70x. A PEG below 1.0 is traditionally considered the threshold for growth-adjusted undervaluation. On forward earnings alone, KLA Corporation (KLAC) trades at 41.8x forward P/E versus 55.4x for FormFactor, Inc. — 13.6x cheaper on a one-year earnings basis. Analyst consensus price targets imply the most upside for ONTO: 21.2% to $261.67.
07Which pays a better dividend — FORM or KLAC or TER or NVMI or ONTO?
In this comparison, KLAC (0.4% yield), TER (0.2% yield) pay a dividend. FORM, NVMI, ONTO do not pay a meaningful dividend and should not be held primarily for income.
08Is FORM or KLAC or TER or NVMI or ONTO better for a retirement portfolio?
For long-horizon retirement investors, Teradyne, Inc. (TER) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (+1598% 10Y return). Nova Ltd. (NVMI) carries a higher beta of 1.83 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (TER: +1598%, NVMI: +40.1%), 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.
09What are the main differences between FORM and KLAC and TER and NVMI and ONTO?
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.
