Analysts rate CACI International Inc (CACI) a "Buy" — based on 29 analyst ratings — the highest consensus in this comparison.

(LDOS) is the cheapest at 11. 8x versus Castellum, Inc. at 24. 9x. On forward P/E, Deluxe Corporation is actually cheaper at 6. 6x — notably different from the trailing picture, reflecting expected earnings growth. The PEG ratio (P/E divided by earnings growth rate) is the most growth-adjusted single valuation metric: Deluxe Corporation wins at 0. 12x versus CACI International Inc's 1. 44x — a PEG below 1. 0 traditionally signals the market is underpricing earnings growth.

Over the past 5 years, CACI International Inc (CACI) delivered a total return of +85.

4%, compared to -45. 3% for Castellum, Inc. (CTM). Over 10 years, the gap is even starker: CACI returned +416. 4% versus CTM's -45. 3%. Past returns do not guarantee future results, and the stock with the higher historical return may already have its best growth priced in.

In this comparison, DLX (4.

5% yield), SAIC (1. 6% yield), LDOS (1. 2% yield), CTM (0. 2% yield) pay a dividend. CACI does not pay a meaningful dividend and should not be held primarily for income.

For long-horizon retirement investors, Science Applications International Corporation (SAIC) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (low volatility (β 0.

26), 1. 6% yield, +104. 4% 10Y return). Castellum, Inc. (CTM) carries a higher beta of 2. 22 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (SAIC: +104. 4%, CTM: -45. 3%), 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.

These companies operate in different sectors (CTM (Technology) and CACI (Technology) and DLX (Communication Services) and SAIC (Technology) and LDOS (Technology)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.

In terms of investment character: CTM is a small-cap high-growth stock; CACI is a mid-cap quality compounder stock; DLX is a small-cap deep-value stock; SAIC is a small-cap deep-value stock; LDOS is a mid-cap deep-value stock. DLX, SAIC, LDOS pay a dividend while CTM, CACI do not, making them suitable for different income and tax situations. 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.
