The PEG ratio (P/E divided by earnings growth rate) is the most growth-adjusted single valuation metric: MGIC Investment Corporation wins at 0. 44x versus Essent Group Ltd.

By this metric, MGIC Investment Corporation (MTG) is the more undervalued stock at a PEG of 0. 44x versus Essent Group Ltd. 's 2. 23x.

In this comparison, RDN (2.

8% yield), MTG (2. 2% yield), ESNT (1. 8% yield), AGO (1. 7% yield) pay a dividend. MBI does not pay a meaningful dividend and should not be held primarily for income.

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

43), 2. 2% yield, +333. 0% 10Y return). Both have compounded well over 10 years (MTG: +333. 0%, MBI: +197. 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.

Both stocks operate in the Financial Services sector, making this a peer-level intra-sector comparison — the same macro tailwinds and headwinds will affect both.

In terms of investment character: AGO is a small-cap deep-value stock; MBI is a small-cap high-growth stock; RDN is a small-cap deep-value stock; MTG is a small-cap deep-value stock; ESNT is a small-cap deep-value stock. AGO, RDN, MTG, ESNT pay a dividend while MBI does 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.
