5% revenue growth year-over-year, versus 9. 7% for RTX Corporation (RTX).

(ERJ) a "Buy" — based on 21 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.

On trailing P/E, Companhia Paranaense de Energia (ELPC) is the cheapest at 4.

3x versus The Boeing Company at 93. 2x. On forward P/E, Companhia Paranaense de Energia is actually cheaper at 3. 2x. The PEG ratio (P/E divided by earnings growth rate) is the most growth-adjusted single valuation metric: Companhia Paranaense de Energia wins at 0. 12x versus GE Aerospace's 3. 33x — a PEG below 1. 0 traditionally signals the market is underpricing earnings growth.

Over the past 5 years, Embraer S.

A. (ERJ) delivered a total return of +412. 7%, compared to -1. 9% for The Boeing Company (BA). Over 10 years, the gap is even starker: RTX returned +233. 5% versus ELPC's +77. 1%. Past returns do not guarantee future results, and the stock with the higher historical return may already have its best growth priced in.

By beta (market sensitivity over 5 years), RTX Corporation (RTX) is the lower-risk stock at 0.

50β versus GE Aerospace's 1. 19β — meaning GE is approximately 137% more volatile than RTX relative to the S&P 500. On balance sheet safety, RTX Corporation (RTX) carries a lower debt/equity ratio of 59% versus 10% for The Boeing Company — giving it more financial flexibility in a downturn.

5% versus 9. 7% for RTX Corporation (RTX). On earnings-per-share growth, the picture is similar: Embraer S. A. grew EPS 118. 2% year-over-year, compared to -17. 6% for Companhia Paranaense de Energia. Over a 3-year CAGR, GE leads at 16. 3% annualised revenue growth. Higher growth typically commands a higher valuation multiple — check whether the premium P/E or P/S is justified by the growth rate using the PEG ratio.

GE Aerospace (GE) is the more profitable company, earning 19.

0% net margin versus 2. 5% for The Boeing Company — meaning it keeps 19. 0% of every revenue dollar as bottom-line profit. Operating margin tells a similar story: GE leads at 19. 1% versus -6. 1% for BA.

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.

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, Companhia Paranaense de Energia (ELPC) is the more undervalued stock at a PEG of 0. 12x versus GE Aerospace's 3. 33x. A PEG below 1. 0 is traditionally considered the threshold for growth-adjusted undervaluation.

In this comparison, ELPC (21.

8% yield), RTX (1. 5% yield), GE (0. 4% yield), BA (0. 2% yield) pay a dividend. ERJ does not pay a meaningful dividend and should not be held primarily for income.

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

50), 1. 5% yield, +233. 5% 10Y return). Both have compounded well over 10 years (RTX: +233. 5%, GE: +117. 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.

These companies operate in different sectors (ELPC (Utilities) and ERJ (Industrials) and GE (Industrials) and BA (Industrials) and RTX (Industrials)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.

In terms of investment character: ELPC is a small-cap deep-value stock; ERJ is a mid-cap high-growth stock; GE is a large-cap high-growth stock; BA is a mid-cap high-growth stock; RTX is a large-cap quality compounder stock. ELPC, RTX pay a dividend while ERJ, GE, BA 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.
