KN vs RF: Which Is the Better Buy in 2026?
Last updated August 2026
Short answer
KN and RF are similarly sized, but RF trades noticeably cheaper on forward earnings (10.88x vs 22.62x): the market is paying up for KN's profile and pricing RF more conservatively, or for faster growth. Which you prefer comes down to the drivers you believe, and whether adding either over-concentrates what you already own.
KN vs RF: the tie-breaker metrics
Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | KN | RF | What it tells you |
|---|---|---|---|
| Forward P/E | 22.62 | 10.88 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Trailing P/E | 43.56 | 12.58 | Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price. |
| Beta | 1.59 | 1.01 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 73% of range | 84% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
| Price / book | 3.93 | 1.51 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Reading it: RF is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.
Before you buy: how KN and RF affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. KN and RF share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined KN and RF exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

What does Knowles Corporation (KN) do?
Knowles Corporation designs and manufactures specialized electronic components that perform critical, hard-to-replicate functions in demanding devices. It operates in two segments: Precision Devices (PD), which makes high-performance capacitors and radio-frequency and microwave filters for defense, medtech, industrial, and electrification markets, and MedTech & Specialty Audio (MSA), which makes balanced armature speakers, hearing-aid microphones, and specialty audio parts. After selling its lower-margin consumer MEMS microphone business, Knowles now positions itself as a focused supplier of differentiated, high-reliability components rather than a volume consumer-electronics vendor.
What does Regions Financial Corporation (RF) do?
Regions Financial Corporation is one of the largest US regional banks, headquartered in Birmingham, Alabama, with roughly 1,250 branches concentrated across the South, Midwest, and Texas. It operates three main segments: Consumer Banking (checking, savings, mortgages, and consumer lending), Corporate Banking (commercial and industrial loans, commercial real estate, and treasury management), and Wealth Management. As of Q1 2026 it carried about ~$132 billion in deposits and ~$98 billion in loans (Q1 2026), and it earns most of its money the classic banking way: the spread between what it pays on deposits and what it earns on loans and securities, plus fee income from treasury management, capital markets, wealth, and card services.
KN vs RF: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- KN drivers: Precision Devices growth; Margin and mix improvement.
- RF drivers: Net interest margin and rate positioning; Loan growth in a growing footprint.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Knowles is a small-cap supplier exposed to cyclical industrial, electrification, and defense budget swings, and a slowdown in any large end market could pressure results. For RF, as a regional bank, Regions is cyclical and exposed to the interest-rate path: falling rates can compress its margin, while sharp rate moves can pressure deposit costs and securities values.
KN or RF: which should you pick?
KN vs RF: the full fundamentals
KN. Revenue grew about 7 percent in 2025 and accelerated to roughly 16 percent year over year in Q1 2026, with non-GAAP EPS up about 50 percent that quarter. The stock trades near the upper end of its 52-week range (about $17 to $43), so the market is pricing in continued margin and cash-flow improvement. These are approximate figures drawn from recent filings and financial data providers.
RF. As of April 2026, Regions traded at a market capitalization of roughly ~$24 billion, a typical valuation range for a profitable super-regional bank. Its ~$1.06 annual dividend (yield near ~3.8%) and 13-year streak of increases make income a meaningful part of the return. Bank valuations are usually framed on price-to-tangible-book and price-to-earnings, and Regions' record ~18.26% return on tangible common equity in Q1 2026 is what supports its multiple.
Headline figures (approximate, July 2026): KN shows revenue (ttm) ~$610M, fy2025 revenue ~$593M, adjusted ebit (fy2025) ~$120M, adjusted free cash flow (fy2025) ~$114M; RF shows revenue (ttm) ~$7.4 billion, q1 2026 total revenue ~$1.87 billion, q1 2026 net income ~$539 million, q1 2026 diluted eps ~$0.62.

FAQ
What is the difference between KN and RF?
+
Knowles Corporation designs and manufactures specialized electronic components that perform critical, hard-to-replicate functions in demanding devices. Regions Financial Corporation is one of the largest US regional banks, headquartered in Birmingham, Alabama, with roughly 1,250 branches concentrated across the South, Midwest, and Texas. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is KN or RF the better stock?
+
Neither is universally better; they suit different views and risk levels. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, KN or RF?
+
On forward P/E (as of August 2026), KN trades at 22.62x and RF at 10.88x, so RF is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both KN and RF?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of KN vs RF?
+
KN: Knowles is a small-cap supplier exposed to cyclical industrial, electrification, and defense budget swings, and a slowdown in any large end market could pressure results. Customer and end-market concentration means a few large programs matter to the numbers. Acquisitions carry integration and valuation risk, and the shares trade at a premium that leaves limited margin for execution misses. Tariffs, supply-chain costs, and foreign-exchange movements can also weigh on margins given global manufacturing. Finally, competition from larger passive-component and audio suppliers could compress pricing over time. RF: As a regional bank, Regions is cyclical and exposed to the interest-rate path: falling rates can compress its margin, while sharp rate moves can pressure deposit costs and securities values. Credit quality is a standing risk, with net charge-offs at ~0.54% and nonperforming loans at ~0.71% in Q1 2026, both of which could deteriorate in a recession, particularly in commercial real estate. The 2023 regional-bank stress episode showed how quickly deposit confidence and funding can become the market's focus. Geographic concentration in the Southeast is a growth tailwind but also a source of correlated exposure to that region's economy. Regulatory capital rules, competition from larger money-center banks, and fintech disruption of fee lines round out the risks.
