RF vs TTMI: Which Is the Better Buy in 2026?

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.

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.

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. RF and TTMI 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 RF and TTMI 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.

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.

TTM Technologies (Nasdaq: TTMI) makes technologically advanced printed circuit boards, RF and microwave components, and mission-systems assemblies. The name stands for time-to-market, reflecting a one-stop design, engineering, and manufacturing model. Its two anchor end markets are aerospace and defense (roughly 44% of sales, backed by a record backlog of about $1.61 billion as of early 2026 and multi-year programs like a $200 million Raytheon LTAMDS radar award) and data center and networking (about 36% of sales), where demand has surged with AI-driven interconnect complexity. The company has invested in domestic capacity, including a new Ultra-HDI plant in Syracuse, New York, and announced planned all-cash acquisitions of Swiss Technology Group and ILFA expected to close in the third quarter of 2026.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• RF drivers: Net interest margin and rate positioning; Loan growth in a growing footprint.
• TTMI drivers: AI data center interconnect demand; Aerospace and defense backlog.

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: 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. For TTMI, pCB manufacturing has historically been cyclical and capital-intensive, and a slowdown in AI capital spending or defense budgets would pressure both anchor markets.

Pick RF if you believe its drivers more; TTMI if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the RF and TTMI guides.

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.

TTMI. TTM delivered record first-quarter 2026 net sales near $846 million with an adjusted EBITDA margin around 16%, and raised guidance on AI and defense demand. The stock re-rated sharply into 2026, reaching an all-time high near $224 in June before pulling back. Trailing and forward multiples sit well above TTM's multi-year averages, reflecting high growth expectations.

Headline figures (approximate, APRIL 2026): 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; TTMI shows revenue (ttm) ~$3.1B, fy2025 revenue ~$2.91B, q1 2026 revenue ~$846M (up ~30% YoY), q1 2026 non-gaap eps ~$0.75.

RF and TTMI are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined RF and TTMI exposure against your real portfolio. It is not an investment adviser.
