AMT vs HLDCY: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of October 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.

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. AMT and HLDCY 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 AMT and HLDCY 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. Walnut is not an investment adviser.

American Tower Corporation (NYSE: AMT), founded in 1995 and headquartered in Boston, is a real estate investment trust that owns, operates, and develops multitenant communications real estate. Its core business is leasing vertical space on wireless towers to mobile network operators, government agencies, and broadcasters under long-term contracts with annual escalators, generating 97% of 2025 revenue from property operations. Beyond towers, AMT owns CoreSite, a portfolio of 30 U.S. data centers offering colocation and interconnection services to enterprises, cloud providers, and network operators, which has become a fast-growing second revenue engine. The company manages nearly 150,000 communications sites across the Americas, Europe, Africa, and Asia-Pacific, providing global scale that smaller peers cannot easily replicate.

Henderson Land Development Company Limited builds and sells homes in Hong Kong, owns a large portfolio of offices, shopping centres and hotels, and holds big stakes in other listed companies. In the six months to June 30, 2026 group revenue was HK$17.2 billion, up 80%, of which property development supplied HK$11.8 billion and property leasing HK$3.36 billion, with department stores (Citistore and Unicorn), hotel rooms and other businesses making up the rest. Most of the profit comes from three sources the company calls its pillars: Hong Kong flat sales, rental income from completed investment properties, and its share of listed subsidiaries and associates, chiefly The Hong Kong and China Gas Company (Towngas).

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

• AMT drivers: 5G Densification and Mid-Band Upgrades; CoreSite and AI-Driven Data Center Demand.
• HLDCY drivers: Hong Kong flat sales and the unbooked pipeline; Central Yards and The Henderson.

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: The most immediate risk is customer concentration: in 2025, four carriers (T-Mobile at 18%, AT&T at 17%, Verizon at 14%, and Telefonica at 10%) collectively represented roughly 59% of total revenue, so any material lease dispute, consolidation event, or technology shift (such as carriers building private networks or relying on low-earth-orbit satellites) could disproportionately hurt results. For HLDCY, the clearest risk is that Hong Kong residential demand fades after a strong first half: the company itself said the central government's tightening of capital outflow controls slowed the property sector toward the end of June 2026.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick AMT if you believe its drivers more; HLDCY 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 AMT and HLDCY guides.

AMT. AMT's trailing P/E of approximately 27x is well below its own 3-year average of roughly 45x and its 10-year average of roughly 56x, reflecting both earnings normalization after a period of large one-time items and a broader re-rating of rate-sensitive REITs in a higher-for-longer interest rate environment. For tower REITs, investors typically focus on AFFO per share rather than GAAP earnings, because the latter is heavily influenced by depreciation and one-time currency gains or losses. On that basis, FY 2025 delivered high-single-digit AFFO per share growth, and management's 2026 guidance projects continued quarterly revenue in the $2.67 billion to $2.77 billion range per quarter, suggesting mid-single-digit full-year growth if realized.

HLDCY. On trailing underlying profit the shares trade at roughly 16 times earnings, but that multiple is flattered by the first-half land-resumption gain, so it overstates how cheap the recurring business is. The more common yardstick for Hong Kong developers is the discount to net asset value, and at ~HK$27 against reported NAV of HK$67.25 the stock trades at about 0.4 times book. The gap reflects doubts about appraised values, a loss-making mainland book and family control. The dividend yield uses the 2025 total of HK$0.50 interim plus HK$0.76 final; the 2024 total had been HK$1.80.

Headline figures (approximate, 2026-06-27): AMT shows revenue (q1 2026) ~$2.74 billion, revenue (fy 2024, most recent full year) ~$10.13 billion, adjusted ebitda (q1 2026) ~$1.84 billion (margin ~67%), affo per share (q1 2026) ~$2.84 (up ~3.3% year-over-year); HLDCY shows revenue (ttm to june 2026) ~HK$33.4B (~US$4.3B), underlying profit (ttm) ~HK$8.1B (~HK$1.67 per share), market cap ~HK$130B (~US$16.7B) at ~HK$26.90, net asset value per share HK$67.25 (June 30, 2026).

AMT and HLDCY 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 AMT and HLDCY exposure against your real portfolio. It is not an investment adviser.
