I’ve been looking at hospital stocks for 2026 recently and found this sector to be quite interesting. Although there were some fluctuations early in the year, after a careful analysis, it turns out that hospital stocks all have their own investment logic.

First, let’s talk about why you should look at hospital stocks. Simply put, healthcare services are a necessity. No matter how the economy is doing, people still get sick. This is why hospital stocks are called defensive stocks—when the broader market crashes, they often hold up relatively well. Plus, Thailand’s aging population trend is clear, and the demand for healthcare services will only keep increasing.

I’ve noticed that hospital stocks are roughly split into two ways of playing them. One is large hospital chains like BDMS and BH, mainly attracting foreign patients, especially high-end medical tourism customers. BDMS has the largest market value, reaching 3,194 billion THB, with a stock price of 20 baht, a P/E close to 20, and an ROE of 16.8%. The advantage of this kind of hospital is a strong brand and good internationalization, but the risk is that they’re relatively sensitive to exchange rate fluctuations and international economic changes.

BH is even more extreme—foreign patients account for a particularly high share, with a market value of 135 billion, a stock price of 167.5 baht, and an ROE as high as 31.9%. That number is quite appealing, but it also means that if international patient traffic declines, their performance will be hit noticeably.

The other category is smaller and mid-sized hospitals like CHG, VIBHA, and PR9, which mainly serve local patients and the insurance market. The stock prices of CHG and VIBHA are both no higher than 2 baht, and their market caps are relatively small as well, but these hospitals’ advantage is that their risk is more diversified—they don’t rely too heavily on international markets. VIBHA is viewed favorably by analysts this year, with a target price of 2.74 baht, driven by optimization of social insurance policies and expansion into new businesses.

If you ask me to choose, it depends on your investment style. If you’re looking for stable cash flow, you can consider RAM or CHG—these are hospitals that have been deeply rooted in specific regions for many years and have a steady base of patients. If you want higher growth potential, you can focus on expanding hospitals, such as PR9’s investments in digital platforms, or VIBHA’s expansion of new businesses.

On financial metrics, you should pay special attention to P/E and ROE. A P/E that’s too high means the valuation is already expensive; most companies in this sector trade around 19–20x, and only RAM is relatively higher (33x), so you should be cautious. ROE reflects how efficiently a hospital uses shareholders’ money to generate profit. BH’s 31.9% is especially high, while VIBHA and CHG are relatively lower—this also reflects differences in operating efficiency among different hospitals.

One more important point—look at the hospital’s revenue structure. Some hospitals mainly rely on foreign patients (BH, BDMS), some rely more on domestic patients and social insurance (BCH, CHG), and some operate with a mixed model (PR9). This determines how sensitive they are to different economic environments.

To be honest, the advantage of hospital stocks is that they’re easy to understand—the business models are simple and clear, unlike tech stocks, which can be much more complex. The downside is that their growth potential is limited unless a hospital can successfully expand or enter new markets. So this kind of stock is more suitable for long-term holding, acting as a stabilizer in an investment portfolio. If you’re also looking at hospital stocks, I suggest you first figure out whether you want stable cash flow or growth, and then choose based on the specific characteristics of each hospital.
