Investing in Hong Kong
The same company can trade at very different prices in Hong Kong and Shanghai. That gap is the market pricing who is allowed to buy it.
Understand the H share discount and what it is telling you.
How Investing in Hong Kong works, in one picture
The same argument as the text, as a chain. Each step is what makes the next one possible.
The fee you never see
You buy at the ask and sell at the bid, so you are down the spread the instant you trade. In an illiquid stock it dwarfs any commission you thought you were avoiding.

It is the accessible route into China
For most foreign investors, Hong Kong is where Chinese companies can actually be bought, with the disclosure standards and legal framework of an international financial centre attached.

The same company, two prices
H shares in Hong Kong have often traded at a persistent discount to the identical A shares in Shanghai. Same company, same profits, same dividend. The gap exists because the two pools of buyers are different and capital cannot move freely between them.
A price gap that cannot be arbitraged away is not a free lunch. It is a fact about the plumbing.

Policy risk is imported
The listings are in Hong Kong. The businesses and the regulators are on the mainland. You get the better legal wrapper and the same underlying exposure to Beijing's decisions.

Watch the liquidity
Outside the largest names, HKEX small caps can be thinly traded, and the spread you pay to get in and out can quietly exceed the return you were hoping for.
You can explain why an H share can be permanently cheaper than the identical A share.
