Should I buy BABA JD and TCEHY on the American market or the Chinese market?

I buy BABA and TCEHY on the US market because my broker Firstrade has $0 commissions compared to if I use FSMone or Tiger Brokers.

US elections are known to be one of the most volatile periods for the stock market meaning you can take advantage of the price declines if you are a investor for the long term.

Personally, I think Tencent is currently still undervalued as most people are ignoring how powerful its network effect and the vast amount of economic moat the company has. It is practically impregnable and a modern day Berkshire Hathaway with solid balance sheet and long term growth prospects. I would be glad to buy more if the company were to have a pullback in stock prices near my intrinsic valuation.

As for Alibaba, it is also undervalued if you compare it to its western counterpart (Amazon). I bought it around $260 level to take advantage of the lowered price entry point before Ant Financial's IPO. Currently the stock is in alot of positive light and senitments which drove stock prices past $300 and I believe there are still room for growth since it owns 30% of Ant Group (previously Alipay).

JD also has tremendous potential but there are just way too many E commerce stocks (Company) that also has growth potential. I can just list out a few such as Etsy, Mercado Libre etc.

At the end of the day, do your own due diligence so you won't be taken advantage of. Looking at stock prices will not tell you anything at all. So do your research and proper due diligence before you committ to any investments.

Hope this helps!

Both are fine, the shares avaliable on the US markets are heavily bought by large firms and prominent individuals in US, the trade war tensions are unlikely to delist these shares from the US markets.

Do note of the minimum lot size in Chinese markets.
