The difference between A-shares and U.S. stocks is first of all the different trading hours.

The trading hours of US stocks are from 9: 30am to 4: 00pm EST, with no lunch break. That is, from 10:30 pm Beijing time to 5:00 am the next day, or from 9:30 pm to 4:00 am the next day (daylight saving time).

There is no price limit.

The stocks in A shares have a daily limit of 10%, which means the maximum daily limit is 10%.

However, there is no limit on the price of individual stocks in the US stock market. With the increase of risks, it also brings more opportunities.

However, if the trading price of a stock rises or falls by more than 10% within 5 minutes, it is necessary to suspend trading. If the trading price of the stock does not return to the specified "price fluctuation range" within 15 seconds, the trading will be suspended for 5 minutes.

T+0

A shares adopt the trading system of T+ 1, that is, buy today and sell tomorrow.

Us stocks adopt T+0, that is, they are sold on the same day. However, doing T+0 account assets in US stocks needs to meet certain conditions and accept corresponding supervision.

You can short.

A shares are one-way transactions. For ordinary retail investors, they can only make a profit by buying up.

The US stock market is a two-way transaction, which can be long or short. Generally speaking, many U.S. stocks with stock prices below $5 are classified as "junk stocks" and it is difficult to short. U.S. stocks with a share price higher than $5 are more liquid and easier to sell short.

But whether a stock can be sold short depends on your broker. For example, Tiger Securities I use can generally borrow stocks with good liquidity.

Real-time quotation needs to be paid

Many domestic investors are accustomed to the free real-time quotation of A-shares, thinking that US stocks are also free real-time quotations. In fact, many US stock trading software on the market are delayed by 15 minutes, and real-time quotation needs to be paid.

However, there are some exceptions. At present, some domestic U.S. stock brokers, such as Tiger Securities, are subsidized by Tiger, and you can see the real-time market of major exchanges in the United States.

Differences between taxes

In any case, stamp duty is essential for trading A shares.

For non-American citizens, the gains from buying and selling US stocks are not subject to capital gains tax.

Value investment

In A-share trading, there is more speculation. Often, a stock has no substantial positive and performance support. It only relies on concepts or funds to push up the stock price, and then it is taken over by retail investors. The result can be imagined.

American stocks pay more attention to value investment, such as Buffett, making long-term investments. Therefore, ups and downs are rare in US stocks. As long as investors look at the company, it will definitely bring good returns.

US stocks are institutional markets.

A-share is a retail market, with retail investors accounting for 70-80%, so it is easily influenced by emotions, leading to crazy inflation or panic decline.

However, after years of development, the American stock market is constantly improving its trading system. At present, there are not many individual investors, and more than 70% of them are institutional investors, so they pay more attention to the value of enterprises.

Cooperate with top companies in the world.

In the US stock market, there are almost the best companies in the world, such as Apple, Google and Coca-Cola, and of course there are top Internet companies in China, such as Alibaba, Baidu and Tencent. In other words, investing in US stocks can buy almost all the world's high-quality assets.

Investment threshold

There is no deposit threshold for opening an A-share account, but you should make sure that the amount in the account is affordable.

Generally speaking, there is a certain threshold for opening an account in US stocks. For example, the threshold of Tiger Securities is $3,000, which is similar to the initial investment of A shares.

However, it should be noted that there is no limit on the number of shares invested in US stocks, even one share, which is different from A shares.

There are three main advantages: 1. Trading time limit.

A shares can only be T+ 1, that is, they can only be sold if they are bought today and tomorrow; The U.S. stock market is a T+0 transaction, and 1 sec can be sold in the next second, not the next day.

2. Transaction direction

A shares can only go up, which means that only when stocks go up can they have a chance to make money; Us stocks can buy up and sell down, that is, as long as the stock is moving, there is a chance to make a profit regardless of the ups and downs.

3. 1 level quotation 2 level quotation

Because US stocks can T+0, US stocks provide two-level quotation function, which facilitates many intraday trading.
