Stocks are issued and circulated in the stock market. The stock market can also be said to refer to the site where given stocks are traded and transferred.

Stock trading is realized through the stock market. Generally, the stock market can be divided into primary and secondary markets. The primary market is also called the stock issuance market, and the secondary market is also called the stock exchange market.

In addition to stocks, securities also include state bonds, enterprise bonds, real estate mortgage bonds, etc. State bonds appeared earlier and were the first marketable bonds to be traded. With the development of the commodity economy, securities such as stocks gradually emerged.

Therefore, stock trading is only a component of bond trading, and the stock market is only one of a variety of bond markets. At present, there are few single stock markets.

The stock market is one of the critical ways for listed enterprises to raise funds. With the development of the commodity economy, enterprises are becoming larger and larger, which requires a large amount of long-term capital. However, it is challenging to meet the demand for production progress by relying solely on the enterprise's own capitalization accumulation, so it is necessary to raise funds from outside. There are generally three ways for enterprises to raise long-term capital: first, borrowing from banks; second is to issuing corporate bonds; The third is to issuing shares. The first two methods have higher interest rates and time constraints, which not only increase the operating costs of enterprises but also make it difficult to stabilize the capital of enterprises, so they have significant limitations. However, to raise funds by issuing shares, it is not necessary to repay the principal and interest but only to allocate part of the profits to pay dividends. Comparing these three financing methods, the way of issuing shares is undoubtedly the most economical and beneficial for enterprises.

Therefore, issuing stocks to raise capital has become an essential form of developing the economy of large enterprises, and stock trading plays a significant role in the whole securities trading.

The changes in the stock market are closely related to the progress of the whole market economy. The stock market has always played a role as a barometer of economic conditions in the market economy.

The reliable P2P of the guarantor and the P2P risk of the acceptance bill as collateral is not high, so long as the above evaluation is based on the current situation of the whole industry. In addition, P2P is very sensitive to the cyclical fluctuations of the economy (because it can not pass the bank risk control financing). Once the economy has a significant problem, the possibility of large-scale default of the guarantee company must be considered.

Other equities and debt investments require considerable experience. Foreign exchange and precious metal investment require professional judgment on the macro level, which makes it more difficult to make profits. The small plate of commodity trading and investment is darker than the stock market ten years ago.
