I think the most common one is gold. Because of its stability and scarce output, gold is often used as the world's common currency and is often used by Wall Street elites for speculation. Whether the price of gold plummets or the price of gold soars, I think those elites will always benefit the most.
A few years ago, the price of gold plummeted, which triggered the crazy buying fever of Chinese aunts. The word "Chinese aunt" was introduced into the Oxford dictionary, which shows its far-reaching influence. I think, if gold does not exist because of its particularity as a monetary means, it is estimated that no one will care too much about its rise and fall!
And the most important house for us young people. The rising house price has brought great influence to people's lives, and the house has become one of the necessary conditions for young people to get married.
I remember when I graduated from college, the house price was still expensive, ten years apart, and now the average price has reached 10 thousand. As a commodity, there are many real estate speculators in this abnormal price surge, and real estate buyers play a role in fueling the situation behind the scenes.
The rising level of prices is not proportional to the rising level of people's consumption power, which in my opinion belongs to speculation. Manipulating house prices behind the scenes can be said to have ruined poor young people and enriched a few rich people. I think this is one of the reasons why the rich are richer and the poor are poorer.
There are also some common agricultural products in life, which are also the targets of many people's hype. For example, in recent years, I have often heard that "garlic is cruel to you" and "ginger is your army", and garlic and Jiang Ye are often used for hype. Garlic and ginger are essential condiments in the kitchen life of every household. Although they are rarely used, they are essential. Food is the most important thing for the people, and no one can live without food, clothing, housing and transportation. I think this may be the reason why traders often speculate.
Once, if I was interviewed by a futures company, I worked as an intern for a few days. That company specializes in fried mustard tuber. The equipment in the company is dozens of computers, so everyone should buy high-end computers or low-end computers. Infer the price trend according to the horizontal fluctuation curve. Although the company can't see the shadow of mustard tuber, enterprises rely on it for profit.
There is also a big futures market in Henan, which can control the fluctuation of vegetable prices. Some people hoard a lot of goods, creating the illusion of market shortage. It seems that the market demand exceeds the market supply. When the price of vegetables goes up, they sell them.
This kind of behavior, I think it is the vegetable farmers who ultimately suffer. Because consumers can choose not to buy or buy less because the price of vegetables is too high, but vegetable farmers need to buy in large quantities. Once unsalable, you can only admit that you are unlucky.
The above are the common commodities used for "speculation" in our lives, but there are still many in reality. As long as there is demand in the market, it can be used for "speculation". Of course, there are some that can be used for hype even if there is no demand. Like bitcoin, it was fired alive.
