1. Risk hedging
Mom gave Xiao Ming 10 yuan and asked him to go to the vegetable market to buy some vegetables.
Xiao Ming thought with the money in his pocket: Mom likes to eat eggplant, but Dad doesn't. But Dad is not at home, I don't know if he will come back for dinner today? So Xiao Ming spent 3 yuan to buy eggplant, and then spent another 3 yuan to buy some broccoli that Dad likes to eat.
This is risk hedging, using broccoli to hedge the risk that Dad will come back for dinner but doesn't like to eat eggplant.
2. Arbitrage
Following the first point, Xiao Ming had 4 yuan left after buying eggplants. Seeing that a roadside stall was selling grapefruits at a special price, Xiao Ming bought a grapefruit with the remaining 4 yuan.
When going upstairs, Grandma Li looked at the grapefruit in Xiao Ming's hand and said: Wow! Your grapefruit is so fresh, where did you buy it? I can't always get the grapefruit in the supermarket downstairs, how about you sell it to me for 5 yuan?
So Xiao Ming sold the grapefruit to Grandma Li for 5 yuan. This is arbitrage, using the price difference of the same product in different markets to make a profit.
3. Gambling
There are three uncles in the village, each of whom has 10,000 yuan of spare money, but they don't know how to use it, so they play Landlord when they have nothing to do. The loser pays 1,000 yuan to the winner, and the winner can get 2,000 yuan.
4. Investment
Later, Uncle Wang felt that he was unlucky, so he bought all the remaining money for Isatis root, 1 yuan a bag, and Uncle Wang bought 5,000 bags. Later, SARS broke out, and the price of Isatis root rose to 10 yuan a bag. The uncle sold all of them directly, and each person made 45,000 yuan.
5. Selling to stop loss
The aunts saw that Isatis root was so profitable, so they spent 10,000 yuan to buy 1,000 bags of Isatis root at 10 yuan a bag, ready to sell them to make money later. Later, SARS was cured, and the price of Isatis root dropped to 5 yuan a bag. Some aunts felt something was wrong and sold all of them quickly, losing 5,000 yuan.
6. Investors who followed the trend were trapped
Another group of middle-aged women, who firmly believed that the price of Isatis root would rise, refused to sell and were eventually trapped.
