For example, the price of a commodity is 100 yuan, the lowest price in history is 30 yuan, and then it falls to 28 yuan, which is even lower than the lowest price in history.

At this time, many people think that it is lower than the historical lowest price and should be bought. Others think that the trend should be selling down.

Whether the price of horizontal goods should be bought or sold, it can't be bought or sold unilaterally below the lowest price.

For stocks, we usually measure whether their value is undervalued. For example, the highest price of a stock is 100 yuan, which is the lowest price in history when it falls to 30 yuan, but if it is bought at the price of 28 yuan, there will be two situations. On the one hand, this stock has been reduced to junk stock. Although the stock price is lower than the historical lowest price, it still falls to a lower level, and investors bear the risk and loss. In both cases, this stock is greatly undervalued. At this time, I bought it in 28 yuan, but in fact, I often can't catch the lowest price. Mature investors will buy in batches, with their positions in 28 yuan, continue to buy when they continue to fall to 20 yuan, and continue to buy when they continue to fall to 10 yuan. As long as this buying method is not debt financing buying, even if it continues to fall, it will eventually rise as long as it is underestimated.

However, if financing is used to buy the same stock, although the price in 28 yuan is very low and the stock price is undervalued, the stock price will continue to fall. When you raise money in Man Cang, it is likely that the financing position will explode before you wait for the stock price to rise.

The same is true for futures. The reason why futures operations are more difficult than stocks is precisely because of leverage. Leverage magnifies both benefits and risks. When futures are operated with the leverage of 1: 12, the futures price falls by 10%, and the risk is unbearable. And if the stock falls 10%, or even 30%, as long as it is not borrowed money, it can wait until it rises.

Commodity futures are currently in the downward channel. If you think it is the bottom of history, don't go against the market. Sometimes the power of the trend will last. Even if it hits a record low, it may be even lower.

Different investment ideas lead to different operation results. If a stock or futures is in the downtrend channel, it is suggested to wait and see to avoid the short trend, and then intervene slightly in the observation position after stopping falling and stabilizing. If the trend is favorable to you and you think it is the bottom of history, and you are going to hold it at the bottom for a long time, then the best position should not exceed 40%, that is, if you have 654.38+10,000 yuan, you should not hold more than 40,000 yuan, and the limit should not exceed half of the position, so that even if you make a mistake, the futures price will continue to fall, and the margin in your hand can guarantee that you will not be exposed. As long as you persist, you will eventually have a chance to rise several times! Finally, good luck!
