Surfing
Equipment requires at least a board, the wind needs to be strong, and the waves need to be big (swells are a collection of waves but different; tides are influenced by the moon's gravity, and most of the three have it but in different proportions).
Kite surfing can also be considered one of them; the waves may not be big enough, but the wind needs to be strong. It reduces the investment difficulty.
Sailing
It can be seen as kite surfing with a very short line; personally, I feel it is more difficult than kite surfing. The wind is stronger at higher altitudes, and the direction can be more chaotic. Sometimes the kite may fall, but fortunately, there is height. If there is no wind during the descent, you can still move, reel in the line, or do both, and there may be a chance to relaunch. Sailing sometimes requires swaying and shaking operations.
Diving
No matter how high the waves above, it doesn't matter, as long as the price is low enough and there is enough oxygen (the cabin is not too high).
There are many divers, whether they are real divers, those in declining forums, or the majority who remain silent online, or in reality.
They are all people who can endure loneliness and remain calm. But there are also those who suffocate, waiting for an accident to happen.
Policy, funding, emotions, fundamentals, news
How should these be ranked in terms of their impact on the stock market, from largest to smallest? Technical analysis will not be discussed for now.
This question made me realize a principle.
Suppose you have two accounts, A and B, and you bought the same stock. Account A bought in at 3 yuan, while Account B bought in at 8 yuan. Currently, the stock price is 5 yuan, and you urgently need money. Which account would be more cost-effective to sell from?
