#分享美股交易赢英伟达股票 The essence of current trading is buying low and selling high.

This statement sounds correct at first glance, but upon closer inspection, it makes no sense.
What exactly is the standard for "high"?
And what is the standard for "low"?
Moreover, the very concept itself is wrong.
Buying low is useful in a vegetable market or supermarket—if you see discounted fruits, discounted vegetables, or half-price toilet paper, you should indeed buy more.
But in the trading market, you absolutely cannot think this way.
This is different from supermarkets and vegetable markets.
In the market, high prices are for a reason, and low prices are for a reason too.
High and expensive prices are because it’s good, so we should chase after them and buy.
Low and cheap prices are because it’s not good, and we shouldn’t buy just because it’s cheap to bottom out.
In the market, the probability of profiting from cheap things is very small, so you shouldn’t view the trading market with normal everyday thinking.
