Why don't I look at price fluctuations?

No matter how awesome fund companies and traders are, they are essentially using exposed positions to gamble on returns, but some fund companies, such as Warren Buffett, occupy the unimaginable time of ordinary people (you can not sell a share for 20 years) and the advantages of funds (hundreds of millions of dollars) and the market to "gamble", and there are still chips when you lose the bet, and you can resist and not play the table for a long time.

And the people in the market do not have such an advantage as Berkshire Hathaway at all, so there is only one result of "betting" in the market, that is, losing.

The only way to beat the market is to expose extremely low positions, and what can still be profitable can only be achieved by a neutral quantitative strategy that hedges away risks, such as the market-making strategy of grid + hedging.

In this field, the opportunity to make money is not uncommon, but what is really scarce is the opportunity and ability to make a profit in the long term.
