But Newton regretted it as soon as he sold the stock. Because in July, the share price reached 1000, almost eight times higher. So Newton decided to increase investment. But at this time, Nanhai Company has encountered operational difficulties, and the real stock price is seriously decoupled from the market price. And in the previous June, the British Parliament passed the anti-bubble company law, which imposed policy restrictions on companies such as Nanhai Company. As a result, Nanhai shares plummeted not long after, and finally fell to around 124 in February, and the total assets of Nanhai Company shrank seriously. Many investors lost their money, and Newton didn't get away, losing twenty thousand pounds!
This money is undoubtedly a huge sum for Newton. He once held a high-paying position as the director of the Royal Mint, with an annual salary of only 2,000 pounds. Afterwards, Newton lamented: "I can calculate the trajectory of celestial bodies, but it is difficult to predict people's madness."
