Dear fellow investors,

Newton's First Law of Motion

Newton's First Law of Motion states that an object in motion tends to stay in motion unless an external force acts upon it.

In the year 2022, we have been reminded how efficiently the stock market facilitates moving money from impatient people to patient people. A bull market in stocks tends to stay in motion unless an external force acts upon it. In this case, the external force is the price of money. Two-year Treasury bond rates have soared in the last 18 months as seen below:

Warren Buffett explained in his 1999 Allen and Co. talk how the price of money rising nullified the benefit of owning common stocks from 1964-1981. He then went on to explain the huge bullish price movement from 1981-1998 as being heavily affected by the consistent decline in interest rates. The lower interest rates served as a wind in the sails of common stock ownership. Economic growth from 1964-1981 was 4.3% and from 1981-1998 it was 2.7% on average. This is a good corollary to our view that increased rates help Main Street but not Wall Street.

Newton's Second Law of Motion

Newton's Second Law of Motion states that when a force acts on an object, it will cause the object to accelerate. The larger the mass of the object, the greater the force will need to be to cause it to accelerate. This law may be written as force = mass x acceleration.
