The Dow Jones jumps 1294 points a few days ago, however, we believe that this rally is a "dead cat bounce". We have to wait for the next quarter's earnings season to see how much of our supply chain is disrupted and how much did it affect American corporations. That day, we sold some more International Business Machines (IBM), all of Bank of New York (BK), and our remaining Berkshire Hathaway Class B (BRK.B) shares. There's too many risks at this point to hold so much stocks. We are on the 11th year of our bull market. We are not sure that this bull market will be extended to 12 years. How much higher can we really go? When will it end?
