The bull market turned four on Monday. Over the past fifty years, every bull market that reached its fourth birthday went on to reach its fifth.
The thing to watch is the cost of money. America's ten-year borrowing rate is 5.2%, the highest in years. If the government pays that, for zero risk, shares have to keep earning more to justify their price.
For your shares, nothing changes. The people who sold at the bottom four years ago locked in the loss. The people who kept buying got the 118%. Keep buying, and don't try to call the top.
This week's letter, in full:
The S&P 500 is up 118% since its October 2022 low. In pounds a UK tracker made about 83%. Why the gap, why nobody needed a fund manager, and what year five of a bull market usually looks like.
