Divergent paths rejoin. This week’s letter revisits a correlation between movements in oil prices and the general price level. On July 10^th of last year, I noted a divergence between the change in oil inflation and price inflation. The chart graphed the change – or momentum – in oil and price inflation, not the inflation itself. Transportation is a fundamental component and cost of our economy and companies must factor in shifts in price momentum in their pricing decisions. Here’s that chart.

At the time I had thought it likely that the change in broad price inflation – the red line in the chart – would moderate toward the momentum change in oil prices, the blue line. It did. Here is a chart with the most recent data through the end of 2022.

As I was writing last July, the momentum in general price inflation had already peaked and would start declining throughout the rest of the year. Think of momentum as a strong dog on a leash. Where it pulls, general price inflation will follow. Here’s a monthly comparison of inflation and its momentum.

At just a hint that inflation was moderating, the broad market began a rally in late October but it fizzled out in early December for a few reasons. The labor market was strong despite the Fed’s interest rate hikes and market participants correctly anticipated another 0.75% rate hike. In addition, Christmas retail sales were slow, increasing the likelihood that earnings gains would decrease. The broad market has rallied 7% since the beginning of the year.

A last note for those of you who are working on taxes and reviewing your portfolio, the investment advisor Edward Jones (2023) has a nice chart titled Investment Performance Benchmarks at the bottom of the page showing the 1, 3, and 5-year returns on various asset classes within the cash, bonds, and stocks categories. Despite the 18% drop in large cap stocks last year, the five-year performance is 9%, close to the decades long averages. The tech sector lost almost 30% in value last year but its 5-year return is almost 16%. During volatile years, relatively passive investors should keep their sights on the long-term averages.
