Noteworthy this week

  • Thailand and Korea hit by rising oil prices
  • Some Asian markets have very low oil reserves
  • Hormuz isn’t just about oil
  • Oil prices above US$100/bbl correct themselves
  • BYD sees massive sales drop

Thailand and Korea hit by rising oil prices: In Asia, Thailand and South Korea have the highest GDP exposure to imported oil, so the volatility in their markets reflects fears about how that will play out.

Some Asian markets have very low oil reserves: Across Asia, reserves range from more than 250 days in some countries to just a few weeks in others.

Hormuz isn’t just about oil: It’s a chokepoint for fertilizer inputs. Energy shock → fertilizer shock → food shock.

Oil prices above US$100/bbl correct themselves: The relationship between oil prices and production costs is endogenous, in that higher prices incentivize drilling higher-cost wells. Oil prices above US$100/bbl would incentivize so much new production that prices would eventually fall back.

BYD sees massive sales drop: BYD is currently running at below 50% capacity, and sales dropped 36% on a apples-to-apples basis.

Readings this week

The Concentration Game: Understanding Portfolio Effects of U.S. Equity Market Concentration

“In recent years, breakthroughs in tech and artificial intelligence have helped drive notably strong performance in a handful of mega cap stocks. This increase in equity market concentration has coincided with a decline in the risk‑adjusted performance of many actively managed portfolios.

To understand this dynamic, we consider the impact of concentration on overall equity portfolio risk and the potential to generate positive active returns. While concentration can challenge common approaches to managing risk and producing alpha, understanding concentration’s underlying drivers may allow investors to adjust their processes to better account for its effects.”
