XBI and M2: One Variable in Assessing Where We Are In Biotech’s Correction

XBI and M2: One Variable in Assessing Where We Are In Biotech’s Correction

The biotech industry marked all-time highs in February 2021. Since then, it has fallen precipitously – first in a biotech correction for the remainder of 2021 and then in a broader market correction in the first half of 2022. Many have speculated on where we are in the correction and how much more biotech can or should recede before we reach nadir. For example, recently, our industry peers at RA Capital published an opinion piece juxtaposing the breadth and depth of this drawdown to previous drawdowns1. Additionally, some of our sell-side friends compared the theoretical capacity of Big Pharma balance sheets to the sum of development-stage biopharma enterprise values to opine on the relative value of the industries versus previous time periods. We believe both are descriptively interesting and worth review, though both fall short in explaining particulars of this correction.

At Driehaus, we anchor our understanding of the movement of markets in the concept of changing supply and demand. It sounds simple, and indeed it is in concept, but we find the mastery of the application of the concept to markets to be rare. To do so, one must conceptualize, contextualize, prioritize, and synthesize many potential perspectives into a hypothesis or hypotheses for what is upsetting the balance of supply and demand in the market. It requires mental dexterity, open-mindedness, humility, endurance, attention to detail, and an understanding of how market participants act. We believe this way of thinking can be taught but requires years of study and practice – there is no shortcut. This was Richard Driehaus’ genius and gift to us and is a cornerstone of how we think. To understand the movement of this market, we try to identify what changes there may have been in aggregate in the marketplace recently and to understand how they may change moving forward.

Ed Hyman, the founder of Evercore ISI and Head of Economic Research, published a note in early June highlighting M2’s changes since COVID began2. “M2” is a measure of monetary supply in the US economy. It includes currency and coins held by the non-bank public (“M1”) as well as savings deposits, small time deposits <$100k, and shares in retail money market mutual funds. The St. Louis Fed publishes M2 monthly, going back to the 1960s. For much of the last 60+ years, the M2 grew year-over-year in a range between 3-10%. However, since COVID hit in the beginning of 2020, the government grew the money supply at historically unprecedented levels (see all time M2 chart below in Figure 1 below).

In his note, Ed Hyman juxtaposed M2 to the consumer price index (CPI) to illustrate the relationship between the two and to hypothesize that, as M2 recedes back to historical levels, the CPI and thus inflation are likely to recede as well.

We were intrigued by Ed’s analysis and wondered if there was a similar relationship between M2 and other asset prices – namely, biotech ETF prices. Thus, we plotted the year-over-year change in M2 and the monthly price of the SPDR S&P Biotech ETF XBI, hypothesizing that XBI would to some extent correlate to M2. We found that there was a notable correlation of 0.47 that modestly strengthened as we viewed XBI prices on a lag (see Figure 2 below).

For us, this analysis proffers an imperfect but directional framework for thinking about where we are in this specific biotech’s drawdown. If some meaningful part of XBI’s leg up in 2020 and subsequent leg down in 2021 and 2022 can be attributed to changes in the money supply, as this analysis suggests, then as M2 growth re-enters historical ranges its influence on XBI price action is likely to recede. Of course, this does not preclude the market from experiencing other macro or industry-level shocks that may continue to tip the balance of buyers and sellers in one direction or another, making it hazardous and likely folly to call a nadir. But we are incrementally heartened based on this analysis that a headwind we have experienced over the past 14 months may be somewhat abating.
