Inventory traders liked Alan Greenspan as a result of the insurance policies he pursued throughout his tenure as chair of the US Federal Reserve benefited the fairness markets. No less than that was the standard knowledge.
However did the markets replicate this narrative on days when Greenspan testified earlier than Congress? Did they have an inclination to go up as we’d anticipate, or did their efficiency contradict the narrative? And the way did the markets reply when Jerome Powell and different Fed chairs testified? What does their habits reveal about how they assessed every Fed chair?
To reply these questions, we pulled S&P 500 and MSCI market and asset class information for all dates on which the final 5 Fed chairs testified earlier than Congress and in contrast the outcomes with each each day common returns and common return volatility.
To higher isolate market sentiment round every Fed chair, we didn’t embrace Fed charge announcement days in our evaluation. The Fed had already communicated its charge choices to the general public prior to every Fed chair’s congressional look, and the market had presumably taken the choice — to hike, maintain, or scale back charges — under consideration.
So, how did the markets reply to the testimony of every Fed chair? Have been there any standouts or surprises?
Because it seems, Janet Yellen generated essentially the most optimistic returns on the times when she testified relative to the 4 different Fed chiefs. On common, the S&P 500 rose 0.20% when Yellen spoke and solely 0.08% when Greenspan testified.
On the opposite finish of the spectrum, days when Ben Bernanke or Powell testified are related to extra unfavorable inventory market efficiency. The S&P 500 returned –0.05% on common on days when Powell or Bernanke appeared earlier than Congress. In fact, Bernanke helmed the Fed in the course of the international monetary disaster (GFC) and Powell throughout a interval of resurgent inflation. So, the bearishness they evoked is probably not particularly stunning.

We see related outcomes play out throughout small-cap and worldwide equities in addition to worth and progress, with Yellen testimony days yielding higher returns than Greenspan’s. We repeated our checks over a three-day window across the Fed chairs’ congressional testimony and once more generated qualitatively related outcomes.
Bonds informed a distinctly totally different story, nevertheless. Whereas equities outperformed when Yellen testified, mounted earnings went in the wrong way, with the whole bond index returning –0.05% on days when Yellen appeared earlier than Congress.
Volatility was one other datapoint we explored, with Bernanke testimony days displaying essentially the most volatility total.

Of all of the Fed chairs, Yellen generated essentially the most optimistic inventory market reactions and the least volatility over the previous 50 years, at the same time as bond traders tended to reply negatively to her testimony.
In any other case, each Powell’s and Paul Volcker’s tenures featured a variety of rate of interest hikes in response to rising inflation. The weaker efficiency of equities on their testimony days might replicate how the markets got here to affiliate them each with greater charges.
