Very interesting Nick. Have you analysed the indicies following rate cuts over a greater timespan?
Macroeconomically, the chart makes sense - the fed is cutting rates as it gets evidence of a slowing economy. The statistics it uses to make that assessment come out more frequently than company profits and with the impact of inventories, many companies can sustain production in the face of falling sales resulting in a time lag.
What would be more interesting is a longer term analysis looking at the typical length/depth of the contraction following the start of rate cuts.
Was discussed here;
During the last Fed easing cycle they cut 500 bps in 2 and a half years and the S&P500 fell 50% over the same period, however every time is different, 1990-91 saw much less carnage in the stock market.
