reviewing the market impact of quantitative operations
how much is QE/QT affecting US stocks?
Latest available data: 6371314
In the past 6 months:
the size of FED balance sheet has been rising and the S&P 500 equity index has been falling ; their correlation for the period is negative and equal to -0.06 ( weak)
this suggest that the relationship between stocks and quantitative operations in the period is inconclusive.
Zooming further out, these are the longer-term correlations between bond yields and ECN balance sheet:
1-year: -0.79 (robust)
3-year: -0.93 (robust)
Max period observed in the chart: 0.83 (robust)
IntroAs anticipated in the previous page, QE/QT are part of the policy tools for the FED and they influence both markets and the economy. Here we try to assess how extensively Quantitative operations by the FED have affected US stock markets recently.
Chart guideWe can see in the chart above both the accumulated stock of assets in the FED balance sheet (shaded area) and US equities, for a graphical examination of their long-term and short-term relationship. The key point here is to find out if quantitative easing or tightening are effectively driving stock prices at the moment, to then make the right investment decisions related to our bond allocation in the portfolio.
