No one should find this a surprising suggestion. The Bank of Japan has a long tradition of propping up the Japanese equity market with large purchases of equities. The European Central Bank purchases corporate as well as government bonds. In 1989 Fed governor Robert Heller said that as the Fed already rigs the bond market with purchases, the Fed can also rig the stock market to stop price declines. That is the reason the Plunge Protection Team (PPT) was created in 1987.
Looking at the chart of futures activity on the E-mini S&P 500, we see an uptick in activity on February 2 when the market dropped, with higher increases in future activity last Monday and Tuesday placing Tuesday’s futures activity at about four times the daily average of the previous month. Futures activity last Wednesday and Thursday remained above the average daily activity of the previous month, and Friday’s activity was about three times the previous month’s daily average. The result of this futures activity was to send the market up, because the futures activity was purchases, not sales. http://www.cmegroup.com/trading/equity-index/us-index/e-mini-sandp500_quotes_volume_voi.html
Who would be purchasing S&P equity futures when the market is collapsing from under them? The most likely answer we can come up with is that the Fed is acting for the PPT. The Fed can actually stop a market decline without purchasing a single futures contract. All that has to happen is that a trader recognized as operating for the Fed or PPT enters a futures bid just below the current price. The traders see the bid as the Fed establishing a floor below which it will not let the market fall. Expecting continuing declines to make the bid effective, they front-run the bid, and the hedge funds algorithms pick it up, and up goes the market.
Is there another explanation for the shift in the market from decline to rise? Are retail investors purchasing dips? Not according to this report in Bloomberg — https://www.bloomberg.com/news/articles/2018-02-12/record-23-billion-flees-world-s-largest-etf-as-panic-reigns — that last week a record $23.6 billion was removed from the world’s largest ETF, the SPDR S& 500 index fund. Here we see retail investors abandoning the market.
If central banks can produce zero interest rates simultaneously with a massive increase in indebtedness, why can’t they keep equity prices far above the values supported by fundamentals? As central banks have learned that they can rig financial asset prices to the delight of everyone in the market, in what sense does capitalism, free markets, and price discovery exist? Have we entered a new kind of economic system?
