每次股災崩盤我們很常看到這類統計，例如Barron’s 3/7這篇「When Will the Stock Market Recover? The Pain Isn’t Over.」：
「1929年以來，美國股市總共發生121次單日漲跌幅超過4.2%，而65個交易日後，股市終究是漲是跌的機率跟丟硬幣沒兩樣 — 50%隨後S&P500平均下跌14.5%；50%上漲18.1%。」 （ “The data back him up. Since 1929, there have been 121 one-day moves of 4.2% or more, according to John Kolovos, chief technical market strategist at Macro Risk Advisors—and in those instances, the chances of a positive return over the following 65 trading days were no better than a coin flip. Half of the time, the S&P 500 fell with an average drop of 14.5%. The other half, the S&P 500 gained an average of 18.1%.”）
（As he once described it in a 2011 interview with LEADERS magazine, “I made my fortune by turning right when everyone else was going left. In the late ’80s and early ’90s, I was buying office buildings at 50 cents on the dollar. I kept looking over my shoulder to see who my competition was, but there was no one. I could not help but question whether I was wrong. Fear and courage are very closely related.”）
The cut to the corporate tax and deregulatory process are giving businesses more certainty and money to spend on capital investments.
However, the severer trade wars between China and America will definitely wound the economy of the both sides, particularly worse on the US . It means the benefits from tax cut and deregulation could be wiped out by the wrong tariffs. These are the macro-constraints of the U.S.
Meanwhile, according to Credit Suisse, the capital expenditures of the S&P500 have risen to $166 billion in the first quarter of 2018, up 24% from a year earlier. Is it a good news? Well, it depends on each isolated case. The capital expenditure of companies may or may not lead to good returns, which means the more capital investing activities do not promise higher profits in the future. Wastes or mis-location of resources can happen in this the-more-the-better investing phenomenon, especially when a company has some bad KPI requirements. It’s due to “Money Illusion” to a certain degree. Bad incentive systems influence the managers’ decisions as well. And I believe these two factors are the source of the business cycle.
I haven’t expected the turning point coming so fast. Nevertheless, I could smell something going wrong recently. I’ve increased the cash share of my investment pile more than fifty percentage and guess by doing so would be safer in the next two years. Of course, if there is a good objective at an attractive price, I will buy it anyway without considering the macro-economy. Such good deals can always overcome the whole investing environment.
