Much of how the stock market functions over extended time periods depends on sentiment. There is no such thing as a risk-free investment, much less a risk-free day trade. Sentiment constantly shifts from optimism and pessimism. Both can, and usually do, go to extremes. In the past three trading sessions the percentage of stocks trading above the very short term 5 day moving average has risen dramatically approaching 80%. One can see this shift in the chart In 1958 Detroit’s Big 3 produced the most over-chromed, heaviest, most garish in design kitsch wagons that even exceeded the prior year models of the 1950s. And they sold millions of them. When one compares the 1958 versions with those of the past and the ones that followed they are unique in terms of the degree of excess.
