Perhaps monopolies are part > and parcel of bull markets and bull markets denoument > It has been the case through the century that the major indices have been supported by about a dozen stocks. Currently, the NASDAQ is supported by 8 stocks, the DJIA 5. There are about 6,000 stocks listed on the US exchanges. Most have not gained in value in the past two years, or so-and many have lost value, (re: Russell 2000 and Value Line vs. DJIA and NASDAQ.) About 80% of the century's index gains have occurred in only 20 of the century's years. In all of the 20 years, there was a MS type of "monopoly," (eg., AT&T, and later IBM, and earlier, RCA, all of which had the DOJ's attention for AT.) But there were companies that were supporting the indices that were NOT "monopolies," too, in all cases. Most of the companies supporting the indices were not "monopolies." The current bull market is starting its ninth year. The chances of a bull market lasting at least nine years is about 30%, (and that is the chances of it continuing, BTW.) If it makes it through this year, then it will be the longest bull market run of the century, (4.3 years being the average.) By contrast, the chances of a bear market like the one that lasted from 1930-1955 is small, (about 20%,) but it was a virtual certainty that it would happen at least once in the century. The chances that the markets would loose 90% of their value, (like they did in the 14 months of 1930 and early 1931,) is finite, but very rare-about a 4.43 sigma chance, or it would be expected, on average, every 841 years. In the century, there have 54 declines in market value of more than 10%, 15 of which were more than 25%. (All stats assume a fractal dimension of 2, ie., the EMH.)
