You've been a moron if you've been waiting for revenue to pick up before you've bought. You have been a fool if you've feared the Federal Reserve would act imminently. You've been a total bozo if you've listened to President Obama about the crashing of the economy because of the sequester -- particularly if you've sold the defense names, which have been the best-acting stocks in the book. In fact, the moves are eerie. It is as if there had been an edict that every stock -- other than gold stocks, a copper or an iron ore stock and maybe a few steels -- that everything has to go higher. To me this speaks directly to the notion of underinvestment and the supply and demand of equities. For years and years now, companies have been taking in supply. Other than the equity sells mandated by the Troubled Asset Relief Program and the endless master limited partnerships, very little stock has been issued. One year after Facebook ( FB), and the only two initial public offerings of any real size have been Pinnacle Foods ( PF), a $3 billion company and Quintiles TransNational ( Q), about a $6 billion company. Plus, it isn't as if we have had a lot of stock-for-stock deals that have seen a flood of new equity from mergers and acquisitions -- hardly. The very few deals we've gotten have tended to be cash-related. Meanwhile, the share retirement is out of control. While this market has simmered for the past three years, a huge amount of stock has vanished. Procter & Gamble ( PG) has gone from 2.9 billion shares to 2.74 billion; CBS ( CBS) has shrunk from 694 million to 638 million; Time Warner ( TWX) had 1.145 billion and now has 950 million; Intel ( INTC) went from 5.5 billion to 4.9 billion; Pfizer ( PFE), at 8 billion, is now down to 7.2 billion; Wal-Mart ( WMT) went from 3.87 billion to 3.3 billion; and Exxon Mobil ( XOM) went from 4.8 billion to 4.48 billion. Even growth stocks like Celgene ( CELG) have taken down their share count. Celgene's has fallen from 469 million to 432 million.
