China has lifted a one-year ban on new stock listings, and a handful of companies are preparing to sell new stocks as early as today. The market for initial public offerings was frozen by the government in 2012 as it pushed to bring rigor and heft to a trading system seen as too risky. And, in this new year, you could hit a paywall when it comes to watching local TV news. Also, the S&P 500 went up 29 percent in the year gone by. The Nasdaq Composite rose nearly 40 percent. But this has prompted an argument that stock prices in 2013 were like cotton candy, lots of size, but not a lot of substance.
