NYSE Euronext (NYX) acquired American Stock Exchange (Amex) in 2008 to expand its equities, options and exchange-traded funds (ETFs) trading business. Recently NYSE announced plans to sell the majority of its stake in the Amex stock options market to seven companies -- including top banks, trading houses and brokerages. With this move, the company hopes to increase its trading volumes by giving major brokerages an incentive to bring their business to Amex. Major competitors are Nasdaq OMX (NDAQ), CME Group (CME), BATS Global and Direct Edge.

NYSE Euronext (NYX) and Deutsche Boerse AG of Germany recently announced a merger that will create the world's largest financial exchange. NYSE is the world's largest stock exchange in the world by market capitalization of its listed companies and Deutsche Boerse AG is the largest stock exchange operator in Germany. NYSE Euronext's main competitors are Nasdaq OMX (NDAQ) and CME Group (CME).

We have a price estimate of $34.77 for NYSE Euronext's stock, which stands below market price.

There's been no shortage of new highs on the New York Stock Exchange lately -- but the thing is, very few of those new highs have been actual common stocks. Instead, a glut of preferred stocks and various fixed-income securities have been artificially inflating the annual-high figures on the Big Board.

Against this backdrop, it's even more impressive that Silver Wheaton (SLW) tapped the latest in a string of new annual highs today. The stock cruised up to $22.84 earlier, marking an all-time peak for the U.S.-traded shares of the Canadian commodity concern.

General Growth Properties (GGWPQ), the mall operator that shuffled into bankruptcy protection last year, says it has applied to list its shares on the New York Stock Exchange (NYSE) once again. The company hopes to begin trading on the Big Board as of March 5, using its previous ticker of GGP.

"Trading again on the NYSE will mark an important milestone in GGP's restructuring process," said CEO Adam Metz in a press release. The shares currently trade over the counter.

The future investment stars are already with us. The NYSE Financial Future Challenge, operated by the NYSE Foundation, By Kids for Kids, K12 Inc. and the United Investors Association, is in full swing, with five finalists just identified. To reach this level, the participants had to develop a new product, idea or process that would "excite, educate and motivate their peers" to become interested in the financial marketplace. The eventual winner lurks within this subset and will receive a $2,500 prize -- a great way to get that portfolio started. And, he or she will be feted at a closing bell ceremony at the NYSE (NYX) on January 11, 2010.

The finalists presented a variety of ideas which are sure to generate some buzz. Kelsey Foss, a 12-year-old from Mountainville, NY, proposed a new television show, "Stock Market Tycoon Idol," which would harness the popularity of reality TV while amping up the content. The program would involve the journeys of 10 kids as they seek to make money or lose it, with the possibility of becoming virtual millionaires along the way. The show would be set at a mock NYSE studio on Wall Street, and exports would be brought out to mentor the contestants. The reality TV reach would help engage a younger audience.

The IPO market has been pretty slow for the past two years due to the effects of a subprime mortgage crisis that turned into a credit crisis that turned into a worldwide financial crisis and recession. Nonetheless, two companies made their debuts Thursday -- one on the NYSE (NYSE: NYX), the other on the NASDAQ -- and they nailed it. Hyatt Hotels (NYSE: H) gave its investors a 12% gain on its first Big Board trading day, and Ancestry.com (NASDAQ: ACOM) switched those digits, jumping 21% in its first day of trading.

Hyatt Hotels overcame two major concerns. The worldwide travel market slump has been tough on hotel companies, and Hyatt has been subject to the same forces as everyone else. Also, investors may have been worried about infighting among the founder's heirs (the Pritzker family), but the double-digit price increase suggests that investors don't foresee Bancroft-style squabbles screwing investors -- or, if you don't like Dow Jones, now a part of News Corp (NASDAQ: NWS), Playboy (NYSE: PLA) makes the same point.

When the market started to crap the bed last year, hundreds of public companies were faced with the prospect of delisting due to their low share prices and market caps.

Because of the unusual nature of the circumstances -- and the fact that they had much bigger problems to devote resources to -- the NYSE and Nasdaq elected not to enforce minimum share price requirements temporarily. But now that the market has rallied, what about companies that haven't been able to get their share prices back up a bit?

What's new? Well, trading on the NYSE is sluggish. In fact it's the slowest in two decades. Now, some of this is normal. Brokers often take vacations in July and August. Those who can do so rush out to the Hamptons or Long Island.

But this year is notably slow. Investors are busy digesting second quarter earnings and trying to figure out what to do next. The Dow did reach the 9,000 mark this week, though. We've seen a 44% rally off the March 9 lows, according to data compiled by Bloomberg, the steepest since the 1930s.

With listed stocks getting knocked around, the New York Stock Exchange is considering extending temporary relief from listing requirements. Once a company is dropped from the exchange, it runs risks ranging from market cap loss to limited liquidity. But NYSE Euronext (NYSE: NYX) CEO Duncan Niederauer was clear that the moves are not permanent. For now, the goal remains to protect companies that are at risk of being delisted. This comes after the S&P 500 fell 38% last year -- its worst performance since 1937.

The two rules that have been relaxed are the maintenance of a share price of at least $1 and a market cap of at least $15 million. The return of both measures was delayed back in April. Currently, 31 companies on the NYSE are at risk, including Blockbuster Inc. (NYSE: BBI) and Lear Corp (NYSE: LEA).
