"Global steel producers are thriving, and their stocks are hitting new highs," note Yiannis Mostrous and Roger S. Conrad, who add, "But the best is yet to come."

In the industry-leading Personal Finance, the two advisors explain, "We're still in the early stage of a truly global bull market cycle for steel, and the companies best positioned to take advantage are headed a lot higher." Here, they look at their "Iron Five."

"As is the case with other building blocks of economic growth, steel is enjoying explosive demand from the developing world. And with the world expanding as never before, steel companies are literally selling as fast as they can produce.

"In the August 2007, we highlighted five first-rate global steel producers. Since then, they've returned an average of 67.4%, versus a decline of 3.7% for the S&P 500.

"The Iron Five are five picks that we believe are ripe for even bigger gains. Like the last group, these stocks are often volatile. They're also vulnerable to the possibility of a general stock market slide and most of all to a dip in global demand growth, particularly from China.

• B. Riley initiated shares of Hancock Holding Company (NASDAQ: HBHC) with a Buy rating of $43 target as the firm believes a higher premium is warranted given the company's superior growth prospects and conservative management profile.

DOW JONES & COMPANY (NYSE: DJ)

Could it happen? Could News Corporation (NYSE: NWS) pull its offer? They could, and the fear is absolutely there. That's why the stock has fallen. For one, the Bancroft family, which controls the majority of Dow Jones' shares, hasn't formally accepted Rupert Murdoch's $5B, $60 a share offer. And no one else has come forward with a competing bid. But it does seem that both sides are moving together in the same direction. Okay, but somebody should make up their mind -- either way -- and stop fiddling around.

EXPEDIA INC (NASDAQ: EXPE), IAC/INTERACTIVECORP (NASDAQ: IACI)

Barry Diller is back at it. The chairman and CEO of IAC/InteractiveCorp, who is also chairman of the board and a senior advisor to Expedia, is working to take online travel firm Expedia private at $30 a share. Part of any deal will involve Expedia's TripAdvisor being spun off with about 400 jobs being lost in that shuffle.
