Steel-sector stocks have been taking investors on a roller-coaster ride lately. At one point this year, they had climbed a whopping 36%, but they are now down 16% for the year.

US steelmaker Nucor (NYSE:NUE) took a thumping along with the rest of the sector. Shares are down 18% for the year, dropping 42% from their peak for 2008.

However, Money Map Report editor Horacio Marquez reckons Nucor’s “terrific fundamentals” mean its shares are poised for big gains. He says, “all the technical indicators … point to a massively oversold condition in Nucor’s shares.”

When you have a market that’s in the process of hammering out a bottom (as I believe we have right now), my “best investing idea” involves carefully adding some of the very best small cap stocks to your portfolio.
