Mexican stocks ended up 0.56 percent on Friday after zigzagging for most of the session, with building company CICSA, owned by billionaire Carlos Slim, stealing the limelight on its market debut.
Mexico's peso currency closed 0.22 percent weaker at 10.8885 per dollar.
The recently choppy IPC benchmark stock index gained 82.26 points to close at 14,903.36 points.
Despite the slight rebound, the index is down over 7 percent since setting a record high on October 3 after nearly three weeks of extremely volatile trade on what analysts have called a market consolidation.
Concerns over a possible hike in US interest rates, a move that could lure cash away from Mexican stocks as investors seek higher returns, and a mixed bag of local corporate news have been largely responsible for the index's swings.
CICSA, the building arm of conglomerate Group Carso, gained as much as 8 percent during the session after kicking off trading at 7.60 pesos per share. The stock closed at 7.98 pesos.
The company is benefiting from the "Slim factor," traders said. The entrepreneur's companies are usually among Mexico's most heavily traded stocks and tend to set the market mood on a daily basis.
CICSA "has positive growth prospects in the building sector," said Jesus Viveros, an analyst with Bursametrica Management. "It will work side by side with IDEAL, which is also owned by Slim, and that's another advantage."
Slim's infrastructure company IDEAL kicked off trading in the local market just last month.
Cellular phone operator America Movil, which accounts for about 12 percent of the IPC and also belongs to the Slim empire, closed 0.48 percent higher at 12.51 pesos. Its New York-traded shares gained 0.66 percent to $23.05.
