Billionaire investor Carl Icahn reported Monday he has taken new investments in toy maker Mattel Inc. (MAT) and building-products maker Masco Corp. (MAS).

Icahn, known for his activist stances and battles with boards, said in a filing with the Securities and Exchange Commission that he built up a stake of 5.02 million shares in Mattel and 2.43 million shares in Masco, two bets that lean on the U.S. consumer spending money.

But at the same time, he reported no stakes as of Sept. 30 in two of his more high-profile holdings, fast-food chain Wendy's/Arby's Group Inc. (WEN) and Yahoo Inc. (YHOO). Yahoo had been the recipient of Icahn activism in 2008, but once the Internet giant switched chief executives, he said he was content to pare his stake back.

Last period, Icahn reported growing energy holdings, and he again added to his holdings of oil and natural gas producer Chesapeake Energy Inc. (CHK), boosting the stake to 16.64 million shares, from 12.74 million at the end of June. But Icahn also reported no stakes in Anadarko Petroleum Corp. (APC) or Ensco PLC (ESV), two companies he reported new stakes in last period.

Among his other new holdings as of the end of September were Commercial Metals Co. (CMC), with 2.46 million shares, and Motricity Inc. (MOTR), at 4.4 million shares. Icahn's son Brett Icahn recently joined the board of the mobile Internet company Motricity and the two previously were reported to have discussed it as an investment.

He also continued to boost his share of Lawson Software Inc. (LWSN), which rose to 16.5 million shares, from 9.5 million last period.

Investors who manage more than $100 million are often required to disclose their holdings within a month and a half of the end of every quarter. Icahn and others are sometimes given the ability to keep some investments confidential. The filing indicated some of his current holdings are in fact kept confidential.

The billionaire has been in the middle of many high-profile board exchanges, and has been making waves the past few weeks trying to stop private-equity firm Blackstone Group LP's (BX) bid for energy company Dynegy Inc. (DYN). Icahn revealed last week his stake in Dynegy had risen to 12.9%, or 15.6 million shares, and reiterated earlier Monday he intends to vote against the deal.

He also has been active in his holdings in Lions Gate Entertainment Corp. (LGF), where he now holds 44.6 million shares in total, plus about $2 million in debt. He has had an outstanding, long-running tender offer for all remaining shares of the film studio. The studio, in turn, has sued Icahn.

Icahn has also been increasing his stake in Motorola Inc. (MOT), which he disclosed earlier this month was at 265.6 million shares, a stake that's growing in front of a split of Motorola's business, which Icahn has said he expects to improve its value.

Last week, Icahn also revealed he had increased his holdings in Hain Celestial Group Inc. (HAIN), which currently sits at 6.39 million shares. An increased stake in Mentor Graphics Corp. (MENT) had also already been reported by Icahn.

Icahn reported little to no change to his holdings in biotechnology stocks, including a steady stake in Amylin Pharmaceuticals Inc. (AMLN), a drug maker that saw shares tumble 35% in the aftermath of a setback in its diabetes treatment.

His holdings in Genzyme Corp. (GENZ) remained at 13.1 million shares as the drug maker finds itself in a fight with French pharmaceutical giant Sanofi-Aventis SA (SNY) which is now pushing a hostile takeover attempt. Icahn has two representatives on Genzyme's board.
