Investor AB says core assets well-capitalised

* Q2 net profit rises to $2.15 bln vs year-ago loss

* CEO says worried about strength of economic recovery

STOCKHOLM, July 14 (Reuters) - Sweden's Investor AB (INVEb.ST) said on Tuesday the companies that make up its core portfolio were generally well capitalised and that the investment firm was ready to act on opportunities.

The investment vehicle of Sweden's powerful Wallenberg family has put money toward rights issues in both garden tool maker Husqvarna (HUSQb.ST) and banking group SEB (SEBa.ST) to help fortify the firms in the face of a sharp market downturn.

"As noted earlier, our core investments are generally well capitalised, after cautious dividend payouts and successful capital raisings, and rapidly adjusted cost structures to reflect tough market conditions," Chief Executive Borje Ekholm said in Investor's second-quarter earnings report.

Investor owns stakes in some of Sweden's top companies, including telecom equipment maker Ericsson (ERICb.ST), SEB, truck maker Scania (SCVb.ST) and appliances maker Electrolux (ELUXb.ST).

The holding company booked a consolidated net profit of 16.85 billion Swedish crowns ($2.15 billion) in the second quarter, compared with a year-ago loss of 3.53 billion as the value of its core investments rose on a buoyant stock market.

Ekholm said he would be surprised if the global economy wasn't bottoming out and a recovery was on the way, but visibility on the fundamental activity level in the economy was poor. "I am concerned the recovery process may not be as robust as we hope."

Investor's companies are well positioned to capture growth opportunities in the years to come, he added.

The company had a net cash position of 1.8 billion crowns at the end of June while its net asset value stood at 125.7 billion crowns compared to 115.2 at the turn of the year. (Reporting by Anna Ringstrom, editing by Will Waterman) ($1=7.855 Swedish Crown)
