FRANKFURT, Feb 11 (Reuters) - European shares fell on Monday, led by financials such as Societe Generale <SOGN.PA> and Fortis <FOR.AS>, as credit spreads widened and investors fretted about the impact of a credit crunch on growth and earnings.
In the United States, AIG <AIG.N>, the world's largest insurer, disclosed that auditors had questioned the company's internal controls over its valuation of derivatives.
AIG shares fell 11.5 percent, and a Wall Street insurance index <.GSPINSE> was down more than 5 percent when Europe's stock markets closed.
European credit derivatives index spreads <ITCRS5EA=GFI> hit record highs, driven in part by worries over the structured investment vehicle (SIV) sector and the problems at AIG.
"Spreads are widening again in credit markets, and that means the market anticipates a very gloomy scenario," said Romain Boscher, head of equity management at Groupama Asset Management, in Paris.
The DJ Stoxx European insurance stocks' index <.SXIP> fell 2.7 percent, and the bank sector index <.SX7P> shed 2.1 percent.
The FTSEurofirst 300 <
> index of top European shares closed 0.9 percent lower at 1,290.9 points.It dropped 3.7 percent last week on fears of a U.S. recession and worries that financial institutions had not yet revealed the full impact of the credit crisis on their books.
"The persistently high volatility is clear evidence of the uncertainty many investors feel about (corporate) earnings and growth prospects," Commerzbank said in an equity strategy note.
But some buy-side strategists said the worst might be over in a couple of months.
Helmut Knestel, co-head of portfolio management at independent wealth managers GECAM, said one positive sign was that the across-the-board dumping of equities observed in January -- driven, he said, by hedge funds and Societe Generale -- appeared to be coming to an end.
"We expect that the technical selling triggered by big investors faced with maturing credits will be over in one or two months," Knestel said in a note.
SUMMER RECOVERY?
Ad van Tiggelen, senior strategist at ING Investment Management, linked a possible equity market recovery to the timing of the onset of a U.S. recession.
"Normally, corporate profits bottom out around 12 months after the start of a recession. Markets tend to discount this development about four to six months in advance. This means that a recovery could set in this summer, while profits would sink to their lowest level towards the start of 2009," he said in a note.
Societe Generale, the French bank reeling from a massive rogue trading scandal, fell 4 percent after it announced a rights issue at a steep discount that analysts said would dilute earnings more than expected. "The size of the discount suggests that the challenging market environment for banks has been taken into consideration," Barclays Wealth said in a note.
Volume in SocGen, at 9.24 million shares traded, was close to double the daily average over the past 90 sessions, according to Reuters data.
Bear Stearns reduced its 2008 earnings per share (EPS) estimate for Societe Generale to 7.81 euros from 9.34 euros and its 2009 EPS estimate to 8.30 euros from 9.89 euros, "to take account of the new shares in issue and a more conservative assessment of the prospects for investment banking revenues".
Elsewhere in the sector, Dutch-Belgian financial services group Fortis <FOR.BR><FOR.AS> fell 3.9 percent, UK banks HBOS <HBOS.L> and HSBC <HSBA.L> dropped 3.3 percent each, and Swiss bank UBS <UBSN.VX> lost 3.1 percent.
Drugs maker GlaxoSmithKline <GSK.L> was the top blue-chip gainer, with a rise of 1.3 percent, after UBS upgraded it to "buy" from "neutral", saying the sell-off sparked by Glaxo's disappointing 2008 guidance was overdone and a sum-of-the-parts valuation implied that the pharma division was trading at a 30 percent discount to European rivals.
Other defensives such as telecoms operator France Telecom <FTE.PA>, up 1 percent, and utility Suez <LYOE.PA>, up 0.7 percent, also found favour among risk-averse investors. (Additional reporting by Amanda Cooper and Raissa Kasolowsky in London and Blaise Robinson in Paris, editing by Will Waterman)
