UK stock closing: Britain's leading shares fell on Monday after touching a 4-1/2 year high early in the session, with technical analysts noting the index could be set for a minor correction.
Energy stocks, among Friday's biggest gainers, were the main drag on blue-chip sentiment as Nomura warned that the sector was inexpensive for a reason and attractive price-to-earnings or dividend yields masked high break-even oil prices.
"If headline production continues to be used as a proxy for cash flow for European Big Oil, we see no positive inflection point during 1H 2013," Nomura said in a note.
At the close, the FTSE 100 was down 13.72 points, or 0.2 percent at 6,107.86, having gained more than 2 percent since the start of 2013.

Weekly inflows into equity funds hit a five-year high in the first full week of January, according to EPFR Global, with European equity funds enjoying brisk inflows as support for the financial system from central banks, an easing of euro zone debt risks and a U.S. budget deal fuelled appetite for equities.
Schroders was a strong performer, up 2.7 percent, with traders saying the stock was also lifted by an upgrade to "overweight" by HSBC in an asset management review.
HSBC downgraded its rating for Aberdeen Asset Management to "neutral", but the shares gained 1.5 percent, buoyed by the fund flow data and more positive comment from JP Morgan Chase, which raised its
