LONDON, Nov 5 (Reuters) - European stocks edged lower in cautious trade on Monday as investors opted for safer havens ahead of a too-close-to-call presidential election in the United States this week.
By 0835 GMT, the FTSEurofirst 300 shed 5.93 points, or 0.5 percent, to 1,109.26, with investors hedging their bets after the index rose 1.6 percent last week, nearing the top of its recent trading range around 1,120.

That knocked peer TNT Express which shed 3.1 percent. TNT recently announced a 12 percent fall in quarterly profit.
Some 48 percent of European companies have missed profit expectations so far in the third-quarter, lagging a far better performance from U.S. peers.
The index's top gainers were those companies that offered some light for investors at the end of a gloomy earnings tunnel.
A 10 percent jump in first-half profit and raised guidance propelled Irish low cost airline Ryanair 9 percent higher, helping lift peer Easyjet and the broader travel and leisure sector.
Weir climbed 4.2 percent after the firm assuaged concerns over the outlook for engineers by saying it was on track to meet expectations for the full year.
Despite nearly half the companies that have so far reported in Q3 missing expectations, analysts have increased fourth-quarter estimates by around 1 percent for those corporates.
But broader maket moves continue to be dominated by macro themes, adding to investor uncertainty.
As well as the U.S. presidential election there is once-a-decade power transfer in China, and Greece's attempt to gain political support for measures to obtain further aid.
