The winning streak for equity funds may not be over yet.
"Shares are at risk of hitting a speed bump in the month ahead," said Shane Oliver, head of investment strategy at AMP Capital, in a note. But he added, "Any pullback is likely to be just another bull market correction which should be seen as a buying opportunity as the broad trend in shares remains up. Valuations remain reasonable, monetary conditions are set to remain easy, and profits are likely to improve next year."
Equities may also get a seasonal boost.

"Significant fourth-quarter seasonal strength may loom globally as both U.S. and foreign stocks have historically posted their best performances late in the year," said Alec Young, global equity strategist at S&P Capital IQ, in a note.
While emerging markets have faced volatility recently on concerns that the Fed's eventual tapering moves would lead to outflows from those markets, Young noted emerging markets have historically led the fourth-quarter trend by a large margin.
The S&P 500's average monthly gain in the fourth quarter is 1.3 percent, dating back to 1945, compared with an only 0.7 percent average gain overall, while the MSCI Emerging Market Index's average monthly gain for the fourth quarter is 1.9 percent, compared with its 1.0 percent average monthly gain overall, based on data since the index's 1988 launch, Young said.
