"People are understandably worried when the stock market hits a new high," she said. But "in the past, when the market has reached a [record] it continued to move higher for an average of 21 months."
That isn't to say there won't be some short-term interruptions in the upward trajectory.
"There still is going to be volatility, and investors can expect there will be corrections along the way," she said, noting that historically stocks have risen over time despite such fluctuations.
Warne said investors should have a mix of stocks and bonds within their portfolios, but that the percentages of those holdings depends upon the investor's age and goals.
Rates on short-term investments, which are driven by the Federal Reserve, can't go much lower. But Warne said she anticipates that interest rates on longer-term investments eventually will move higher and that a laddered bond portfolio of different maturities could be used to boost returns.
Warne said she prefers the shares of companies with good growth opportunities, such as those that are entering new markets. And she likes companies that pay dividends, particularly those that have a track record of raising payouts over time.
She singled out Qualcomm, Pfizer and Chevron.
She likes Qualcomm because it owns the patents on the technology that is used in all smartphones.
She likes Pfizer because it spun off its non-core operations its animal business to refocus on biopharmaceuticals.
And she likes Chevron because it is "moving forward and growing."
Warne said she anticipates the economy will continue to grow modestly this year, and despite the relatively slow growth will be capable of producing good investment results.
