Whitney Tilson on letting winners run as market hits new highs

Whitney Tilson, editor at Stansberry Research, says the current market conditions have made him "much more prone to let my winners run," and that investors should not take a market pushing to all-time highs as some sort of sell signal because in most times -- including today -- new highs are a positive, even if they inspire some nervousness and fear of new heights. Tilson says that investors should focus less on headlines and more on what drives markets, namely a strong economy and growing corporate profits.
