"Halftime" for the 2015 investing year is here, and traders and investors galore are taking hard looks at their portfolios and positions.
With the Dow and S&P 500 both lower or flat on a year-to-date basis, the big question is whether there are enough positive catalysts to kick-start the market to the upside?
Among the major U.S. indices, only the Nasdaq Composite has shown some decent relative strength, giving it a 4 percent gain so far this year.
Strategists on Wall Street haven't changed their view on the large cap market much since the beginning of the year. The consensus view was that the S&P 500 would post mid- to high single-digit percentage gains for the year, and that thesis remains largely intact.
