Koesterich, Doll Watch Corporate Revenues After Tough Week for Stocks

Koesterich said "other developed markets are faring better," particularly in Europe as concerns in Greece fade "at least temporarily" and with European earnings per share showing an average 15% increase so far this quarter. BlackRock also likes Japan, where he said the stock market is being buoyed by big Japanese institutions, especially the three largest public-sector pension plans, buying up more domestic equities. Improved earnings in Europe and those Japanese institutions' stock buying "underscore why we believe European and Japanese equities can continue to outperform U.S. stocks."

In his weekly commentary, Bob Doll, chief equity strategist for Nuveen Investments, agreed that U.S. corporate earnings have been healthy and expressed concern over revenues, which he said are "stuck in neutral." Uncertainty over global growth prospects and Fed policy may keep equities "stuck in a trading range," though the expected rise in U.S. GDP "should allow corporate earnings to improve, helping stock prices to "grind unevenly higher." Doll argues that September remains "the most likely starting point for the Fed's first rate hike," and that there won't be any "significant news" coming out of this week's FOMC meeting. He also said there appears to be improvement in the job market, noting that last week's initial jobless claims number dropped to the lowest level in 42 years.

However, Doll expressed concern over several market technicals that he said "appear stretched" specifically that the "advance/decline line and upside/downside volume have started to trend in a negative direction" in July. While admitting those technicals "may mean nothing," he said they suggest that equities are "due for a period of consolidation that may last several weeks or longer."
