NEW YORK ( ETF Expert) -- It doesn't take much for stock markets to rev up their "risk-on" engines.For instance, European leaders have offered little more than verbal promises in their desire to push equity prices higher. Meanwhile, market-watchers celebrated the Bureau of Labor Statistics Employment Report (163,000 net jobs gain) in the U.S., even though a variety of unemployment/underemployment measures degenerated in July. In truth, European leaders have yet to agree on how to keep Spain from spiraling out of control, let alone whether or not to keep handing money over to Greece. What's more, roughly the same number of people left the labor force as those who earned a new paycheck last month; that is, the labor participation rate continues to lose ground. Nevertheless, investors in the major averages -- S&P 500, Dow, Nasdaq -- are experiencing the rush of recent three-month highs. And lately, cyclical sectors from technology to materials have led the pack. So is risk really back on the equity table? At the start of 2012, the fastest flyers were the emerging markets, Europe and U.S. small caps. U.S. large caps performed well, but they were not the front-runners. It follows that if we genuinely have an environment where investors are willing to wade into the most aggressive end of the stock pool, we would see Europe and the emergers and the smaller corporations outperforming the S&P 500... like they all did in the first three months of 2012. However, the price ratio of the Vanguard MSCI Emerging Markets ( VWO) to the S&P 500 shows relative weakness for emerging markets, not relative strength.
