Overruling the historical trend, the U.S. market has put up a good show so far in the month of August. In fact, a consensus carried out from 1950 to 2017 shows that August has offered positive stock returns in 37 years and negative in 31, per moneychimp.com, the average negative return being 0.27%.

But three key ETFs, SPDR S&P 500 ETF (NYSEARCA:SPY), SPDR Dow Jones Industrial Average ETF (NYSEARCA:DIA) and Invesco QQQ Trust (NASDAQ:QQQ) added 2.2%, 1.4% and 2.7% in the past month (as of Aug 24). The funds started August on a decent note, nosedived in mid-August only to spring back later in the month.

A key finding was the revival of the small-cap segment in August with iShares Russell 2000 ETF (NYSEARCA:IWM) adding about 3.8% past month. Despite a weaker dollar, small caps surprisingly bounced back from mid-August with the Russell 2000 currently trading at a record high.

Investors should note that the Fed is on track to raise rates faster as long as the U.S. economy continues to do well. Small-cap stocks are likely to do better in a rising rate environment since these are tied more to domestic activities and are thus not hurt in a rising dollar environment (which is a likely outcome).

Economic wellbeing in the domestic land is a major positive for small-cap stocks. The reading of the U.S. GDP for the second quarter of 2018 advanced at a 4.1% annual rate of growth (the best clip in nearly four years), higher than 2.2% expansion in the previous period and in line with market expectations.

The labor market is steady and retail sales have been in great shape in the United States. The tax reform is yet another boon for U.S. stocks. Corporate earnings have been in great shape as well.

Against this backdrop, let’s take a look at a few small-cap ETFs that are among the maximum gainers in the past month (as of Aug 24, 2018).
