Despite daily volatility in broader markets, a large number of US equities had another strong month in June. For instance, SPDR S&P 500 (NYSE:SPY) which tracks the S&P 500 Index was up 1.4% in June. Similarly, Invesco QQQ Trust (NASDAQ:QQQ) that tracks the NASDAQ 100 Index returned 6.2% in June. However, the SPDR Dow Jones Industrial Average ETF Trust (NYSE:DIA) that tracks the Dow Jones Industrial Average was down 1.6% in June. Today's article introduces a number of exchange-traded funds (ETFs) that had robust returns last month. It also highlights several that did not have a good month. Winners tend to momentum for several weeks if not months. Therefore, a number of the winner funds of June are likely to do well in July, too. And those that did not fare well last month could begin to stabilize, offering better entry points for buy-and-hold investors. We hope that these names would encourage readers to put together a diversified portfolio for the long-run.
