Exchange-traded funds offer a convenient way to invest in sectors or niches that interest you. If you think there's money to be made in focusing on companies where insiders have been snapping up shares, the Guggenheim Insider Sentiment ETF
ETFs often sport lower expense ratios than their mutual fund cousins. The Insider ETF's expense ratio -- its annual fee -- is 0.60%, which is a bit higher than many ETFs, but stil far lower than the typical stock mutual fund.
This ETF has performed reasonably well, outperforming the S&P 500
With a low turnover rate of 65%, this fund does a fair amount of trading, although it isn't frantically and frequently rejiggering its holdings as many funds do. The turnover simply reflects the changing purchases of insiders.
