The following are new investments that those saving and or living in retirement might consider for their portfolios. We've included commentary from advisers about the investments, as well.

Pacer Funds has launched Pacer US Export Leaders ETF (PEXL), which aims to capture global market growth by screening the S&P 900 for the top 100 large and mid-capitalization U.S. companies with a high percentage of foreign sales and high free cash flow growth and the Pacer CFRA-Stovall Equal Weight Seasonal Rotation ETF (SZNE), a strategy-driven large-cap ETF that seeks to track the investment returns of an index that alternates exposure semi-annually to certain sectors in the S&P 500 Equal Weight Index., which picks investments from the S&P 500 Equal Weight Index and adjusts allocations three times a year based on seasonal trends.

PEXL seems like a gimmick to me, says Lee Munson, the chief investment officer at Portfolio Wealth Advisors. "You will just have a lot of large-cap names in there, so the performance will be based on the size of the firms rather than who they sell to," he says. "The rest is going to be a lot of noise from currency fluctuations. I'd skip it."

Top 10 holdings of PEXL (as of June 30, 2018)

As for SZNE, Munson said any outperformance from an equal weight S&P 500 list of stocks will be from the small-cap premium. "As I doubt much enduring long-term performance will come from sector rotation," he says. "Remember that equal weight is just a fancy way to charge people more for a fund that has a small-cap bias. And over time smaller firms outperform due to their high risk."

AdvisorShares has launched the AdvisorShares Dorsey Wright Micro-Cap ETF (DWMC) and the AdvisorShares Dorsey Wright Short ETF (DWSH). DWMC is an actively managed ETF that seeks long-term capital appreciation by investing in exchange-listed, micro-cap equities with sufficient liquidity that generally have a market capitalization of less than $1 billion. DWSH identifies and short sells securities that demonstrate the highest relative weakness from an investment universe primarily comprised of large-cap U.S.-traded equities.

Jason Browne, the chief investment officer at FundX Investment Group has concerns about DWSH. "The reason to own a hedge is for down markets, yet in most corrections, what does best is mean reversion," he says. "In other words, stocks that had been lagging tend to outperform in pullbacks. If you are looking to be permanently long/short, this may work because momentum outperforms long-term. But a long-term short position tends to be a net loser. As a tactical hedge, this one may fall flat."

DWMC, by contrast, may be more interesting, says Browne. "Micro caps have less analyst coverage, and momentum is a great way to find the winners," he says. "The only issue is liquidity, which may make this costly to trade, especially if you want to sell in a down market."
