This is an actively managed ETF that holds energy stocks, master limited partnerships, and investment-grade and high-yield bonds together, with distribution income as its first priority. It moves between equities and credit across the energy value chain to capture opportunities.

It suits income-focused investors who want distribution income from the energy sector along with active adjustment of the asset mix.

It is an ETF run with an active management approach by Tortoise.

Across the energy value chain, the fund moves between stocks, master limited partnerships, and investment-grade and high-yield bonds, actively allocating assets to the opportunities it considers especially promising. It prioritizes distribution income centered on midstream infrastructure and, when needed, may also use option strategies such as covered calls to supplement returns.

• Active allocation across stocks, MLPs and bonds
• An energy income strategy centered on distribution income

Assets under management (AUM) stand at $602.0M, and the total expense ratio is 0.85% per year.

Compared with traditional energy stock ETFs or MLP ETFs, the main points of comparison are its asset mix, which combines stocks and bonds, and its focus on distributions.

Energy assets move with oil and natural gas prices and infrastructure demand, and midstream infrastructure tends to show steadier distribution flows than volatile commodity prices. Because the fund holds both stocks and bonds, its volatility may be somewhat lower than that of a pure equity energy fund.

Fund flows into energy income products shift with the oil price outlook and the interest rate and credit environment, and demand aimed at high distribution income can also move money into related product groups. It is also worth watching how performance changes with the energy cycle and shifts in infrastructure policy.

Flexible asset allocation and high distribution income are its strengths, while energy sector concentration, oil price sensitivity and active management fees are considerations.

Alternatives with similar energy income exposure include AMLP and MLPX, which focus on midstream MLPs, and for broad energy stock exposure, a sector ETF such as XLE is also worth comparing. Those who want midstream infrastructure held mainly through equities can also consider a product such as EMLP. What sets this ETF apart is that it pursues energy income through active asset allocation across stocks and bonds.

These are the points to review before investing in TNGY. High distribution income and flexible allocation are attractive, but sector concentration, oil price sensitivity and management fees should be checked in advance. It is also a good idea to compare it with similar energy and MLP products.

Swings in oil and natural gas prices and changes in energy policy are the main short-term variables, and because the fund is concentrated in a single energy sector, losses can be large during market crashes. Even with bonds in the mix, sector risk remains.

It is a suitable candidate for income-focused investors who want to actively pursue high distribution income from the energy sector. If you want to focus on MLPs, consider products such as AMLP and MLPX; if you want flexible energy income that moves across stocks and bonds, it is advisable to compare this product alongside them before choosing.
