Our read on each fund

ETF.net Research

CGWCInvesco S&P Global Water Index ETF

TBLUBTortoise Global Water Fund

In short

CGW Water treated as a global trade, not a US one. CGW has tracked the S&P Global Water Index since 2007, holding roughly 70 developed-market names across the utilities and equipment makers that keep water moving.

TBLU Tortoise didn't license a water benchmark, it built one. TBLU tracks its own global water index, ESG screened, for 0.40% a year.

Stated mandate

CGW The Fund seeks to track, before fees and expenses, the investment results of the S&P Global Water Index.

TBLU The Fund seeks to track, before fees and expenses, the total-return performance of the Tortoise Global Water Net Total Return Index.

Why people hold it

  • CGW Launched in 2007, so it has carried the water theme through a full cycle of thematic booms and busts, and has grown into one of the larger funds in a small category.
  • Global by design: the mandate spans developed markets worldwide rather than US-listed water plays only, and it follows the S&P Global Water Index instead of a manager's hunches.
  • The basket does what the label says: roughly 70 water names, no unrelated filler. One of the tighter mandate fits among water funds.
  • TBLU Costs 0.40% a year, at the low end of the water category and under the bigger water funds FIW, CGW and PHO.
  • Tracks the in-house Tortoise Global Water Net Total Return Index: water companies worldwide, with an ESG screen written into selection.
  • Trading since 2017, so it has a real operating history rather than a launch-week theme deck.
  • Stands in the upper half of a small water-ETF peer group, helped by the cheap fee.

Worth knowing

  • CGW The 0.58% fee sits right at the water group's median. TBLU charges 0.40% and FIW 0.50%, so cheaper routes into the theme exist.
  • Trades thinly next to broad-market ETFs, so spreads can widen, especially early and late in the session. Limit orders are the standard tool.
  • One theme, about 70 stocks: results can wander a long way from a broad global index in either direction. Cash also arrives once or twice a year, not monthly.
  • TBLU Thinly traded next to the category's largest funds, so spreads can be wider and big orders need more care.
  • The benchmark is Tortoise's own index, not a third-party one, so cross-provider methodology comparisons take extra digging.
  • One theme, global scope: it can move a long way from a broad world equity fund in either direction. Cash comes once or twice a year, not monthly.
