This is an exchange traded note (ETN) that tracks a covered call strategy index on the physical gold ETF GLD. While maintaining a notional long position in GLD, it sells slightly out-of-the-money call options each month and uses the premium received as the source of its distributions.

It suits investors who want to keep gold exposure while receiving regular cash flow based on option premiums, and who can accept the issuer's credit risk.

It is a passively managed (index-tracking) product run by UBS.

It tracks a covered call strategy that maintains a notional long position in GLD while selling call options each month with a strike price somewhat above the underlying price. The net premium received from the call options is distributed monthly, and if the gold price rises above the strike price, any further gains are given up to fund the distribution, so capital appreciation is capped.

• A structure combining physical gold exposure with option premium income
• Issued as an ETN, so it is tied to the issuer's credit

Assets under management (AUM) are $174.1M, and the total expense ratio is an annual 0.65%.

Unlike GLD, an ETF that holds gold directly, or low-fee gold ETFs, it prioritizes distributions through option premiums, at the structural cost of limited upside potential.

Distributions and the reference price move with the gold price and the option volatility environment. In strong gold markets, the capped upside structure can cause it to lag direct gold holdings. The higher the volatility, the more favorable the conditions for collecting option premiums tend to be.

Safe-haven demand, real interest rates and the dollar's direction drive fund flows across gold-related products. Interest tends to rise when demand for income and demand for gold exposure overlap, and given the ETN structure, its asset size falls in the small to mid-sized category.

Its strength is offering gold exposure together with distributions based on option premiums, while capped upside and issuer credit risk are the main drawbacks.

It can be compared directly with SLVO, a sister product from the same issuer that applies the same covered call structure to silver. If you want gold exposure itself, you can consider alternatives such as GLD, a physical ETF that invests in gold without option constraints, and lower-fee products like GLDM and IAU. If your focus is option income itself, GLDY, a gold option income product from another manager, is also worth comparing.

Here are the points to check before investing in GLDI. The structure seeks gold exposure and option-based income together, but the ETN issuer's credit risk and the capped upside from the covered call should be thoroughly verified before investing.

The key risks are issuer credit risk and capped upside. Because an ETN is an unsecured debt obligation of the issuer, losses can occur regardless of the underlying asset if the issuer's credit deteriorates, and in strong gold markets the covered call structure limits upside returns.

It can be one option for investors who want to add option-based income to gold exposure. However, if the goal is pure gold exposure, physical ETFs such as GLD and GLDM may be more suitable, and if participating in gains matters more than income, a product that gives exposure to gold without option constraints may fit better.
