$10,000 in VOLT Became $13,750 in Six Months While the S&P 500 Limped to $11,100

VOLT gained 38% YTD as AI data center buildout created surging demand for transformers, switchgear, and cable underpinning the US power grid.

SPY returned 11% over the same period, less than a third of VOLT's gain, as the AI bottleneck shifted from chips to substations.

After a 67% trailing-year run, VOLT's upside now depends on sustained hyperscaler capex, tight transformer supply, and grid-friendly policy remaining intact.

A $10,000 position in the Tema Electrification ETF ( NASDAQ:VOLT ) on the last trading day of 2025 was worth about $13,750 at the close on June 4, 2026. The same $10,000 dropped into the S&P 500 on the same morning, via the SPDR S&P 500 ETF Trust ( NYSEARCA:SPY ), was worth about $11,100. VOLT is up about 38% year to date against SPY's 11%, and the gap is not because VOLT owns three names that went vertical. It is because the thing the fund was built to own, the physical guts of a power grid that has to roughly double to feed AI, finally started getting paid like oil used to be paid.

VOLT is a young fund, having listed on December 1, 2024, so any five or ten year chart you see for this ticker is reconstructed and worth ignoring. The honest window is the one since inception, and the honest framing is the one for 2026 alone. Shares opened the year at $28.93 and closed June 4 at $39.78. Over the trailing twelve months the fund is up about 67%. Assets followed the price. The ETF crossed $500 million in AUM within 18 months of listing, and Stock Titan flagged the fund as sitting in the 1st percentile of its Morningstar Category year to date.

The expense ratio is 0.75%, which is on the higher side for an equity ETF but in line with thematic funds that have to do real screening work. The prospectus says VOLT puts at least 80% of net assets in common and preferred stocks of publicly listed companies directly or indirectly economically tied to global electrification, including electrification materials supply, equipment and services, and electricity storage. Translated, that is the picks-and-shovels list. Transformers, switchgear, cable, copper, the companies that make the equipment that moves electrons from where they are generated to where a GPU eats them.

The mechanism here is not complicated, and that is part of why the trade keeps working. AI data center buildout is the most physical tech story in a generation. PineBridge's 2026 equity outlook puts it bluntly, calling datacenter equipment growth essentially locked in for the next four to five years, given outsized demand coupled with supply constraints related to electrical transmission and distribution and the electrical infrastructure, and pegs the annual growth rate at around 25% annually. Goldman Sachs frames the same point from the grid side, noting that in the US, assets in the power grid infrastructure average 40 years old, a structural mismatch to the loads now being asked of them.
