SURVYR. Physical AI Grid & Power
14-stock systematic rules model targeting the 4 physical bottlenecks of AI compute: 30% Independent Power & Nuclear Baseload, 30% High-Voltage Grid & Thermal Cooling, 25% Fiber/Data-Center EPC & Optical Interconnect, and 15% Compute & Silicon Anchor.
Backtest +33.0% a year vs S&P 500 +15.2% (2016–2026, hypothetical)14 holdings · updated Oct 1, 2026
Since it started being tracked live at the Oct 1 close, it is down 6.4%, while the S&P 500 was up 0.7% over the same days. That is 7.2 points behind.
In a simulation on past data (2016–2026), these rules averaged a gain of 33.0% a year, against 15.2% a year for the S&P 500. A simulation is not a real result, and real results are usually lower.
Its deepest fall from a high in that simulation was 18.4% (the S&P 500's was 23.9%).
It holds 14 stocks and the rules re-run monthly; the next re-run is Oct 30.
This describes a research model. It is not advice, and no one's money is in it.

How it's measured · not investment advice
The published weights, held from the Oct 1, 2026 close and reset only at dated rebalances, valued at delayed daily closes (Yahoo Finance). No backtest figures. In the first year, YTD counts from the start close. Before fees, taxes and trading costs. Research only, not investment advice; SURVYR. doesn't manage money. Not yet: 1M, 3M, 6M, 1Y, until the live record is that long.

How it works
What it owns. 14 US-listed infrastructure and compute leaders across four structural sleeves: 30% Independent Power & Nuclear Baseload (CEG, VST, NRG, TLN), 30% High-Voltage Grid & Thermal Cooling (GEV, VRT, ETN, PWR), 25% Fiber, Data-Center EPC & Optical Interconnect (ANET, DY, CIEN, MTZ), and 15% Compute & Silicon Anchor (NVDA, AVGO).
How positions are weighted. Within each sleeve, constituents are weighted by Inverse-Volatility x 6-Month Momentum (6M return divided by 60-day realized volatility), subject to a strict 9.0% maximum single-stock cap at rebalance.
How trend protection works. At each monthly rebalance, any constituent closing more than 8% below its 200-day moving average rotates its sleeve weight into BOXX / SGOV T-bills until it reclaims its 200-day average.
Which stocks qualify. US-listed companies ($2B+ market cap, $20M+ daily dollar volume) with contracted power/grid/optical backlog or positive free cash flow directly supplying AI data-center power, cooling, interconnect, or silicon.
What can go wrong. Concentrated exposure to hyperscale data-center capital expenditure means a slowdown in cloud AI capex or power-market regulatory changes can impact all four sleeves simultaneously.
Universe: US-listed AI power generation, grid equipment, thermal management, fiber EPC & compute leaders ($2B+ market cap).

Disclosures
Systematic 14-stock rules model targeting the 4 physical bottlenecks of AI compute: 30% Independent Power & Nuclear Baseload, 30% High-Voltage Grid & Thermal Cooling, 25% Fiber/Data-Center Engineering & Optical Interconnect, and 15% Compute & Silicon Anchor.
Position sizing: weighted by Inverse-Volatility x 6-Month Momentum with a strict 9% maximum cap per stock, rebalanced monthly.
Trend discipline: any constituent closing more than 8% below its 200-day moving average at month-end automatically rotates its sleeve weight into BOXX / SGOV T-bills until trend recovery.
Trading costs of 10 bps per side are deducted at every monthly rebalance. Backtest results are hypothetical and do not predict future returns.
Costs: 10 bps per side ($2B+ market cap) on every dollar traded; no taxes or other slippage; cash earns 0%. Backtests are hypothetical.
