Nerodyne operates Vortex, a rules based equity strategy developed and evaluated across more than a decade of market data. Subscribers receive the strategy's current positions, available without a hedge or with a defined put option overlay. You execute in your own brokerage account. We provide research, not management of your capital.
Twelve years of market data, distilled into five businesses and a defined hedge, delivered to members.
Each update contains the strategy's target positions, with tickers and weights, and, for the hedged version, the corresponding protective put options. The positions are published in the members area, you are notified by email when they change, and the information is complete enough to place the trades yourself.
Ticker names are shown to subscribers only
Five distinct businesses, selected from six internal models and verified for growing revenue. The strategy at full strength.
The same portfolio wrapped in a permanent put option overlay. In the two weakest markets of the sample it turned decline into gain.
A broader book of quality companies, the largest stock in the world, a dividend ETF sleeve, and an index hedge. The shallowest drawdowns of the lineup.
Alongside the flagship, the four underlying pure models it draws from, Apex, Anchor, Nova and Pulse, are available on their own. All figures are full sample backtests from 2012 to the present.
Single models, no hedge. Higher return with deeper drawdowns on the left, steadier profiles to the right.
The methodology behind Vortex is proprietary to Nerodyne and is not disclosed. As is standard for systematic managers, what subscribers act on is the output: the positions the strategy holds, when they change, and the corresponding hedge. The underlying rules remain confidential.
Both protected versions carry a permanent hedge built from put options. Vortex Shield holds the concentrated book with a standing ladder of index (QQQ) puts plus protective puts on its individual holdings. The Diversified Shield instead spreads risk across 15 or more holdings and uses the index ladder alone, which produces the lowest drawdown of the three. Both reduce losses in a market decline in exchange for some return in calm periods.
The overlay behaves like insurance: a known cost in quiet years, with a convex payoff in a sharp decline. On the concentrated Vortex Shield this materially changed the two weakest markets of the sample. In 2022 it returned +16% against −2.5% unhedged and −18.2% for the S&P 500, and in the 2020 decline +64% against +43% unhedged.
The Diversified Shield moves less in the extremes by design. A book of 15 or more quality companies, the biggest stock in the world, and a dividend-leaders ETF sleeve returned +22% per year with a −34% maximum drawdown, the shallowest of the three. The common trade off is lower returns in calm years.

The portfolio changes infrequently. When it does, subscribers are notified by email and the members area shows the new positions immediately.
An optional put option overlay intended to reduce losses in a market decline. Available as a separate version.
