SignalFlow AI, Long-Short - For Independent Investors

SignalFlow AI Long/Short - An AI-Driven Securities Signal Service From Upstream Development, LLC

Independent Investor Edition

SignalFlow AI Long/Short is a securities signal service based on our proprietary quantitative market model.

We’ve developed machine learning methods able to identify, in real time, material changes in market sentiment in major liquid indices, ETFs and stocks.

The SignalFlow AI model is trained to identify “safer” and “less safe” periods to have capital at work in any of the securities it covers.

We package the model outputs to deliver simple risk on / risk off signals to help you understand when might be best to have capital at work, and when might be best to have capital on the sidelines.

Our first service module was a risk on / risk off signal service for $SPY, the SPDR S&P500 ETF. We then launched a similar service for $QQQ, the Invesco Nasdaq-100 ETF. You can learn more about these long-only services, here.

These long-only signals have proven valuable during the market weakness of Q1 2025, moving to risk-off during the initial part of the selloff - helping long-only investors avoid the worst of the drop.

We now bring you SignalFlow AI Long/Short.

Put simply, SignalFlow AI Long/Short provides a signal service, once daily at the close, stating which of the following ETFs the model believes is the most compelling to own:

• SPY (long S&P500)
• SH (short S&P500)
• QQQ (long Nasdaq-100)
• PSQ (short Nasdaq-100)

The model also considers when it believes it is best to own cash (ie. none of the above ETF positions).

The goal of the model outputs is to enable investors to not just avoid, but to benefit from any periods of market weakness - in addition to benefitting from periods of market strength.

The backtested returns in the last ten years, shown here, illustrate the benefits of this approach.

Signals are issued daily around the close in our members-only Slack channel, and can be discussed in a separate subscriber chat channel.

A subscription to SignalFlow AI Long/Short For Independent Investors costs just $2499/yr or $349/month for the service.

If you already subscribe to the SPY or QQQ signal services, we offer you a 25% discount on this service, plus a pro-rated upgrade path ie. you keep the value of any remaining subscription you have in the long-only services when you upgrade to this Long/Short service. If you’d like to upgrade from the long-only services, contact us here or email us at [email protected] or just reach out in the SignalFlow AI Discussion chat channel in Slack.

As always, our prices will continue to move up over time. Subscribers keep their day one price for as long as they remain members. The sooner you join us, the less you pay.
