The investment approach
Built for what’s next.
Leadership is earned—and it can change. Time Machine searches the S&P 500 for businesses with sustained market strength, financial evidence and a credible opportunity ahead. Its 35-stock model gives those ideas a place in a portfolio, rather than leaving you with an expanding list of names.
How the model works
Momentum helps identify potential leaders. Statement-backed fundamentals and AI research challenge the investment case. Incumbents and eligible challengers are reviewed for a meaningful overall advantage after uncertainty, valuation, costs and portfolio risk. Evidence and consecutive-session confirmation are required before an authorized replacement; a higher daily rank alone is not enough.
What you can follow
A stock leadership subscription should help with the decision to keep owning a business as well as the decision to buy it. Time Machine publishes holdings, actual position weights and recorded changes so you can follow that process.
What we're watching
Watch financial acceleration, adoption, competitive progress and the valuation needed to justify the opportunity. Future milestones are tests of the thesis, not facts that have already happened. Experimental long-range scenarios are not validated ML predictions or promises of future market leadership.
Clarity before commitment
Questions about Time Machine
Does daily research mean daily trading?
No. A holding can remain in the model after review. Replacements must meet the authorized evidence and confirmation requirements.
Are the five-year scenarios predictions?
No. Experimental future scenarios describe assumptions to test. They are not calibrated predictions, guaranteed outcomes or a substitute for current evidence.
What does the subscription include?
Access to the model dashboard, published holdings and weights, available company stories, dated performance where supported, and its scheduled morning email. Subscription research is not personalized advice or managed-account execution.
How does the free trial work?
The advertised trial is seven days for eligible subscribers. A card is required. After the trial, this plan is $199 per month unless canceled before the trial ends. Eligibility and final terms appear at checkout.
Can I use my own brokerage account?
Yes. You decide whether and how to implement research in your account. Stock Pro does not execute subscription trades for you. Taxes, costs and your personal situation can make your results different from the model.
