Stock Rover has been around for more than a decade, and it shows — in a good way. It's the tool power-user fundamental investors reach for when they want to express a screen across hundreds of metrics, import positions from a brokerage, and see ten years of financials without clicking through filings. Tessera Alpha is a newer, narrower tool with a different center of gravity: systematic signal generation, full-portfolio backtesting, and regime-aware position management.

Both are real products that do real work. They're not interchangeable. Here's how to pick.

TL;DR

| Feature | Tessera Alpha | Stock Rover | | --- | --- | --- | | Screener depth | ~24 core quality factors + sector-relative overlays | ~650 screening metrics | | Backtesting | Full-portfolio with rotation, regime, honest bias handling | Screen-level (rule backtesting) | | Signal generation | Yes, 24-factor scoring with weekly rebalance | No | | Regime detection | Yes, breadth-based (5 regimes) | No | | Broker sync | Not yet | Yes (Fidelity, Schwab, and others) | | Pricing | Tiered (see /pricing) | Free, Essentials ~$79.99/yr, Premium ~$179.99/yr, Premium Plus ~$279.99/yr |

What each is best at

Stock Rover is depth. Around 650 screening metrics, ten-plus years of historical financials rendered in-app, their own fair-value calculators (variations on DCF and multiples), correlation analysis between tickers, integrated research reports, and — importantly — portfolio tracking with direct brokerage import for tax-lot accounting. If your workflow is "write a custom screen, read the research, place the trade myself, track it alongside my actual holdings," Stock Rover is purpose-built for that loop.

Tessera Alpha is narrower on screener breadth but pushes further into the system side. The 24 quality factors feed a Tessera Rating; stocks are ranked by P/E discount relative to their sector median rather than against an absolute threshold; a breadth-based regime detector tilts exposure between bull and bear; and competitive rotation swaps weakest holdings for strongest candidates when the score gap hits >=0.20. The whole thing runs inside a portfolio-level backtest with point-in-time universes and as-reported financials, so you're not looking at a curve that benefits from survivorship or look-ahead.

When Stock Rover wins

• You want the biggest possible screener. ~650 metrics, custom formulas, saved views. If you need a filter Tessera doesn't expose, Stock Rover probably has it.
• Broker sync and tax-lot tracking matter. SR imports from Fidelity, Schwab, and other major brokerages and tracks lots for tax purposes. Tessera doesn't do this yet.
• You want ten-plus years of historical financials at your fingertips. SR renders long histories inline without round-trips to filings.
• Your workflow is screen → research → manual trade. SR has integrated research reports and fair-value calculators designed for exactly that loop.
• You already pay for it and it works. Ten years of product maturity is a real asset. Don't churn away from a tool that fits.

When Tessera wins

• You want the system to propose trades, not just filter ideas. Tessera's signal layer produces ranked buy and exit candidates weekly. Stock Rover filters; it doesn't decide.
• You want full-portfolio backtesting. Not "does this filter rule backtest well in isolation" but "does the whole strategy — entries, exits, rotations, regime tilts — hold up over five or ten years with honest bias handling."
• You want regime-aware exposure. Tessera's breadth-based detector shifts how aggressively the portfolio deploys capital across bull, neutral, bear, and crisis regimes. That logic isn't in SR.
• Sector-relative valuation is a core primitive for you. A P/E of 18 means something different in utilities than in software. Tessera treats that as a first-class input; in SR you'd build it with custom formulas.
• You want rotation logic applied mechanically. Competitive rotation — swapping the weakest held position for a stronger candidate at a >=0.20 score gap — runs automatically in Tessera. You'd run this by hand in SR.

Pricing comparison

Stock Rover publishes pricing publicly: a free tier, Essentials at ~$79.99/yr, Premium at ~$179.99/yr, and Premium Plus at ~$279.99/yr. Billing is annual-only at the paid tiers, which is worth knowing if you want monthly flexibility.

Tessera Alpha runs a tiered plan — current pricing lives at /pricing rather than in this post, because we'd rather you see the live numbers than outdated ones here.

Neither tool is expensive relative to the cost of a single bad trade. Pick the one that matches your workflow; don't optimize for $100/year either way.

Feature-by-feature breakdown

| Capability | Tessera | Stock Rover | | --- | --- | --- | | Screener metric count | ~24 core quality + sector overlays | ~650 | | Sector-relative valuation | Yes, core primitive | Possible via custom formulas | | Backtesting | Full portfolio, rotation + regime | Screen-level only | | Signal generation | Yes, 24-factor to weekly rebalance | No | | Regime detection | Yes, breadth-based | No | | Broker sync | Not yet | Yes | | Historical financials depth | Yes, point-in-time | Yes, 10+ years | | Tax-lot tracking | Not yet | Yes | | Mobile | Yes | Yes |

Comparing backtesting specifically

This is the area where the two tools differ most, and it's worth pulling apart carefully because "backtest" means different things in each.

Stock Rover's backtesting operates at the screen level. You define a filter rule — for example, "P/E <15, ROIC >15, debt/equity <0.5" — and SR shows you what a portfolio of the stocks passing that filter would have returned historically, often with periodic rebalancing. That's a legitimate and useful tool, especially for evaluating whether a single screening idea has historical legs.

Tessera's backtesting operates at the portfolio level. It simulates the full workflow: dynamic universe discovery each rebalance, 24-factor scoring, sector-relative P/E ranking, regime detection, competitive rotation, trailing stops, position sizing caps. Point-in-time universes prevent survivorship bias; as-reported financials prevent look-ahead. There's an out-of-sample validation layer on top of that. We wrote about why this matters in Methodology: Backtesting Pitfalls — a "backtest" that quietly uses restated financials or today's index membership is not the same kind of evidence as one that doesn't.

Neither approach is wrong; they answer different questions. SR answers "did this filter idea work?" Tessera answers "did this whole strategy work, with bias controls on?"

When you'd use both

This is a plausible combination, and we don't pretend otherwise. Stock Rover for broad ideation — write custom screens across metric combinations Tessera doesn't expose natively, scan through research reports, correlate candidates against your existing book. Tessera for validating and running the strategy systematically — the ideas that survive go into a backtest with full portfolio mechanics, and the live signals feed weekly decisions. SR's broker sync also makes it a reasonable place for tracking your portfolio even if Tessera drives the signal and decision layer.

Honest caveats

• Stock Rover has ten-plus years of product maturity. Tessera is newer. Some rough edges still exist and we keep a public changelog.
• Stock Rover's screener metric count is genuinely broader. If you need 600+ filters or niche formula composition, that's their edge and we don't pretend to match it.
• Tessera's backtest engine is more portfolio-aware, but the underlying screener dataset is narrower. We've traded breadth for depth on the parts we care about most.
• Neither tool replaces a brokerage for execution. Both produce ideas, decisions, and tracking; you still place trades at your broker.
• We're biased. This is our site. We've tried to make the SR strengths concrete rather than handwave past them, but read with that in mind.
