The arena

Eight published strategies, implemented from their authors’ own stated rules and left to compete on a live record. Each publishes a portfolio of twelve names; from that day the site tracks what those names did against the market over the same window. Nothing here is back-fitted — the picks are recorded before the outcome is known.

Tracking since 2026-08-21 across 1 published sessions. That is far too short to separate skill from luck — treat the table below as a scoreboard that has just started, not a verdict.

Today’s portfolios

what each set of rules picks right now

momentumMark Minervini

Only own stocks already in a confirmed uptrend, near their highs, outperforming the market.
Where our version differs: Relative strength is measured as a percentile of one-year return across our universe, in place of the proprietary IBD RS rating.

momentumAndreas Clenow

Rank by the steepness of the trend multiplied by how straight it is, so a single lucky gap cannot buy its way to the top.
Where our version differs: Position sizing by volatility parity and the index-above-200-day gate are part of the published system and are not applied here; this is the ranking only.

momentumAcademic 12-2 momentum

A year of return, ignoring the most recent month because it tends to reverse, and preferring a steady climb to a jumpy one.
Where our version differs: The smoothness filter is the share of up-days over the window, a simpler cousin of the published information-discreteness measure.

momentumWilliam O’Neil

Current quarterly earnings growing hard, price near a new high, and the stock leading rather than lagging its market.
Where our version differs: C, N and L only. Institutional sponsorship and share-supply data are not available for Indian retail feeds, so the S and I of CAN SLIM are missing.

valueJoel Greenblatt

Buy good businesses cheaply: rank every company on both return on capital and earnings yield, then add the two ranks together.
Where our version differs: Profit before tax stands in for EBIT, and equity plus borrowings for capital employed. Greenblatt excludes financials and utilities; we do not, and that matters most for the banks.

valueBuffett-style quality

A business that earns well on its capital, owes little, has been consistently profitable, and is not priced above its own history.
Where our version differs: This is the loosest attribution on the page. Buffett has never published a screen, and the qualitative core of his approach — the durability of a business — is exactly what a screen cannot see. Read it as a quality filter, not as his portfolio.

valuePeter Lynch

Growth is only worth paying for up to a point. Compare the price-earnings multiple with the growth rate behind it.
Where our version differs: PEG uses trailing earnings growth rather than forecast growth, because consensus estimates are not freely available for most Indian mid-caps.

valuePiotroski-style financial strength

Score a company on simple binary tests of profitability, leverage and cash, and prefer the ones that pass most of them.
Where our version differs: Piotroski uses nine signals across two years of annual accounts. India publishes machine-readable balance sheets half-yearly and only since 2025, so five signals are computed and the score is out of five, not nine.
These are our implementations, not these investors’ portfolios. Every one of them describes judgement a screen cannot carry — which businesses are durable, when a market is hostile, how much to hold. Where Indian disclosure does not support a rule, it is approximated, and each card says where. None of these people are associated with this site.
Portfolios are equal-weighted, held for the stated window, and compared against the median stock in our universe over the identical period. No costs are deducted here — see Are the scans working? for what trading actually costs.
