A terminal that reads the market — and reads you.

Overnight, Contra scans the stock, commodity, and bond markets for the patterns that quietly move returns — dividend traps, fake earnings beats, post-merger leverage stress, insider buying clusters, commodity-cycle turns, rate-regime shifts, and many more. Each name gets one clear read: engage, quality, monitor, avoid, crowded, or an honest “no view.”

Every pattern is defined in the open: what it means, what triggers it and exactly what would prove it wrong. You can check our homework.

Connect your brokerage (read-only — Contra can never trade for you) and it reads your real, closed trades. It grades how well you timed each exit and surfaces the habits quietly costing you money: banking winners early while letting losers run, chasing a stock after the move, selling on a price scare instead of a broken thesis, buying names the framework was flagging to avoid.

Each habit comes with the number behind it and the drill that fixes it — so the same mistake stops costing you twice. The verdict stays yours.

A short diagnostic maps how you read the market across nine skills. From there, blinded historical replays, a counter-argument engine that argues against your own thesis, and a conviction tool that adds friction exactly when it’s easy to over-bet all push those skills forward. Your profile grows from your real decisions and trades — not a quiz score you game once.

Contra is built by an operator, not a content team. Semih Decan has spent more than twenty years inside the numbers of large consumer, retail and technology companies: as a finance leader at Procter & Gamble, as a McKinsey partner, as the CEO of a turnaround, and as the commercial chief of a growth-equity-backed marketplace. The work was always the same question: what does an operating pattern look like in the numbers before it reaches the stock price?

Retail investors get picks and charting tools, and almost nothing that tests their own decisions. Contra applies the operating patterns he spent a career reading, defines each one in the open with the condition that would prove it wrong, and grades your own closed trades against the same standard.
