Every portfolio on earth gets performance attribution. No one's judgement ever has.
XA measures the thing finance never has: the call itself — timestamped, settled against the market, decomposed into the skill that made it.
Somewhere in your last hundred calls is the empirical answer to what you're actually best at. No desk runs that analysis on you; the industry attributes returns to portfolios and books, never to judgement. XA runs it: every settled call graded on accuracy, timing, return quality and calibration — and, as your record deepens, those grades cut by asset class, sector, region, holding period and market regime, and split across your own calls, your reads of other analysts, and your reads of the crowd. Whether your edge is energy or tech, Europe or EM, entries or exits — the record answers with evidence.
Private by default
Your calls are visible to nobody unless you choose otherwise. Share inside a circle you define — a desk, a group of peers, a former team — or keep the record entirely to yourself. Either way it is timestamped, settled, and tamper-evident.
Audited by settlement
Reference prices freeze at submission; calls settle at their stated horizon, graded against the volatility of what was called. The only critic involved is what happened next — applied by the same published method, to everyone, without exception.
Conviction as signal
Staking UPC on a call makes the claim costly, and costly claims carry information — the record distinguishes your table-pounds from your musings, because you told it which was which.
Feedback the industry doesn't give
Funds attribute performance; they rarely explain judgement. XA returns each settled call with its decomposition — which dimension carried it, which cost it — building an evidence base on your own decision-making that no employer has ever handed you. (Written feedback on full records is rolling out through the beta.)
What XA is not: not a brokerage, not execution, not a place positions are held or revealed. Calls are statements of judgement settled against public prices — your book stays yours, and nothing here constitutes advice or a market in anything.
// The record travels
A record built here is yours — to keep private, to show a circle, or one day to put in front of an allocator with the timestamps to survive diligence. And in aggregate, anonymised, the crowd's records become the signal institutions buy; contributors share in that as it monetises. The full integrity and data model is stated plainly on the signal page.
