Both passports. One research desk.
The only AI research desk built for investors who hold both sides of the 49th parallel — TSX and NYSE, NASDAQ and TSX-V. Quinn tracks 59 dual-listed pairs, MJDS spreads, FX-adjusted arbitrage, and treaty-aware cross-border tax in near-real-time.
What a cross-border investor gets.
US-only tools quietly break every Canadian tax mechanic. We assume you file in both.
Cross-Border Arbitrage
FX-adjusted spreads on 59 dual-listed US/Canada pairs — the price gap between a TSX and NYSE listing that retail screeners never surface. Spot the window before it closes.
59 pairs · FX-adjustedTreaty-Aware Tax
MJDS spread carry, treaty withholding, superficial-loss vs wash-sale, flow-through (FTS) credits, NR-301 and Form 1116 — the cross-border tax math, computed for the right passport.
MJDS · treaty · FTSDual-Filing Coverage
The SEC record for both sides of a dual listing — EDGAR filings, the MJDS 40-F / F-10 cross-border record, and Form 4 insider transactions for the names you hold, side by side instead of in two terminals.
