Interaction Model Evolution

Interactive Prototypes

Two fully interactive prototypes with real NVIDIA financial data. Click the tabs, switch statements, toggle estimates—everything works. Navigate to the Financials sidebar tab to see the enhanced view.

ApproachMatched the existing Data Grid pattern—same 21px rows, sticky first column, #102136 headers. Flat data layout with 10 fiscal year columns and 5 statement tabs.
Key DecisionUsed the portfolio table column pattern (highlight column for Current/LTM) to maintain visual consistency across the platform.
StatusShipped as baseline. Foundation for V2 enhancements.
ApproachAdded user estimate rows with contenteditable cells, delta badges (beat/miss), and a consensus comparison mini chart. Toggle switch for estimates visibility.
Key ChangeHistorical data muted to #666, forecast columns accent-tinted with cyan. Key metrics (Revenue, Net Income, EPS, FCF) get inline estimate rows.
StatusIn review. Estimates interaction model being validated with analysts.

Interactive prototypes are best experienced on desktop where you can click through the full UI.

Product Context

The Fragmentation Problem

Institutional analysts live in a world of fragmented tools. Bloomberg for financials. Their RMS for notes and research. A separate platform for transcripts. Another for filings. Every time a portfolio manager asks “what’s our view on NVDA?”—the analyst has to context-switch across four or five applications to assemble an answer.

The core design challenge: how to let an analyst move between market data, internal research, historical financials, notes, and estimates without losing context or switching tools.

Arcana had already built a powerful Research Management System with 33,000+ notes from real hedge fund clients. The research existed. The portfolio data existed. Factor analytics existed. But when an analyst wanted to go deep on a single name, they still had to leave Arcana to see the actual financial data—the income statements, balance sheets, and cash flows that ground every investment thesis.

The question wasn’t whether to build a single stock view. It was how to make it the place where research and market data converge—something no competitor had done well.

Before

  • Financials on Bloomberg, research in Arcana RMS
  • Notes disconnected from the numbers they reference
  • Analyst estimates trapped in Excel spreadsheets
  • No way to compare personal conviction vs. consensus
  • Context-switching kills flow during live market hours
→

After

  • Financials, research, and transcripts in one view
  • RMS notes surface alongside the ticker they reference
  • Inline editable estimates with live delta badges
  • Consensus vs. user estimate comparison chart
  • One surface, zero context-switching

Design Strategy

One Ticker. Everything You Know About It.

The single stock page is built around a clear principle: when you click a ticker, you should see everything Arcana knows about that name. Not just price. Not just portfolio weight. Everything—the chart, the news, the earnings call transcript, the financials, the team’s research notes, and analyst estimates.

Five views, one sidebar, zero navigation overhead. Click “Financials” and you’re looking at 10 years of NVIDIA data. Click “Transcripts” and you’re reading Jensen Huang’s last earnings call. Click “Files” and you’re in the SEC filings. Every view shares the same ticker context. Every view can surface RMS notes tagged to that name.

For data-heavy decision tools, the design needed to balance information density with readable hierarchy. Inline estimates with live delta badges turned a reference view into something analysts could think in. The challenge was maintaining clarity in financial decision workflows where a single misread number has real consequences.

“The best research tool is the one that doesn’t make you leave to find the answer.”

The design thesis that drove every decision: reduce the distance between insight and action. An analyst reading an earnings transcript should be one click from the income statement that transcript discusses. A PM reviewing financials should see their analyst’s research notes without opening a new tab.

Workflow Architecture

How RMS Notes Empower Every View

Arcana’s RMS isn’t a silo. Every note in the system is tagged to tickers, sectors, and event types. When an analyst opens the single stock page for NVDA, the platform already knows which of the 33,000+ notes are relevant. The workflow architecture is built on a structural advantage no competitor can replicate—because no competitor owns both the research layer and the analytics layer.

The structural insight is that notes aren’t just documents—they’re structured data. Every note has a ticker tag, a note type (meeting, earnings, thesis), custom fields, and a timestamp. This structure lets the single stock page pull the right notes at the right time. When reviewing Q3 2025 earnings, the platform surfaces notes the team wrote during that quarter’s earnings call. When editing FY2027 revenue estimates, it surfaces the thesis notes that inform that forecast.

This is the multiplier effect: every note written in the RMS makes every other surface in Arcana smarter. The 33,000+ notes aren’t just stored—they’re woven into the analytical fabric of the platform. The single stock page is where that workflow architecture becomes most visible.

Information Architecture

Five Views. One Research Surface.

The single stock page consolidates five distinct research activities into a sidebar-switched layout. Each view is purpose-built but shares the same ticker context, nav structure, and access to the RMS notes corpus. The design challenge was keeping the depth of each view while making the moves between them feel effortless.

Design Rationale

Decisions Behind the Direction

“A financial terminal shows you the market. A research platform shows you what your team thinks about the market. The single stock page is where those two things finally sit side by side.”

The takeaway

An analyst shouldn't have to hold the market in one window and their own team's thinking in another. The work was getting both into a single view without either one drowning out the other.
