Fix valuation review: dead code, wrong peer bands, height scaling

2026-05-17T09:08:26Z

- Remove dead _build_dcf_canvas_html (~525 lines, superseded by _build_dcf_canvas_only_html) - Remove unused ev_ebit assignment - Fix FCF yield KPI strip and mini row using dividendYieldTTM as peer band proxy (pass None — no equivalent peer field for FCF yield) - Expand st.spinner in _render_historical_ratios to cover get_peers() and get_ratios_for_tickers() calls - Collapse _render_all_multiples / _render_multiples_model indirection into a single function - Replace Comps fixed 2600px height with max(1900, 1500 + n_peers*80), saving 400-700px whitespace for typical 5-8 peer sets Co-Authored-By: Claude Sonnet 4.6

Fix Historical Ratios blank render and Earnings History height cutoff

2026-05-17T08:55:53Z

Missing semicolon after pts.forEach() prevented ASI, causing a JS syntax error that silently killed all chart and matrix rendering. Also bumped Earnings History iframe height to stop the table from being clipped. Co-Authored-By: Claude Sonnet 4.6

Redesign Valuation tab: Key Ratios, Models, Historical, Comps, Multiples

2026-05-17T08:33:17Z

- Key Ratios: 6-KPI snapshot strip with sparklines, 5-category ratio grid (Valuation, Profitability, Growth, Health, Cash Returns) via components.html() - Models (DCF): two-column layout — st.slider() rail + prominent verdict chip, EV→equity bridge, per-share reconciliation, cross-check grid as HTML canvas - Historical Ratios: SVG line chart (subject vs sector median) + clickable heatmap matrix that updates the chart via client-side JS - Comps: 4 percentile rank bars + sortable peer table, all via components.html() - Multiples: math-flow columns (EV/EBITDA, EV/Revenue, P/Book) with sensitivity strip and DCF cross-check; HTML range sliders drive JS computation All redesigned tabs: scrolling=False, string-concat HTML (no f-strings), XSS-safe (escape_html on all user-supplied strings injected into HTML/JS).

Fix 5D x-axis labels and weekend/closed fallback for intraday default

2026-05-17T07:10:42Z

- 5D period now uses '%a %H:%M' tick format so each day is labelled (Mon 09:30) instead of bare times that repeat across five days - default_period resolves to '1mo' when 1D series is empty (market closed, weekend, holiday) so the chart isn't blank on first load - JS activePeriod reads from OVERVIEW_META.default_period at boot instead of hardcoded '1d', and bootOverview syncs the active button to match Co-Authored-By: Claude Sonnet 4.6

Add 1D and 5D intraday periods to overview chart

2026-05-17T07:06:36Z

Adds get_intraday_history() to data_service.py (5m/30m bars, ttl=60s) and wires it into the overview chart with HH:MM x-axis formatting, market-hours filtering, intraday-only primary fetch, hidden comparison buttons, and 1D as the default period on load. Co-Authored-By: Claude Sonnet 4.6

Sidebar chrome: vertical nav, live clock, brand v1.2, drop snapshot

2026-05-16T08:52:32Z

Replace horizontal st.tabs() with session-state-driven vertical nav buttons in the sidebar (Workspace section). Remove company snapshot entirely — ticker info is covered by the persistent TickerHeader. Add NYSE live clock between brand and search. Update brand sub-label to "v 1.2".

Rewrite watchlist as custom HTML component with proper styling

2026-05-16T08:40:02Z

Replaces st.button rows with a components.html iframe that renders sym·price·Δ% in a 3-column grid with hairline dividers, monospace fonts, and colored change percentages. Adds hidden text_input click receiver so row clicks update session state. Fixes toggle button to show toast when watchlist cap is hit and removes now-redundant psm-watch-toggle CSS.

Add session-scoped personal watchlist to sidebar

2026-05-16T08:30:34Z

Adds a save/remove toggle below the company snapshot, a watchlist section (capped at 10 tickers) that renders sym · price · Δ% rows above Top Movers, and an empty-state placeholder. Clicking a watchlist row loads that ticker. Co-Authored-By: Claude Sonnet 4.6

Add TickerHeader + KPI strip above tab strip

2026-05-16T08:06:05Z

Injects a persistent header band between the market bar and st.tabs(): sector tag, italic symbol, company name, 52W range rail with price pin, price, and Δ/% change chip; below that a 6-cell KPI strip (Market Cap, P/E, EPS, Div Yield, Beta, Short % Float). All data from cached service calls — free hits. Graceful "—" fallbacks for missing fields. Co-Authored-By: Claude Sonnet 4.6
