🔷 Prism

A local financial analysis dashboard. Search any stock ticker to get a comprehensive view of financials, valuation, options flow, insider activity, SEC filings, and news — all in your browser.

Features

Market Bar

Live S&P 500, NASDAQ, DOW, and VIX at the top of every page.

Overview

Score card — at-a-glance green/yellow/red signal badges for Valuation, Growth, Profitability, Leverage, Momentum, and Short Interest
52-week range bar — visual indicator showing where the current price sits between the 52W low and high, with % context
Short interest — % of float, days to cover, shares short vs. prior month
Price chart (1M / 3M / 6M / 1Y / 5Y), key stats (market cap, P/E, volume, beta)

Financials

Annual and quarterly Income Statement, Balance Sheet, and Cash Flow Statement with year-over-year % change columns color-coded green/red (cost/debt rows are correctly inverted). CSV export on every statement.

Valuation

Seven sub-tabs:

+ + + + + + + + + + + + + +

Tab	Contents
Key Ratios	P/E, Forward P/E, P/S, P/B, EV/EBITDA, EV/Revenue, margins, ROE, ROA, ROIC, D/E, current/quick ratio, interest coverage, dividend yield, payout ratio
Historical Ratios	Annual P/E, P/B, P/S, EV/EBITDA, margins, ROE, ROA, D/E charted over time
DCF Model	Adjustable WACC, terminal growth, projection years, FCF growth; waterfall chart; EV/EBITDA implied price below
Comps	Peer valuation table with editable ticker set
Forward Estimates	Analyst revenue, EPS, and EBITDA estimates with low/avg/high ranges and chart overlay
Analyst Targets	Price target range (low/mean/median/high), upside to mean, recommendation distribution chart
Earnings History	EPS actual vs. estimate, surprise %, color-coded table, chart; CSV export

All Key Ratios are self-computed from raw yfinance quarterly statements — no FMP quota consumed.

Options

Put/call ratio by volume and open interest (with Bullish / Neutral / Bearish label)
IV smile chart (calls and puts) with ATM marker
Open interest by strike (calls above axis, puts mirrored below)
Full options chain table (expandable)

Insiders

Buy/sell transaction history with monthly activity bar chart and filterable table.

Filings

Recent 10-K, 10-Q, and 8-K filings with direct EDGAR exhibit links, color-coded by type.

News

Recent articles with Bullish / Bearish / Neutral sentiment badges and a 7-day sentiment summary.

Setup

1. Navigate to the project

cd ~/Work/prism

2. Activate the virtual environment

source .venv/bin/activate

3. Add API keys

cp .env.example .env

Open .env and fill in your keys:

FMP_API_KEY=your_key_here
+FINNHUB_API_KEY=your_key_here

Both are free:

FMP (Financial Modeling Prep) — financialmodelingprep.com — 250 requests/day
Finnhub — finnhub.io — 60 requests/minute

No keys? Most of Prism still works. Overview, Financials, Key Ratios, Historical Ratios (yfinance fallback), Options, Insiders, Filings, and the DCF model all run without any API key. The Comps peer list, Forward Estimates, and News require FMP/Finnhub keys.

4. Run the app

streamlit run app.py

Opens at http://localhost:8501

Daily Usage

cd ~/Work/prism
+source .venv/bin/activate
+streamlit run app.py

DCF Model Notes

The DCF uses historical Free Cash Flow from yfinance and projects forward using your chosen assumptions:

+ + + + + + + + + + +

Input	Default	Range
WACC	10%	5–20%
Terminal Growth Rate	2.5%	0.5–5%
Projection Years	5	3–10
FCF Growth Rate	Historical median	−20–30%

Terminal value uses the Gordon Growth Model. Enterprise value is bridged to equity value using net debt before calculating value per share. The FCF growth slider defaults to the historical median and can be overridden.

The EV/EBITDA section derives an implied price from a target multiple applied to trailing EBITDA (sourced from the income statement, not the info dict). The slider defaults to the current computed market multiple.

API Usage

+ + + + + + + + + +

Source	Limit	Used For
yfinance	None	Price, financials, options, insiders, filings, all key ratios
FMP (free)	250 req/day	Peer discovery, forward estimates, historical ratios, news
Finnhub (free)	60 req/min	News sentiment

All key ratios are computed locally from quarterly statements — Prism only calls FMP for data that cannot be derived from raw statements. Data is cached per session (financials: 1h, news: 10min, indices: 5min, options: 15min).
