✦ Sample dataOne dataset. Four perspectives.
Switch the view. Understand what changes.
Twenty completed sessions. Price rises from $100.00 to $108.40, with intervening declines. This is an invented sequence, not an instrument quote.
Volume is a separate illustrative observation for each session. More activity does not determine the direction of the next price move.
Solid: sample price. Dashed: five-session simple moving average. The first four averages are unavailable because five observations are required.
Momentum here means five-session rate of change: (current price ÷ price five sessions ago − 1) × 100. It is not RSI or a trading signal.

Portfolio alpha, put in perspective
A return is only part of the story.
Compare the benchmark. Follow the drawdowns. Ask which exposures contributed to the result. A useful performance review makes the assumptions visible.
The examples here show cumulative return and simple benchmark excess return. A risk-adjusted alpha estimate requires a model, not just subtraction.

One invented session-based funnel. Each stage is a subset of the preceding stage. Landing-to-order rate: 36 ÷ 1,000 = 3.6%; checkout-to-order rate: 36 ÷ 120 = 30%.
A separate lens: website intelligence
Measure your website’s performance, too.
Traffic starts the conversation. Acquisition, engagement, and conversion definitions make it useful. Trace a visitor’s journey without losing sight of the denominator.
Website analytics is its own discipline—not the financial measure of portfolio alpha.

Meet AnalyticsAlphaWhat is AnalyticsAlpha.com?
An educational resource for trading analytics, portfolio performance, chart analysis, and website measurement. Explore original guides, interactive sample dashboards, and locally downloadable research files.
Is this a live market dashboard?
No. The chart labs and performance examples use fixed, invented datasets. They are designed to explain calculations and comparisons, not to quote securities or generate trading signals.
Is portfolio alpha the same as beating a benchmark?
Not necessarily. Simple excess return subtracts a benchmark return. A risk-adjusted alpha estimate measures performance relative to a specified model. Those are different calculations.
Can I connect my brokerage account or wallet?
No account connection is offered. The site does not request brokerage credentials, wallet signatures, or seed phrases. The sample chart controls run locally in your browser.
Where should a beginner start?
Begin with the chart-analysis guide, explore fair portfolio benchmarking, then create a journal that separates observations from decisions. The glossary explains the key terms along the way.
Curiosity is a good starting point.
