# Teardown — AAPL, two years of price action

> One SQL query over the credential-free wasm lane against a 33 KB Parquet extract; 506 rows x 11 columns; why only a dataset sqlName is bindable and a display label fails quietly.

# Apple, up 44% with a 19% hole in the middle

Apple daily OHLCV, dividend-adjusted · 2015–2017 · 506 trading days

Two years of Apple price data, published public. One query fetches a 33 KB Parquet extract; the window is closed, so the data stays as of 2017-02-16.

![A dark dashboard titled "Apple NASDAQ: AAPL — two years of price action". A row of five statistic cards, each with a sparkline: adjusted close $135.35 (+43.6% on the prior window), window return +43.9%, annualised volatility 20.5%, max drawdown −18.9%, median daily volume 31.1M. Below them a candlestick price chart from February 2016 to February 2017 with a blue moving average and dotted Bollinger bands, and a green-and-red daily volume histogram underneath it.](https://vibedasher.com/showcase/shots/aapl-two-years-of-price-action.webp)

## The question it answers

Trend, drawdown, the shape of the return distribution, the calendar, and whether volatility was clustering.

## The data, and over what period

A closed window, loaded once. A demonstration dataset, not a market feed.

## How it gets its rows

One query, in your browser, with no key.

## What comes back

506 rows × 11 columns. Every statistic is derived from them in your browser.

## What was hard

Max drawdown is not the low minus the high. It needs a running peak, so a 19% fall from February’s top still counts even though the price later went past it.

## What happened after the build

Frozen. A closed two-year window.

The live dashboard loads from the viewer host. Nothing is fetched from it until you ask, so this page does not touch that origin unless you want it to.
