3. One company and its price

Chart anything together (G)

G puts any series (a price, a statement line, a multiple, an economic series or a formula) on one timeline so you can see whether they move together.

Why you would care

"NVDA went up because revenue exploded." Did it? Price is one line, revenue is another. Until you see them on the same dates, the story is a guess. G lets you draw both and look.

The idea from scratch

A series is a list of values with dates: daily closes, quarterly revenue, monthly inflation. Every chart in Gloom is one or more series on a shared time axis.

The trick is that series arrive at different speeds:

  • Prices

    every trading day (or every minute).

  • Revenue and profit

    once a quarter, when the company files its report.

  • Economic data

    monthly or weekly, when it is published.

G lines them up by date. A quarterly number is placed at the date it was filed when that is known, and it stays flat until the next one arrives. So on any day you only see what was public on that day. This is called as-of alignment.

Revenue is the money a company takes in from sales. Net income is what is left after every cost and tax. Chapter 4 explains both properly; here you only need to know they are reported once a quarter.

How you name a series

You type SYMBOL:field:

You typeYou get
NVDA:priceNVIDIA's price
NVDA:revenueNVIDIA's quarterly revenue
NVDA:net_incomeNVIDIA's quarterly net income

Separate several with commas. Economic series (inflation, jobs, rates) have longer names: find them with CAT, described below, and press g to add them.

See it in Gloom

Gloom screenshot: G NVDA: quarterly revenue (blue) and net income (green) as columns over five years
G NVDA: quarterly revenue (blue) and net income (green) as columns over five years. Look at how both start climbing in 2023

open ittype G NVDA:revenue, NVDA:net_income. Type G alone for an empty chart.

The tour:

  1. Title: G NVDA · NVDA, one entry per series.
  2. Range: 5Y selected. Same buttons as every chart.
  3. Legend: Revenue $96.22B and Net Income $59.69B, the latest quarter of each (NVIDIA's quarter ended 26 July 2026). Four quarters added together give the trailing-year totals you see in FA.
  4. The columns: one pair per quarter. Flat around $5 to $8B a quarter from 2021 to early 2023, then a steep climb.
  5. The gap between the bars: net income is a large share of revenue in the later quarters. That ratio is the net margin (chapter 4).

Press s for Series: add, remove, reorder or hide series, and pick each one's style (candles, line, area, columns, steps), axis, panel and scale (linear or logarithmic). Press f for Formulas: the ratio of two series, their spread (one minus the other), or their rolling correlation.

GP, GIP, CMP, GF and GE are the same chart tool with different starting setups. G is the blank canvas.

Practice and recap

Try it3 tasks
  1. In the screenshot, find the first quarter where revenue passed $20B. Roughly when?
  2. Estimate net income divided by revenue for the latest quarter: $59.69B / $96.22B.
  3. Write the G command that would put AAPL's price and AAPL's revenue on one chart.
Common mistakes4 mistakes
  • Reading a flat quarterly line as "nothing changed". It is flat because nothing new was reported until the next filing.
  • Putting a $300 price and a $90B revenue on the same axis. Give one its own axis or panel in Series, or one line will look flat.
  • Taking "both went up" as proof that one caused the other. Two rising lines can share a third cause, or none.
  • Forgetting the units in the legend: B is billions, M millions.

Answers
  1. A list of values with dates.
  2. Revenue is reported once a quarter, so it stays flat between filings.
  3. f. Ratio, spread or rolling correlation.
