Reading crypto and commodities with a stock-market lens

Say you own a few shares of Chevron, some Bitcoin, and you have been eyeing an ETF that tracks copper. You start wondering: does the same kind of analysis even apply to all three? Is "unusual trading volume" in Bitcoin the same idea as unusual volume in a stock, or are you comparing apples to oranges?

Short answer: the mechanics are different in almost every way that matters, but the underlying question you are asking stays exactly the same. That question is simple: is this asset behaving unusually for itself, right now, compared to its own recent past? Once you understand what changes and what does not, you can read a signal on gold, Ethereum, or ExxonMobil with the same confidence. If you have not yet read the basics of what "unusual volume" actually means, our complete guide to unusual volume in stocks is the right place to start before this one.

#Stocks trade in a box. Crypto never stops.

The New York Stock Exchange opens at 9:30am and closes at 4pm, Monday to Friday, US Eastern time. That closing bell matters more than people realize. It gives everyone a clean daily reset. When we say a stock's volume today is "1.35 times its 20-day normal" — which is what Exxon (XOM) showed recently — we are comparing one full trading day to the average of the last 20 full trading days. Clean units, clean comparison.

Crypto has no bell. Bitcoin trades at 3am on a Sunday exactly as it does at 2pm on a Tuesday. There is no "closing volume" because there is no close. So when you measure unusual activity in crypto, you are usually looking at rolling windows — the last 24 hours versus the typical last 24 hours, updated continuously — rather than calendar trading days. The concept (compare today's activity to this asset's own recent history) survives intact. The unit of "today" does not.

#Stocks have earnings. Commodities and crypto mostly do not.

A big chunk of what makes a stock's volume spike is scheduled and knowable in advance: earnings reports, product launches, Fed meetings that affect the whole market. You can often guess why LRCX (Lam Research) or TSM (TSMC) had 11 or 15 news articles in a 48-hour window — chip equipment and chip manufacturing names get swept up together when one big report drops, the way TSM's recent activity score of 53 and 15 fresh articles suggest.

Commodities like copper do not report quarterly earnings. Their volume spikes usually trace back to something happening in the physical world: a mine strike in Chile, a tariff announcement, a factory reopening in China that needs more wiring. When copper recently showed a volume of 2.60 times its own 20-day normal — a genuinely large jump — the driver was not a corporate announcement, it was industrial demand and supply chatter. Same statistical idea, different kind of news feeding it. For a deeper sense of what generally pushes any share price around, including the earnings calendar, our guide to what actually moves a stock price covers the mechanics in full.

#Futures versus spot: the same commodity, two different markets

Here is something that trips people up. When you hear "oil is trading at $80," that price usually comes from a futures contract — an agreement to buy or sell oil at a set price on a future date — not a literal barrel changing hands today. Futures markets have their own volume, their own open interest (how many contracts are currently open), and their own rhythms tied to contract expiration dates.

Spot markets, by contrast, are for immediate delivery. Gold jewelry, physical copper wire, a barrel of oil loaded onto a ship this week. Spot and futures prices track each other closely most of the time, but their volume patterns can diverge, especially near a futures contract's expiration date, when trading activity often spikes for reasons that have nothing to do with the underlying commodity getting more popular. It is simply contracts rolling over. Anyone reading a "volume spike" in oil or copper needs to know which market — futures or spot — that spike belongs to, because they answer different questions.

#ETFs: a workaround for measuring things that do not trade on an exchange

You cannot easily buy a barrel of oil or an ounce of gold on a normal brokerage account, and physical commodity markets do not always publish clean, continuous volume data the way stock exchanges do. This is where ETFs (exchange-traded funds, baskets of assets that trade like a single stock) become useful stand-ins. A gold ETF or an oil ETF trades on a stock exchange, with a stock exchange's clean daily volume numbers, while its price tracks the underlying commodity closely.

This is partly why Momentu can measure Chevron (CVX) and ExxonMobil (XOM) — actual companies — using the exact same stock-market machinery, while a raw commodity like copper needs a different data pipeline entirely, often built around futures volume or ETF proxy volume. The number you see for copper's volume ratio is answering the same question as Exxon's, but it was assembled from different raw ingredients underneath.

#Different crowds show up for each asset class

Stocks are traded by a mix of long-term retirement savers, pension funds, hedge funds, and day traders. Commodities attract a heavier presence of hedgers — an airline locking in fuel prices, a jewelry manufacturer locking in gold costs — alongside speculators. Crypto skews toward retail traders and algorithmic trading bots, with far less of the institutional "buy and hold for decades" money that anchors much of the stock market.

Why does this matter for reading a volume signal? Because the same-sized spike can mean something different depending on who is likely behind it. A volume surge in a stock heavy with retirement-fund ownership is a bigger behavioral break from normal than the same-sized surge in a crypto asset where fast, reactive trading is already the norm. This is one reason Momentu never compares one asset's volume to another asset's volume in absolute terms — only to that same asset's own history. Copper's 2.60x is unusual for copper. It says nothing about whether that is unusual compared to, say, silver or Chevron.

#The one thing that does not change: comparing an asset to itself

Strip away exchanges, futures contracts, earnings calendars, and trading hours, and you are left with one durable idea. Take any number that matters — volume, price movement, how much people online are talking about it — and ask: is this higher or lower than what's normal for this specific asset? Not normal for the market. Not normal for a similar asset. Normal for this one thing, based on its own recent history.

A "z-score," if you want the technical term, is just a way of expressing "how many standard deviations away from typical is this," where a standard deviation is a measure of how spread out normal values usually are. In plain terms: if copper's daily volume normally wobbles between, say, 0.8x and 1.3x its average, then a reading of 2.60x is not just a little unusual, it is far outside copper's usual wobble. That statement is true whether you are talking about copper, LRCX, or a token that did not exist five years ago. The math generalizes. The meaning behind the math — what caused it, what it predicts — does not.

#What unusual volume can and cannot tell you, across every asset class

Momentu's own year-long test across 50 stocks, roughly 10,500 separate observations, found that unusually high volume tended to precede price moves about 18% larger than that stock's normal moves. It did not, however, tell you which direction the move would go. Heads or tails, roughly. This finding came from stocks specifically, but the underlying mechanism — a volume spike reflects a temporary surge in disagreement or urgency among traders, which tends to produce bigger price swings soon after — has no obvious reason to stop working at the border of an asset class. We simply have not run the same rigorous test on crypto and commodities yet, so we say so plainly rather than assume it carries over.

This is also why a high "activity score" — like copper's 89 out of 100, or Exxon's 61 — is not a buy signal, a sell signal, or a prediction dressed up in a number. It is a measurement of how far outside normal something looks right now, nothing more. Before trusting any signal, on any asset, it is worth understanding the difference between "interesting" and "actionable." Our guide on how to evaluate any market signal before you trust it walks through exactly that distinction.

#Momentum, the concept, versus Momentu, the tool

One last point of confusion worth clearing up. "Momentum" as an investing idea — the tendency for assets that have been rising to keep rising for a while, and vice versa — is a well-studied phenomenon with a long academic history, and it applies across stocks, commodities, and crypto in different documented forms. Momentu the service is not a momentum strategy. We measure unusual activity, not price trend persistence. If you want to understand momentum investing properly, including its real track record and its real limits, our complete, evidence-based guide to momentum investing is worth your time. Just know it is a related but separate idea from what shows up in your daily Momentu readings.

None of this tells you what Chevron, copper, or Bitcoin will do tomorrow. It cannot. What it can do is show you, honestly, when something is moving further from its own normal than usual — and let you decide what, if anything, that is worth to you. If that sounds like a useful habit rather than a promise, our free daily radar is a low-effort way to see it in action.

Momentu is an informational tool, not financial advice or a buy/sell recommendation, and it does not consider your personal circumstances. Any decision you make is your own.
