Alpha
In simple terms
Alpha is special information about a cryptocurrency or investment that most people don't know yet. If you find out about a big company partnership before everyone else, that's alpha—it gives you an advantage to make a profitable trade.
Definition
Valuable or insider-like information that gives a trading edge.
In depth
Alpha refers to excess returns or informational advantages derived from proprietary analysis, market microstructure insights, or early access to on-chain data and fundamentals. In crypto trading, alpha sources include monitoring mempool activity, tracking whale wallet movements via blockchain explorers, analyzing token unlock schedules, or accessing early announcements before they propagate across price-discovery mechanisms. Strategies that extract alpha typically rely on information asymmetry—exploiting the lag between when information becomes available and when it fully reflects in market prices across decentralized exchanges and centralized venues.
How does Alpha work?
Alpha began as a measurement. Take a portfolio's return over a period, compare it with a benchmark's return over the same period, and adjust for how much of the move simply came from the benchmark — that sensitivity is beta. Whatever excess is left, positive or negative, is alpha. It is calculated after the fact, and fees, funding costs and slippage come out of it first. In crypto slang, alpha instead means information not yet widely known. Its value comes entirely from being early, so it decays as it spreads.
An example
Illustrative: a portfolio returns 30 percent over a year while its benchmark returns 25 percent, and it moved roughly one-for-one with that benchmark. The gross excess is 5 percentage points; after 2 points of fees and trading costs, measured alpha is about 3 points. One year of data cannot separate skill from chance — gaps that size arise regularly from randomness across a large number of portfolios.
Figures are illustrative only.
What beginners get wrong
- A positive return is not alpha; if the benchmark rose more over the same period, the result trailed it despite being profitable.
- Paid alpha groups and signal channels sell information to a crowd, which is the point at which any informational edge has already gone.
- Alpha calculated before fees, funding and slippage is overstated, and those costs are frequently the entire difference.
- Extra return earned by taking more risk or more leverage is exposure, not alpha, though it is often presented as skill.
