Just give it a quick google, an unofficial answer put as follow: (hope it helps to other frogs like me )
The terms "accumulation day" and "distribution day" were coined by financial paper Investors Business Daily.
An "accumulation day" is a day in which the major indices (S&P, Nasdaq, etc.) realize a gain AND on higher volume than the previous day. This tells us mutual funds, hedge funds, and other institutions are behind the buying.
A "distribution day" is one in which the major indices realize a loss AND on higher volume. This points to institutional selling.
When one starts to spot "distribution days" in an uptrending market, or "accumulation days" in a downtrending market, it usually is an early warning signal of a potential trend reversal. |
