Imagine that you're an institutional investor and you want to eventually own 500,000 shares of CEPH. Like any investor, you always have the option as to when and at what price you will buy the stock. If the stock is drifting lower, clearly the wisest course of action would be to accumulate the stock on downticks as prices steadily drop. A diversion - Money Flow measures the daily difference between all trades done on downticks and all trades done on upticks. If MF is positive, then there have been more trades done on upticks - negative MF would be just the opposite. Net upticks suggest that buyers have been more aggressive or more anxious to buy - net downticks suggest that sellers have been more aggressive or more anxious to sell. Getting back to the illustration, if you were convinced that CEPH was not going much lower and that it would be much higher sometime in the future, you might be aggressive and buy the stock on upticks, rather than simply accumulate it on the way down. Basically that's the theory behind Money Flow analysis - more specifically, Money Flow Divergence. Divergence works both ways. Positive MF Divergence occurs when prices close lower than the preceding day but MF was positive. Negative MF Divergence occurs when prices close higher than the preceding day but MF was negative. The latter situation suggests that sellers were anxious to dump the stock, believing that prices wouldn't go much higher and were ultimately going lower. This psychological theory doesn't have much relevance unless the divergence persists for an extended period of time - such as CEPH, which today recorded its 11th day -out of 20 - with Positive MF Divergence. Somebody obviously believes that the stock is going higher - at least they're giving clear indications that they're anxious to own the stock. Hope this helps.
