What The Cumulative Volume Index Can Say About Smart Money
The cumulative volume index is an indicator of great importance when trying to suffice the difference between a strong market and a weak one.
One thing that has interested me as related to this indicator is related to the divergences between the CVI and price movement.
Overall, you surely would like the underlying stock to have an overall upwards trending CVI, as this indicates that there is a strong demand for that market and money is consistently flowing into it.
A downwards CVI would indicate that sellers are exiting their positions and have lost faith in the market.
However, with that being said there is something to say about the divergences and convergences of the CVI and price movement.
Key points of rising CVI and falling price:
Accumulation / absorption: Buyers may be quietly absorbing supply on the way down, so the breadth/volume backdrop is improving before price reflects it.
Selling pressure is weakening: The down-move may be running out of fuel (fewer stocks participating on volume), even if the index/price is still drifting lower.
Higher odds of a reversal or bounce: Not guaranteed, but divergences like this often precede a short-term bottom, especially if you later see price break structure (higher high / reclaim key levels).
Key points of falling CVI and rising price:
Rally on narrowing participation: Fewer stocks (or less advancing volume) are powering the move, so the uptrend is more fragile.
Distribution / fading demand: Buyers are still lifting price, but the net volume backdrop is deteriorating—often seen near exhaustion tops or late-stage pushes.
Higher odds of a pullback or reversal: Especially if price is making new highs while CVI makes lower highs.
I believe that this is a macro-level indicator that can provide valuable insights into the overall health of a given market, but in order to trade based off of this indicator at favorable entries it would require other filters and catalysts to time the market more efficiently.
