Kind of, not really. It's more like the contraposition.

From what I understand, DCA is buying a fixed amount at a regular interval while DVA is buying up to a fixed amount depending on the portfolio value and a target value. If the portfolio value is greater than the target, one might even sell. The major difference between DCA and DVA is that with DVA you end up spending less $ to reach your target portfolio value if price goes up. Otherwise they are the same.

If you have a hard cap to your portfolio value, DVA should bring the average buy-in price down over time.
