The reality is that the share market rose by 0.3%, if looked at properly.

Yes, ANZ Bank (ANZ) and National Australia Bank (NAB) did trade ex-dividend today. Last week's post reported on these dividends. The share price of these banks was expected to fall today by the value of the dividends, as a seller of the shares gets to keep the dividends, and a buyer does not receive the dividends.
