Dividend payment dates/reinvestment2 Apr 2018 03:15
All brokers have their own/different systems for processing the incoming dividends into your accounts. Some of these systems produce better (more prompt) payments than others.
If you are reinvesting into the same companies shares (ie RDSB dividend is use to buy RDSB shares) then this may or may not be an issue. Generally though ... the market makers are no fools and they know that a substantial amount of the dividend will end up reinvested in RDSB, either automatically or by habitual reinvestors. So, would you believe it, on payment day, and the next 2-3 days, they increase their price/spread to maximise their profit.
Bit like the price of sprouts always goes up as Christmas approaches.
So, don't sweat over a day or two ... take the wiser approach and hold the cash for a while ... then invest either in a different, non-time shifted/manipulated share, or wait for a localised dip and buy back in.
Set a limit order to do the work for you ... choose the price from a day or two before the payment date ... you'll get it, but it might take a week or so.
Best of all ... get yourself a broker that a) handles your dividends well, and b) operates a 'bulk-trade' reinvestment service at super low rates ... (look at iWeb).
