I go for blue chip reputable companies when there is bad news too - sudden dip, get in at the low, sell at profit on gain.
I don’t necessarily wait for dividends either, but will often time my sells leading right up to the ex-divi date (i.e sell at a high price when everyone else is buying just for the divi)
Or buy at the dip after the ex-divi date itself.
if you can gain upwards of 10% to 50% and do it 10 times over with 10 different shares, then you have gained a good lump sum - which is something new to invest, then start the process again.
Have done this for example with Royal Mail, Whitbread, Dunelm - all on bad news, all good gains later.
Also the markets dip each morning at 0830 - I used to look avidly then for the bad news blue chip companies (biggest fallers) and sometimes choose wisely there, sometimes even selling before close the same day.
Trading fees and tax applied to share purchases have to make it worthwhile though…..
Would also not be able to do it in £10 denominations though….
