start buying in with dca strategy one month before earnings announcement of the stock you are confident with. but do take note that some stocks may already run up to its full potential 1 or 2 days before actual day announcement due to all the hype from the media.
For eg apple, every analyst and news outlet reporting its going to be a great results...so what could possibly happens? many already bought way before actual day and if results is really as expected what's the further upside? there is only more downside should the results not as expected.
