Try this on big names which mostly beat analyst estimates

Buy stocks or call options slightly out of the money 2 to 1 to 2 weeks before earnings. Usually as it moves nearer to earnings, the stock will soar if not impacted by macro news. exit your positions for profit 1 or 2 days before earnings. usually you will see some profit.

for those who intend to hold beyond earnings. eg buy 5 options and exit 4 for a profit and this will reduce your loss as you keep 1 call option.
