Never forget, also during the earnings season: stock prices are a function of demand and supply. When the market already expected the good results, demand may not increase. If expectations were even higher, demand will drop and supply will potentially increase -> stock price will drop.
Also: demand is driven by expectations of future performance. Earnings are a thing of the past, so most investors are interested in the outlook or guidance. Maybe the company dissapointed with their projections for the next quarters?
What may help in the future is to check analyst estimates. Not only the consensus, but the full range. If earnings come in significantly higher than the highest estimate, then you could say there's a real surprise that may drive demand / prices higher. If earnings come in slightly above consensus, the market already expected the numbers and thus there is more needed to drive demand higher (for instance an increased outlook that is higher than analyst estimates for that period).
Edit:
A number of financial sites publish analyst estimates, for instance Reuters. See for this particular company:

I guess 'significantly higher' is a bit subjective and depends on the type of company. But generally, if the range of estimates is quite tight, you need less to surprise the market than when the range is wide.
