personally, I think the drop in price is just a reflection to the overall market.
if you look at the S&P/ASX200, it dropped from 47xx to 458x in 2 weeks... (probably some day traders are taking their profit)
As long as the fundamental value of this company remain strong, I believe the share price will raise even higher in the long term.
So... the drop in SP will be a great opportunity to buy for long term investment
