Fundamentals Are Strong, page-225

What I will say pretty much applies to 70-80% of the cases, when a share prices falls dramatically in a short space of time it's like an elastic band, will eventually bounce back to the norm even for the worst companies out there, the new normal is discover during an announcement, but regardless of bad or good announcement it will overshoot up (if bad announcement and the market has already priced for the worst it will go green, for good news i should not need to explain) for 3-4 days and fall back to the new normal, if good news over the next month or two you will see it climbing steadily, but if bad news it will be higher than the last monthly low but lower than the new high reached after announcement. The safest bet is always looks for cheap companies in industry when it is falling while others are not, with a few weeks (2-3 weeks until next announcement) buy on the rumor and sell on the news for quick gain, this can be anywhere between 5-30% from the low.
