The results for March 1st dropped the stock price from around $52 to around $45. That's a 13.46% drop.
More bad news to be expected in the year as Oracle's news was that cloud growth will continue to slow.
So, suppose the stock drops the same amount each quarter, as I don't think the news is not going to get better as the year progresses. Assuming little change during the quarter and applying a 13.46% drop after bad news is announced at the end of each quarter we would have:
June 1st - drop from $45 to $38
Sept 1st - drop from $38 to $32.88
Dec 1st - drop from $32.88 to $28.45
This would not surprise me at all. Decimation of the existing sales teams as well as Oracle's poor ability to execute on their cloud promises, could cause bad results quarter by quarter.
