That's just good personal anti-business sense: If you're newly appointed to a position with clout, declare some arbitrary change. If random market change favors you, claim your new ideas and thoughts boosted the company. If random market change goes against you, claim market slump AND growing pains from new management shift then claim the recovery as your efforts and achievements.

As a side note, this is why cereal boxes tend to get an arbitrary re-design every so often on some minor aspect that makes no real difference.
