Given the upcoming UK election and the optimistic outlook on Bunzl (BZLFY) following its upgrade to a Buy rating, I anticipate a potential overvaluation in the stock as market sentiment shifts. Therefore, I see an opportunity to short BZLFY, expecting a decline in the near term.

Given the recent upgrade to a Zacks Rank #2 (Buy) and the positive market sentiment following the anticipated Labour Party victory in the UK, I believe BZLFY is poised to benefit from improved economic conditions and investor confidence, making it an attractive long-term investment.
