What's going on?

Signify Health�s stock jumped 40% on Monday as a host of buyers think about buying the home-health provider.

What does this mean?

Reports emerged at the start of the month that drugstore giant CVS was interested in buying Signify, which provided in-home healthcare evaluations to around 2 million patients last year. And now it turns out that a handful of other hopefuls have entered the fray, including insurer UnitedHealth, fellow healthcare provider Option Care, and � fresh off its deal to buy One Medical last month � Amazon. There�s no guarantee that an acquisition will go ahead, but the speculation alone is already going down well with investors: UnitedHealth�s reported bid of over $30 a share is almost twice what the company was trading at just a month ago.

Why should I care?

For markets: This won�t be straightforward.
The push for Signify shows how keen companies are to expand into the healthcare industry, which makes sense given that it�s something Americans avoid cutting back on even in a downturn. But a deal in the sector is also bound to catch the attention of regulators, which will be wary that reduced competition could work against consumers. That�s nothing new for the two frontrunners in this particular deal, mind you: UnitedHealth is already fighting to buy Change Healthcare amid concerns that it�ll gain access to sensitive information, while Amazon�s regulatory battles are too many to count.

Zooming out: Amazon goes off.
Speaking of Amazon, the ecommerce giant is thinking twice about its physical stores in the UK. It�s opened 18 checkout-free Amazon Fresh stores across the country, and had plans to open hundreds more. But with the tough economic backdrop having led to disappointing sales, it�s reportedly considering quitting while it�s ahead.
