Roughly $478 the floor for Costco?

I've kept an eye on stocks such as Costco ($COST) ever since the pandemic. Now, with the U.S. economy sputtering and likely already in a recession (based on the definition) I believe low-price, big-box retailers could be a strong bet.

Looking at the trendlines (this is my first time publishing, so be gentle), it looks to me like Costco should hold at or around $478.

I sold off my shares before the dip really began. But, I'm thinking about buying back in and staying long through the recession.

Any thoughts?
