"Overvalued" or not can also depend on when you enter the market. I suppose it is safe for one to make sure that one always have enough cash Flow, just in case. dont hold on to too many shares at one go, st the expense of liquid cash.
Even with the seemingly-attractive share price, there are red flags in that the balance sheet is negative, and there is not much cash flow. Looking at these "business numbers", so to speak, it would occur to me that it might be better to stay away for now, until there is some indication of improvement for BBBY.
