Consider the 5 forces of the grocery industry. How does Trader Joe's (TJ) strategy neutralize the threats posed by various industry forces? Please be specific.

Trader Joe's strategy may be categorized as the Blue Ocean Strategy (Integrated Cost Leadership/ Differentiation). Yet, as we mentioned before, many businesses that attempt to pursue this strategy would get "stuck in the middle." Why can TJ achieve both low cost and differentiation without getting stuck in the middle? Please identify one key reason. (Hint: for example, you can consider the trade-offs that TJ made.)
