My take? The strategy is like a contractor fixing up houses. GameStop was the crappiest house on the block. He’s fixed it up and is using it as collateral to take out a loan and buy the dilapidated mansion next door (eBay). He’ll keep going until he’s gentrified the whole neighborhood using the value of the current business as collateral to buy the next. He wants to sell only when the value of the entire gentrified neighborhood reflects market rate for the work he's put in.
