I'm guessing you figure TTS could be the next LL. However, LL was in a very similar position to LF before its astonishing run. I bought them at $15 when their price to book was in a similar position as LF is now (between 1.0 and 2.0 P/B, TTS is currently priced at greater than 10x book). Unfortunately I sold LL at $25 (still a profit, but man i wish i held on longer).
TTS may be a great store and a great concept, I dont know, but i do know the way its priced they're expecting spectacular growth already. In order to make money TTS would have to experience even more growth than what is already factored in to the price. If that growth doesnt materialize you could be looking at a much lower share price.
I will stick with LF. I hope to see $5 as i will load the truck at that price.
