Sometimes the price does lag behind longer than expected. Very normal. I was in a stock with a PE of 6. It was a no brainer that PPS would double.
After waiting for months when it moved sideways, lot of investors sold within the 3 to 5 month period.
After 7 or 8 months, it moved up 1.5 times. Then after another 5 or 6 months it doubled again.
This stock will move. If you think Snakes and Latte is growing and NSI and Morning will make a difference, just hold. The wait period is excruciatingly painful but very rewarding. All JMHO!
