Every time after ER, spwr always goes down. If the rev below and ER in line, that signals higher gross margin. They beat their own estimate every time, the management is just trying to set low bar so that they can easily beat the expectations.
I do not understand what they are trying to accomplish by doing so. That's why the share price is stuck in low 30's for over 6 months because every quarter they talk down their earnings and then beat it and then again talk down next quarter. I do not think this is a prudent strategy. It just leads to stagnant stock price and P/E ratio compression
