Tuesday, chipmaker Xilinx (XLNX) announced that it was cutting its current-quarter (third quarter) revenue forecast thanks to weaker-than-expected sales to some of its larger communications customers. This announcement comes during a series of quarters in which the company has seen record sales, thanks to rising demand stemming from a perceived economic rebound.

One analyst calls this news, "evidence of a cyclical inventory correction that we'd been expecting and have talked about previously." Nevertheless, the same analyst said that it could take longer than Xilinx had previously estimated for inventory to come back to better levels.

The Street.com's Jim Cramer says that it's too soon to think about selling the semis, the PCs, the components, the DRAMs.

When do we sell the semis? The DRAMS? The flash? When do we get out of the hard drives?

These are legit questions, but the people who are asking, "When do we sell Micron (NYSE: MU) (Cramer's Take), Western Digital (NYSE: WDC) (Cramer's Take) and SanDisk (NASDAQ: SNDK) (Cramer's Take)?" are the very people who told you never to own them.

That's the conundrum of this semi cycle and PC cycle. Just as we are finally hitting our stride and we realize that the semi cycle is alive and well again, AND NOT JUST RE-STOCKING, all over the papers, including the Wall Street Journal, we see reports crying, "When do we sell?"

The chip sector is pretty hot. Intel (NASDAQ: INTC) reported a respectable quarter this week, and the stock is near a 52-week high. Also close to their highs of the year are Texas Instruments (NYSE: TXN) and Advanced Micro Devices (NYSE: AMD).

Well, you can add Xilinx (NASDAQ: XLNX) to the list. The company, an expert on programmable logic, reported an earnings-beating quarter yesterday after the bell, according to Reuters. Xilinx made 23 cents per share in Q2, a penny ahead of analyst expectations. Revenue likewise was slightly ahead of the projections.
