I don't care to try to predict if we're heading into recession or how bad that recession will be. I have no idea where the market will bottom or how long it will take to get there; the one thing I do know is that stocks are going to continue to get wrecked, whether or not we have a short-term bounce. Amazingly, it's been just eighteen days since I warned investors the market would drop 10% in 2008 and now we're already there. I've considered buying quality growth stocks like Mosaic (NYSE: MOS), Monsanto (NYSE: MON), Sigma Designs (NYSE: SIGM), Priceline (NASDAQ: PCLN), BE Aerospace (NASDAQ: BEAV), Vistaprint (NASDAQ: VPRT) and Lululemon (NASDAQ: LULU) on weakness, but their continued downtrending has made them falling knives, aka, too unpredictable for me.

My fellow blogger Lita Epstein has talked about picking up bargains on beaten stocks with strong fundamentals. I disagree with her. While maybe her statement applies to a precious few like Apple (NASDAQ: AAPL) and Amazon.com (NASDAQ: AMZN), I don't care how great those companies are, we're looking at a housing collapse and a massive slowdown in consumer spending which will hurt even the best of companies. For now, forget about stock picks; this is not the time for speculation. If foreign stock markets have tanked this hard on U.S. recession fears, imagine how hard U.S. stocks will get hit -- why not protect yourself and respect the downside for once?

After nailing the top in Apple (NASDAQ: AAPL) and warning investors this would be a painful year, I've been getting hundreds of emails from people asking me what to do next? As if suddenly after two correct predictions, I'm Nostradamus or David Blaine!

Make no mistake, I'm neither a forecaster nor a magician, I'm just a trader who bases his decisions around these key elements: a distrust of everyone and every company on Wall Street (made easier by the likes of MBIA (NYSE: MBI), E*Trade (NASDAQ: ETFC) and Countrywide Financial (NYSE: CFC); a respect, bordering on religion, for charts and a quick trigger finger if the charts turn against me. I know people want longer term predictions, but I believe those to be 100% guessing games and potentially hazard to your investment health. Pregnant women should avoid them at all costs. Just kidding, it's fine for some people, but I like to make my predictions and cash out, so I can enjoy stress-free weekends if you catch my drift.

So, here's what I see right now: two weeks in and we're already halfway to my 10%-down market prediction, and Apple is down 15% (take that you stereotypical cheerleaders, go date some football players)! The markets are definitely rolling over, and while it's usually a long, drawn-out process, the charts seem to have little concern for what's normal as all the major indices have formed perfect head-and-shoulders patterns (a very bearish sign) and investors are rightfully freaking out.

Here are a few highlights of this past week's earnings coverage from BloggingStocks:

Sigma Designs (NASDAQ: SIGM) develops and markets high-performance system-on-a-chip semiconductors for Internet Protocol set-top boxes, DVD players/recorders, high definition TVs, digital media adapters, portable media players and ultra-wideband connectivity products. The company also offers engineering support services and customized chipset development. It has alliances with a variety of well-known tech names, including Cisco Systems (NASDAQ: CSCO), Microsoft (NASDAQ: MSFT) and Alcatel-Lucent (NYSE: ALU).

Sigma Designs surprised the Street last week, when it reported Q3 EPS of 79 cents and revenues of $66.2 million. Analysts had been expecting 55 cents and $51.8 million. Management also guided Q4 revenues to about $72.8-$76.1 million ($54.76M consensus). RBC Capital Markets upgraded the shares to "outperform". Six other brokerages reiterated recommendations of "buy" to "strong buy". All seven firms boosted their price targets to points in the $75-100 range.

"I use the term 'blowout' very sparingly," says tech expert Paul McWilliams in his Next Inning newsletter, which focuses solely on technology investing. "But even 'blowout' falls short of describing the quarter turned in by Sigma Designs (NASDAQ: SIGM)."

Indeed, the advisor notes, "I've likely described something as a 'blowout' less than ten times in the past five years. These 'waterfall' quarters don't happen often. As for Sigma, I didn't see this one coming and it's time to fix it.

"As background, SIGM makes media processor SoC (System on Chip) solutions for STB, BluRay and HD DVD, TV and various consumer devices that benefit from hooking into an IP video network.

"IPTV is an IP video network and, as a result of IPTV, we are putting these sorts of video networks in our homes. Roughly 77% of SIGM's sales last quarter were into IPTV STB applications.

"To give you an idea the magnitude of this recent surprise, SIGM's revenue for Q3 of this year (the October quarter) is closer to the forecasts most analysts had for Q4 next year than it was to what they were forecasting for the quarter just closed.
