We've pinned down the ever-dancing Wall Street Warrior Timothy Sykes for another StockWatch: Between the Bells segment! In this edition, the author of An American Hedge Fund: How I Made $2 Million as a Stock Operator & Created a Hedge Fund cautions you to revise your strategy for the developing bear market. "It is not the time to be aggressive, it is the time to be conservative," says Tim.

We're probably in a bear market now, Doug McIntyre says in the latest edition of StockWatch: Between the Bells. The editor of financial news site 24/7 Wall St. and prolific BloggingStocks contributor cites two factors that demand investors' attention: the rising, record price of oil -- underscoring the falling value of the dollar -- and an increase in homeowners defaulting on their mortgages in the coming year.

Ready to make some serious money? Wall Street Warrior Timothy Sykes isn't playing around -- he wants to make you rich. In this edition of StockWatch: Between the Bells, the MSN Money host and author of An American Hedge Fund: How I Made $2 Million as a Stock Operator & Created a Hedge Fund riffs -- and dances -- on a fistful of market strategies.

Tim has three daring tips for you. Digital content storage provider Isilon Systems (NASDAQ: ISLN) is sitting at an all-time low, more than 70% off its high at the start of the year, and looks priced to buy. Genetics biotech Illumina Inc. (NASDAQ: ILMN) is currently trading around $52; Tim sees ILMN climbing to $60. Sound a little too risky? Tim suggests checking out The Bruce Fund (BRUFX), a mutual fund focusing on domestic common stock, convertible bonds and zero-coupon government bonds.

Considering a short-selling strategy? Tim calls out China Precision Steel (NASDAQ: CPSL), which has jumped more than three-fold in little more than a week and looks set to slide.

Jamba Juice (NASDAQ: JMBA), meanwhile, is giving Tim fits -- revenues are up while same-store sales are slipping. He advises to stay away from JMBA.
