It's going to get worse before it gets better.

That might not be the unanimous view on Wall Street, but it feels close to it. Experts are warning that the historic late March rally, which technically took the Dow Jones industrial average into a new bull market, won't last and isn't the beginning of a real recovery from the even larger drop that preceded it.

They're pointing to a variety of reasons, but one of the most popular explanations is this chart. It compares the February and March sell-off, and the recovery after the government adopted a $2 trillion economic relief package, to market performance after the US government passed the Troubled Asset Relief Program that bailed out the banking and housing sectors in September 2008.

If a picture is worth 1,000 words, all of these words would be bad.

RBC's Lori Calvasina says that so far, the market's dive in February and March looks a lot like its late 2008 sell-off.

In spite of TARP and stimulus measures, and other attempts at market rallies, the S&P 500 fell 46% over the next 18 months. Combined with its previous 2007-08 losses, the index fell 57% from its 2007 high point to that March 2009 low.

But there's more to learn from market history than that. Here are the writings of six market experts who think investors shouldn't get too attached to their recent gains - and just as important, what they should do to succeed during the turbulence that's ahead.
