The major averages are coming off their worst week since October as a retail trading frenzy spooked investors, and Morgan Stanley believes there's more downside ahead.

However, the firm doesn't believe the market is in a full-fledged bubble.

"We don't think the correction is over until leverage is reduced further by both institutional and retail investors," Michael Wilson, Morgan Stanley's chief equity strategist, said in a note to clients.

"While this correction is likely to get worse and feel bad in the short term, this is not a bubble or like 2000 for many reasons," he said.
