BREAKING: One of the Biggest Stock Market Crash Indicators Since 2008

We just received one of the biggest stock market crash indicators we've seen since the 2008 financial crisis.

A Bank of America Merrill Lynch note today shows the bank's clients sold more than $4.1 billion in U.S. stocks last week. That's the largest amount in any week since January 2008, according to analyst Jill Carey Hall.

And as this chart shows, most of that selling pressure came from institutional clients:

"After three weeks of net buying, institutional clients' net sales last week were the largest in our data history," Hall wrote in the note. Hedge funds were net sellers for the ninth consecutive week, while private clients bought stocks last week following the previous week's net sales."

Healthcare and financial stocks saw the most selling pressure, according to the bank.

Today's news comes at a time when the broader markets are soaring. The Dow Jones Industrial Average set a record high of 18,351.36 in May and is up 1.7% in 2015. The Nasdaq Composite hit its own record high of 5,163.42 yesterday morning.

That has many worrying that a stock market correction - or even worse, a stock market crash - is on the way.

Here's how you can protect yourself in the case of a stock market crash or correction...

How to Protect Yourself from a Stock Market Crash

Money Morning Capital Wave Strategist Shah Gilani has developed a three-step strategy for profiting during a stock market crash. Instead of panicking and fleeing the markets, he turns the dipping markets in his favor.

Gilani is one of the world's foremost experts on the credit crisis. He not only called for the implosion of the U.S. financial markets in 2008, he also predicted the historic rebound that began in March 2009.

"There are lots of ways to make money when things go down," Gilani said. "But just knowing about the three most popular strategies to play price or market declines is enough for you to cash in on the next stock that plunges on disappointing earnings - or on the next bear market in blue chips."
