BofA: 'SELL-SIGNAL TRIGGERED'

In a note to clients this morning titled "Sell-Signal Triggered," BofA Merrill Lynch strategist Michael Hartnett says flow signals are now pointing to a decent-sized sell-off.

According to Hartnett, last time this signal was triggered, in January 2011, an 8 percent correction in global stocks followed over the course of February and March.

Hartnett writes, "On average, a 'sell' signal precedes a 5 percent correction in global stocks over the subsequent 4-5 weeks."

We've seen a lot of similar calls from other strategists in recent days. Citi strategists, for example, sees these flows as seasonal, which indicates to them that a correction is looming. Read Citi's take here >
