Banks have come a long way since the financial meltdown, and second quarter earnings showed the biggest sector profit in three years.
Bank scandals are also less common these days.
But analysts are concerned. A team at Piper Jaffray recently studied data from the Consumer Financial Protection Bureau to scrutinize banks with the most consumer complaints per $1 billion in deposits.
They found that banks heavily cross-selling products spur the highest number of customer complaints.
Investors: Keep a sharp eye on these 3 banks. They just might end up on regulators’ radar before too long.
