SunTrust's online lending platform doing well - KBW

• Online lending has taken a large black eye of late, but SunTrust's (STI -0.2%) LightStream is a "ray of sunshine" for the bank, says KBW.
• The digital lending division makes loans for just about anything to "super prime" customers - those with FICO scores north of 750. The operation is doing about $1.5B annually, only about 1.5% of all loans at SunTrust.
