First Data's (FDC - Get Report) stock has been on a hot streak this year, up a cool 36%.

The company's business model has a lot to do with the move, explains First Data chairman and CEO Frank Bisignano to TheStreet. First Data is capitalizing on strong growth in e-commerce transactions and the appetite by companies to prevent fraud. With several recent acquisitions now in the fold, debt levels falling and free cash flow rising (raising the prospect for more deals), it's hard to see what will knock down First Data's stock.

Bisignano says rhetoric around trade hasn't weighed on the company's business, despite a good chunk of business being down in Asia and Europe.

Bisignano spoke to TheStreet on Tuesday at the 2018 KBW Community Bank Investor Conference, held by parent company Stifel Financial (SF - Get Report) .
