Bug: Typing fast fetches the wrong ticker information

If I type a ticker fast and hit return, the system brings up the information for another ticker instead. For example, type TMUS fast and hit return; the page displayed was for TM instead. To overcome this, I have to type and wait for the popup to display the choices and then hit enter or pick from that list and it works, of course. But it is frustrating not so much to wait but because I forget and type fast and not realize that I am on the wrong ticker and then take those numbers and put them in my spreadsheet to calculate things only to realize later that I grabbed info for the wrong ticker.
