David A. Miller is CLO & VP +1 at T-Mobile US, Inc. (TMUS). They have made 22 open-market trades across 2 companies since 2010, most recently 2021-08-12.
Unrated. We grade insiders only on stock they chose to buy on the open market. Grants, option exercises and vesting say nothing about timing, so they don't count — which is why someone can file often and still have no grade. It isn't a bad sign: unrated buys beat every graded tier below A.
4 open-market purchases totalling $8K since 2010, against 18 sales. Too few scored purchases to measure a record yet.
