While major US stock market indices are back to new highs and the bull market continues on, there are some well-known large-cap stocks that have been just plain bad recently. We screened the large-cap S&P 500 for stocks that have market caps greater than $20 billion that are more than 20% below their 52-week highs as well as down 20%+ over the last year.  Within the S&P, there are 31 stocks that fit this criteria, which we've called the large-cap "left behinds" in the table below.

You can probably think of a few of these recent "dogs" off the top of your head.  Some of the once-popular stocks that have been left behind include Trade Desk (TTD), Chipotle (CMG), Target (TGT), Schlumberger (SLB), UnitedHealth (UNH), Lockheed Martin (LMT), UPS, and Adobe (ADBE).  This is a pretty diversified group of large-cap stocks covering communication services (TTD), the consumer (CMG, TGT), energy (SLB), health care (UNH), defense (LMT), transports (UPS), and tech (ADBE), but had you built an equally-weighted basket of these names starting a year ago, you'd be down 32%!

If you're a chart-watcher and want to hold down your lunch, don't look at the snapshot below which is another sampling of key names in the "Left Behind" table above.  These down-on-your-luck stocks have been torched recently and most look like they'll never find a bottom.

Of course, the name of the game is to buy low and sell high, right?  We aren't sure which ones will make comebacks, but there will likely be a few that you wished you'd bought when revisiting this list of left-behinds a year from now.
