The fourth quarter is now off to the races and we thought it worthwhile to check in on the best and worst-performing S&P 500 stocks on a year-to-date basis.  As shown below, there are currently six members of the index that have rallied over 100% this year.  Apt for the year that its vaccine has rolled out, the biggest gainer of these has been Moderna (MRNA) with a 196.12% rally.  It now has a market cap of $124.87 billion versus a market cap of only $41 billion at the start of the year. Of the 20 best performers, MRNA is also the only one with a market cap above $100 billion. The next largest is ConocoPhillips (COP) with a $95.76 billion market cap.  COP is one of multiple Energy stocks on this list as well. Of the top 20 performers, Energy sector names dominate the list with 8 members.

Pivoting to the other end of the spectrum, Las Vegas Sands (LVS) is down the most this year having been cut by 36.18%.  IPG Photonics (IPGP), Lamb Weston Holdings (LW), Viatris (VTRS), MarketAxess (MKTX), and Global Payments (GPN) also have fallen by at least 25%.  Once again, there is only one member of this list with a market cap above $100 billion: Qualcomm (QCOM).  One other interesting factor to note of the worst performers is there are several stocks that were at some point plays on pandemic trends, whether those be reopening or stay at home. For example, in addition to LVS, another gaming/reopening name, Wynn Resorts (WYNN), ranks as the eighth-worst performer YTD.  Additionally, strong performers during the onset of the pandemic like Clorox (CLX), Activision Blizzard (ATVI), and Take-Two Interactive (TTWO) are all down double digits this year.
