Why Delek Holdings Stock Triumphed on Tuesday
Delek US Holdings (DK) will join the S&P SmallCap 600 index on Sept. 21, replacing Brinker International. The stock rose over 5% on the news, likely due to increased visibility and potential index fund inclusion. The change does not alter the company's fundamentals.
