The S&P 500 Selection Committee might have left us high and dry, but investors need not worry; their friends at Russell FTSE sure won’t.

That’s because June’s real all-star event has finally teed off — the annual Russell Reconstitution, famously one of the most significant market events of the year, with some $19T of assets set to be rearranged across indexes like the Russell 1000 and 2000 (which together make up the Russell 3000).

When size does matter: In a way, Russell Reconstitution is the closest thing that passive, market cap-oriented investors have to a true meritocracy — call it America’s stock leaderboard, if you will. And on Monday, the competitors were set as Russell FTSE finalized its membership list of the 3K most valuable entities in US markets. Many are repeat contenders, but the spotlight shifts to companies rising or falling through the ranks of the indexes like the Russell 1000 (the 1K most valuable firms in the US) and Russell 2000 (the next 2K).

• Businesses have until June 27 to score a spot in one of the two indexes, with firms making the biggest leaps and bounds likely to attract attention as preliminary membership lists are released weekly.
• Special attention will be paid to the breakpoint, the point between large cap (the top 1K) and small cap (the next 2K after that) — in 2024’s Reconstitution, that amount was $4.6B.

The Big Picture

With over 200 additions slated in the Russell 3000, we’ll be taking a vested interest in some of the new entrants, also highlighting companies that made substantial leaps — like graduating from the Micro Cap Index to the Russell 2000 or from the 2000 to the 1000. And when it’s said and done, we’ll digest the big picture: how it reshapes indexes themselves.

• Sprouts Farmers MarketSFM
  , FTAI AviationFTAI
  , and InsmedINSM
  are among the firms at the top of the Russell 2000, looking to leap up.
• Whether the sweeping changes will reignite the particularly stagnant Russell 2000 will also be a theme to watch — it’s up just 5.6% over the past year, compared with the Russell 1000’s 12.5% (which outstrips the S&P 500’s own 12% return).

Nice to knows: This year’s Reconstitution is the first since implementing a new capping methodology meant to meet regulatory requirements by restricting the weight of members. However, it will also be a last — that’s because this is the final time that Russell Reconstitution will be a summer spectacle alone. Starting next year, the index will be shuffled twice a year — both in June and November. The change-up will turn Reconstitution into a bi-annual affair, adding a new holiday surprise for investors.
