Key Facts

2Amplify Energy was added to the Russell 3000E Index.

As part of the annual Russell 3000E Index reconstitution, Aligos Therapeutics (ALGS) and Amplify Energy (AMPY) were added to the broad-market index, according to MarketScreener reports. Index inclusions typically attract passive fund inflows and increase institutional visibility, providing a liquidity boost for both stocks.

Following the announcement, ALGS closed at $5.57 (June 26 close), while AMPY ended at $3.94, per market data. Both firms are small- to mid-cap names—ALGS focuses on antiviral therapeutics, while AMPY is a U.S. oil and gas producer. Inclusion criteria are based on market cap and liquidity, enhancing the stocks’ appeal for tracking funds.

In the near term, $5.74 (June 26 high) may act as resistance for ALGS, with $5.30 as potential support. For AMPY, $3.97 is the session high and $3.89 a nearby floor. No direct economic events for these stocks appear in the next seven days per the economic calendar, but broader index moves and U.S. energy data could influence AMPY’s trajectory.
