S&P Dow Jones Indices said Five9, Inc. (FIVN) will replace Two Harbors Investment Corp. (TWO) in the S&P SmallCap 600 effective before the Aug. 3 open. The change follows CrossCountry Mortgage’s acquisition of Two Harbors, expected to close soon, subject to final conditions.

The 30-second read
Why it matters
Traders may expect index-tracking and rebalancing flows around the effective date, but the announcement does not include quantitative details (index weight, expected share turnover) to size the move.
Market read
Definitive index inclusion timing for Five9 can drive short-term passive flow effects into and around Aug. 3.
What to watch
Actual impact depends on Five9’s index weight, float, and whether passive managers rebalance ahead of the effective date; the article does not quantify these.
Background
S&P Dow Jones Indices announced a scheduled change to the S&P SmallCap 600, with Five9 replacing Two Harbors Investment Corp. effective before the Aug. 3 open.
Ticker impact
Five9 will replace Two Harbors Investment Corp. in the S&P SmallCap 600 effective before the Aug. 3 open, driving index-tracking flows.
Likely modest, short-term positive bias around Aug. 3 due to forced/benchmark buying, with reversal risk if flows are already priced.
The article is a definitive index-change announcement with an effective date, but it provides no weight, share count, or expected tracking-fund flow size.
Market effects
Small-cap index membership changes can shift relative flows within the broader communications/tech-enabled services cohort, but no sector fundamentals are disclosed.
Primarily US small-cap passive flow impact; no cross-region effects mentioned.
Limited global relevance since it is a US index methodology change.
Counterpoint
If the market already priced the index-change effect, incremental buying into Aug. 3 may be smaller and any post-open drift could be muted or reverse.
