What a split changes
A 2-for-1 split doubles share count and roughly halves price per share. Ownership percentage is unchanged.

Ranking glossaryWhat every sorting label means+
- Rank by
- Reorders every filtered row using the selected metric.
- Confidence
- Evidence strength from High to Review—not a rating of the company or investment.
- Market cap
- Company size: current share price multiplied by total shares outstanding.
- Index weight
- The security’s percentage share of the S&P 500 in this research snapshot.
- A–Z
- Sorts by company name; select again to reverse to Z–A.
- Split count
- Number of recorded split events in the displayed event history. Partial histories are flagged.
- Share price
- The split-adjusted price of one current share on 24 July 2026, in USD.
- IPO price
- Raw per-share offering price at a comparable, sourced IPO; not adjusted for later splits.
- Listing date
- Month and year of the comparable IPO or relevant listing-lineage event.
- Per-share price ÷ IPO
- Today’s per-share quote divided by the raw IPO price. Because the share units differ after splits, this is not total return.
- IPO growth
- Change from the IPO price to the reconstructed value of one original share, excluding dividends.
- ↓
- Descending order. ↑ is ascending and ↕ means the column can be sorted.
- Original value
- Current price × cumulative split factor, or the current value of a verified successor-share basket.
- Split factor
- How many current shares or successor units one original share became. ≈ marks a reported rather than exact factor.

Provenance
No split found0 filtered rows separated from the original-share leaderboard+
These rows use a provisional 1× factor because the current evidence pass found no split. They are searchable and sourced, but “no event found” is not the same as an issuer-verified never-split history.

Bounded evidence loop
A number stays only when its path survives checks.
Each pass resolves the security, retrieves evidence, extracts typed corporate actions, calculates an exact product where possible, challenges conflicts and records the decision. Unsupported changes are rejected; unresolved candidates remain visible.
“I care less about a spectacular number than whether another person can reproduce it. NeverSplit treats every figure as a claim with a lineage, not just a cell in a table.”

About the project
Built to make financial claims inspectable.
NeverSplit is an independent research project by Leath Al Obaidi, an economist working in regulatory finance. It began as a stock-split question and became a test of how financial claims should be built: resolve the security, trace its corporate actions, calculate the result and preserve uncertainty when sources disagree.
This 503-security S&P 500 snapshot is designed for exploration and verification—not investment advice.
Split mechanics
The pizza does not get bigger.
1 share
→4 shares
Same company value. More pieces. A lower price per piece.
What original value means
It is the current value of all descendant shares from one starting share—not a tradeable quote.
Why lineages matter
Share-class restructurings and spin-offs can require a successor basket rather than one multiplication.
What reverse splits do
They reduce share count and are preserved as exact fractional factors when the evidence supports them.
