Short-interest history
FINRA reports open short positions for a settlement date. The publication date is later. These are reported positions, with a separate date for each observation.
Compare the reported short exposure around the dates you bought, sold or watched CSGP. A long position benefits from price rises; a short position benefits from falls. A change in these counts does not predict either move.

Change = this settlement’s shares short − the previous recorded settlement’s shares short; percentage change divides by that earlier count. A zero earlier count has no percentage change. Split-spanning counts are left uncompared. Float percentages use the stored settlement observation, not today’s float.

Dividends and stock splits
See the recorded cash amounts and dates behind CSGP’s income, and the splits that change its share count. Dates below are stored event records, not confirmation of a payment to your account.
Cash-dividend records
No qualified cash-dividend records are stored. This does not establish that the company pays no dividend.
Up to six Polygon cash-dividend events, including recorded ex-dates within the next 120 days. Amounts retain their recorded currency and decimal precision. Historical amounts are not restated to a common split basis, annualized, or converted to dollars.
For a long holding, compare the ex-date with when you held the shares and check the pay date against your broker’s cash history. Owning the stock today does not establish past entitlement. For a short holding, a dividend can create a payment obligation to the share lender.

Split history
10 for 1 · forward split
Effective Jun 28, 2021
Each 1 pre-split share becomes 10 post-split shares.
Source: EODHD
Up to six stored split dates through Nov 7, 2026. Equivalent vendor ratios are combined; conflicting ratios are left out. This history may be incomplete.
A split changes the share count and per-share price basis; it does not by itself add investment value. Put your holding’s earlier and later share counts on the same basis before comparing them. This applies to both long shares and shares owed on a short position.

What it means for you
Sign in to read your holdings or watchlist context. No personal position or direction is inferred.
What happened
Stored recent-activity label: neutral. This context label is separate from the scored insider signal read.
Why it can matter
A count of reported activity describes a sample, not purchase conviction, an insider’s intent or a future price move. Neutral is not an all-clear, and absent direction is not neutral evidence.
How we got this
The current context rule reads at most 50 nonduplicate issuer/share-class records filed in the last 90 days. It counts a bullish direction or purchase code P toward bullish, and a bearish direction or sale code S toward bearish. A side must exceed the opposite count by more than two to set its label; otherwise nonzero directional counts produce neutral. Calculation unavailable for this saved label: its counts, exact records, as-of time and rule version are not supplied here. Do not substitute the separate scored read’s different window or denominator.
Where the data comes from
Stored SEC Forms 3/4/5 insider-signal records, ordered by filing date with amendment duplicates excluded. Filing date is not transaction date. The last-trade line locates recent reported activity; it does not date or reconstruct the complete count.
