Two-price share-position arithmetic
Uses only historical or hypothetical values you enter. It fetches no market data, identifies no security, issues no signal and sends no order.
Illustrative result ready.
Difference = shares × (second price − first price) + cash distributions − entered costs. It excludes currency effects, tax and corporate actions not reflected in your adjusted inputs. The default is a deliberately negative hypothetical example, not market history.
All investments carry risk, including loss of the full amount involved, and may not suit everyone. Historical prices, distributions and percentage changes do not indicate future performance. This page does not identify what anyone should buy, sell or hold.
A useful way through this page
- Confirm the company, counter code, currency and quote timestamp on SGX.
- Enter your own purchase and comparison prices; this page carries no quote feed.
- Include dividends, costs and corporate actions before interpreting the result.
Where to check the official price
Use SGX Securities Prices for the exchange quote and time or delay label. Use SGX Company Announcements for price-sensitive disclosures. Use the issuer’s investor-relations site for financial statements, presentations, dividend history and annual reports. A search-result snippet is not a price source.
It can mean the price of SGX Limited itself, counter S68, rather than a directory of every security listed on Singapore Exchange. Confirm the company name, counter code and currency before copying a number.
What an SGX quote actually means
The last traded price is the most recent matched transaction. It is not a promise that another buyer or seller will trade at the same number. The bid is what a buyer is offering; the ask is what a seller requests. Their difference is the bid–ask spread.
| Quote field | What to check |
|---|---|
| Counter and code | Confirms the intended security |
| Currency | Not every SGX counter must be quoted in SGD |
| Last price | Most recent matched trade, not guaranteed execution |
| Bid and ask | Displayed prices on each side of the order book |
| Volume | Amount traded, which helps interpret liquidity |
| Timestamp or delay | How recent the information is |
Price per share alone does not measure company valuation. It must be read with the number of shares outstanding, earnings, cash flow, debt, distributions and the rights attached to the security.
Identify the security before copying a number
This site deliberately has no list of “popular”, “best” or selected shares. On SGX, record the exact issuer, counter code, security type and trading currency from the exchange screen; then match any event to the issuer’s announcement filed through SGX.
| Identity field | Why it matters |
|---|---|
| Issuer and counter code | Prevents confusion between similar names or different listings |
| Security type | Ordinary shares, preference shares, REIT units, ETFs and warrants carry different rights |
| Trading currency | A Singapore listing is not necessarily quoted in SGD |
| Timestamp and delay | Shows when the displayed observation applied |
| Announcement link | Provides the primary record for distributions and corporate actions |
Use the whole period, not only the price difference
In the deliberately hypothetical default, 100 shares move from S$31.20 to S$28.50, a negative S$270 price difference. Cash distributions of S$1.20 per share add S$120; entered costs of S$10 at each observation leave a negative S$170 difference, or −5.43% of the S$3,130 first cost including entered costs.
The distribution input means cash per share over the exact measurement period. The percentage is not annualised and says nothing about a different security or future period. A special distribution can also make one interval unrepresentative.
Why a chart and an account statement can disagree
A historical chart may be adjusted for a split, consolidation, rights issue or another action while an account records actual transactions. A price can also move mechanically when a security trades ex-dividend. Before explaining a sudden movement, open the SGX announcement and check the ex-date, record date, payment date, amount and currency, plus any change to counter code or share count.
A dividend is not free money added without consequence. Other things equal, price can adjust when the entitlement separates from the share.
Reading a normal Singapore trading day
| Market phase | Normal-day timing, Singapore time |
|---|---|
| Opening routine | 08:30–09:00 |
| Morning trading | 09:00–12:00 |
| Mid-day break and routine | 12:00–13:00 |
| Afternoon trading | 13:00–17:00 |
| Closing routine | 17:00–17:06 |
| Trade at Close | 17:06–17:16 |
During SGX auction routines, one equilibrium price is computed. The first criterion is maximum tradable volume; imbalance is considered if more than one price shares that maximum. Random endings apply to parts of the process. Half-days and holidays differ, so the current SGX calendar and notices prevail.
A short market-structure history
| Date | Official milestone |
|---|---|
| December 1999 | Singapore Exchange was formed |
| November 2000 | SGX listed on its own exchange |
| 3 June 2019 | Trade at Close began; normal-day orders in that phase match only at the closing equilibrium price |
| 2025 | MAS announced measures following its Equities Market Review |
Methodology and limits
Prices and trading status belong to SGX. Disclosures come from SGX announcements. Accounts and distribution records are checked against issuer investor-relations pages; historical market totals come from MAS. We do not scrape a quote stream, construct an unofficial ticker or rank shares.
The calculator performs arithmetic on user input only. This page supplies no tradable quote, signal, personalised analysis or order route and does not recommend, execute or arrange an investment.
