weighted average price financial

"The price reported is a weighted average price."

Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.

Tel Aviv Stock Exchange market

"These shares were sold on the Tel Aviv Stock Exchange in New Israeli Shekels"

The Tel Aviv Stock Exchange is Israel’s main marketplace where stocks, bonds and exchange-traded funds are bought and sold, providing a centralized place for investors to trade ownership in companies and government debt. It matters because it sets real-time prices and liquidity for Israeli securities, offering a barometer of the country’s corporate health and giving investors a way to enter or exit positions much like an auction house or farmers’ market sets the price for goods.

exchange rate financial

"The exchange rate in effect on the transaction date was 3.023 ILS to $1.000"

Exchange rate is the price of one currency expressed in another—for example, how many euros you receive for one US dollar. It matters to investors because changes in that price alter the reported profits, costs and value of assets for companies and portfolios that operate or hold money across borders; think of it like switching measurement units, where the same item can look bigger or smaller depending on the unit used.
