Waiting for the voltage drop!! The Tehran Stock Exchange started trading on the last working day of last week balanced but negative with a retreat of 75,000 index units. After the first few minutes the situation gradually improved, and for that matter, the market's central thermometer retraced all of its daily decline. This volatile atmosphere continued until almost 12:00, but in the last half hour the wave of demand strengthened, and finally 71% of the market closed positively, and a growth of 0.5% was recorded for the overall index. The value of the transactions was slightly lower than the last few days and was reduced to 33.6 MET, and the flow of close to a thousand billion tomans in the first half of the market returned in the last hour.
