On the markets organised by Amsterdam Exchanges, August was an extremely hectic month with major price fluctuations. The volatility of individual stocks was reflected in the daily price movements of the AEX-index. Measured in points, the index for the 25 most-traded issues on Amsterdam Exchanges this month recorded both the largest one-day gain and the biggest one-day loss in its history.

In an effort to subdue the volatility of the AEX-index, the financial markets of Amsterdam Exchanges repeatedly invoked what is known as the 2% rule. This rule comes into force when the AEX-index has risen or fallen by more than 2% during a one-hour period. On Friday, 15 August, trading ceased for the day at 16.24 hrs after the AEX-index had fallen by 5% in comparison with the opening level.

AEX-Effectenbeurs

On the AEX-Effectenbeurs heavy trading in stocks and bonds generated high turnover. Total August turnover of stocks and bonds amounted to 20.1 bn, an increase of 26.35% in comparison with August 1996.

Even more remarkable was the substantial rise in the number of transactions by 147.9% to 824,989. The number of transactions on the AEX-Effectenbeurs during the first eight months of this year has risen to 5.7 million, an increase of 78% in comparison with the same period in 1996.

Price moves on the AEX-Effectenbeurs were affected by several factors, including the value of the American dollar and share prices on Wall Street, growing fear of interest rate hikes and by the half-year figures published by many Dutch companies.

The AEX-index sky-rocketed to a record high of 1011.62 this past month, an increase of 52% in comparison with the index's opening level in 1997. However, the index dropped below the 900 level later in the period and closed the month at 868.29.

AEX-Optiebeurs

August turnover on the AEX-Optiebeurs amounted to 4.9 million contracts, an increase of 132% in comparison with August of 1996. Premium volume in the same period rose by 419% by 5.1bn.

During the first eight months of this year, the number of traded contracts rose by 88% to 34 million. Premium turnover in the same period rose by 263% to 83bn.

Individual shares, and hence the AEX-index, experienced substantial price fluctuations. The biggest one-day gain was recorded on 19 August, when the AEX-index picked up 29.97 points in a single day. The biggest loss - 42.64 points - was recorded on 13 August.

As a result of the enormous volatility of shares prices, volatility on the AEX-Optiebeurs rose across the board. The 3-month volatility of the AEX-index climbed from 16.35 on 1 August to 25.12 at the beginning of September. Individual stocks experienced even greater increases in volatility. The 3-month volatility of Hoogovens stocks jumped from 24.92 to 42.27 during the same period.

Volatility is an important tool in determining the theoretical value of options. The more volatile the stock, the greater the chance that an option on the stock will acquire - or lose - intrinsic value.

AEX-Agrarische Termijnmarkt

AEX-Agrarische Termijnmarkt, the agricultural futuresmarket of Amsterdam Exchanges, traded more contracts than in the same month last year, and turnover was also higher than in July of 1997. Total August turnover reached 16,474 contracts.

With a turnover of 13,712 contracts, potato futures were responsible for the lion's share of this total. Here too, prices were volatile as an August heat wave caused the price the potato futures contract to rise by more than 10% on 12 August.
