In August, Nvidia stock soared to all-time highs after the company reported quarterly results. Tuesday's trading in the T-Rex NVDX reflects underlying optimism that Nvidia will deliver another blockbuster earnings report after the market close. Although its price has fallen, reflecting the decline in Nvidia's shares, trading volume has soared to 86 million shares, compared with an average of 26 million. On Wednesday morning, traders will be trading the ETFs based not on the immediate response to the earnings but on Wednesday's activity. "We've seen a 400% jump in average daily trading volume on the day ahead of and following Nvidia's earnings releases," he added.
