On Friday, July 21st, a total of 68.4 million options contracts were traded, resulting in a net growth of 8.04 million calls and 7.10 million puts. This significant trading volume was driven by increased interest in several key stocks, with NVIDIA (NVDA), Tesla (TSLA), MicroStrategy (MSTR), and Opendoor Technologies (OPEN) seeing the greatest growth in open interest [3].

The top five new positions opened on July 21st included:
- 99,000 Tesla (TSLA) 7/25 weekly 100 puts,
- 64,000 Marathon Patent Group (MARA) 7/25 weekly 21 calls,
- 52,000 Plug Power (PLUG) 7/25 weekly 2 calls,
- 41,000 Core Scientific, Inc (CORZ) Aug-25 9 puts, and
- 39,000 Core Scientific, Inc (CORZ) Aug-25 18 calls [3].

The surge in options activity reflects investor optimism and speculation about the future performance of these companies. For instance, Tesla's 7/25 weekly 100 puts suggest that investors are positioning for a potential downturn in the stock price, while the high volume of calls on Marathon Patent Group and Plug Power indicates bullish sentiment [3].

Opendoor Technologies (OPEN) has been a notable performer, with its stock surging 180% in the past week following a bullish post by Eric Jackson, head of EMJ Capital [4]. Jackson shared a turnaround thesis for the struggling company, placing a long-term price target of $82 per share. The recent rally has been attributed to several factors, including positive Q1 2025 financial results, a strategic build-up in inventory, and expansion of its agent partnership program [4].

Plug Power Inc. (PLUG) also witnessed significant stock price appreciation, rising 8.48% on Friday, as investors anticipate growth in the fuel cell market [5]. The company is expected to benefit from the market's expansion, supported by continuous artificial intelligence advancements in energy delivery.

The increased options activity and positive stock performance reflect a broader trend of investor confidence in the technology and renewable energy sectors. As these companies continue to innovate and adapt to market conditions, investors will closely watch their performance in the coming quarters.
