Overview of the stocks that were traded the most by DEGIRO clients in September 2021.

Most traded stocks September 2021

In the investing world, the September Effect is a market anomaly referring to historically weak stock market returns during the month. Much of this theory is anecdotal, however, the S&P 500 and EURO STOXX 50 ended in the red for the first time in eight months. The S&P 500 and EURO STOXX 50 posted losses of 4.76% and 3.53%, respectively.

In this article, we discuss the companies that made an appearance on the map for the first time and share September’s biggest winner and loser.

Aterian saw the biggest price increase out of the stocks on the map during September.

Newcomers on the map

Three companies made their map debut in September. Below is a brief introduction of each and some information about its stock:

Aterian Inc.

Aterian is a technology-enabled consumer product platform. The company has a cloud-based platform called AIMEE, short for Artificial Intelligence Marketplace Ecommerce Engine, which leverages machine learning, natural language processing and data analytics to streamline the management of products at scale across the world’s largest marketplaces, such as Amazon, Shopify and Walmart. It owns 14 owned and operated brands, selling products in a wide range of categories, from home appliances to essential oils.

Aterian is considered a meme stock, with investors on Reddit’s WallStreetBets forum banding together to drive the price up in hopes of igniting a short squeeze. Similar to other meme-stocks, such as GameStop and AMC, Aterian stock price does not reflect the company’s fundamentals. Instead, it is fueled by social media attention, making it very volatile.

Stock prices in September were up and down in September and ended the month up by 81.81%.

Sphere 3D Corp

Sphere 3D is a cloud-based software provider based in Canada. It has a portfolio of brands, such as HVE ConneXions, Unified ConneXions and SnapServer. Sphere 3D is considered a small-capwith a market capitalisation of around $350 million.

Back in June, Sphere 3D announced a merger with Gryphon Digital Mining, a Bitcoin mining operation using renewable energy, which is set to complete in Q4 2021. On September 15th, Sphere 3D’s stock price jumped by 35% after Gryphon Digital Mining announced that it received a shipment of machines that the company will use to mine Bitcoin in a way that is carbon neutral. At the end of September, prices were down by 8.47%.

Vinco Ventures

Vinco Ventures, which is also considered as a meme stock, is an acquisitions company that focusses on digital media and content technologies.

Vinco Ventures is also involved in non-fungible tokens (NFTs). In September, Vinco Ventures together with its subsidiary Emmersive Entertainment announced that it will be launching the first NFT streaming movie soundtrack with Grammy winners Om‘Mas Keith and Adrian L. Miller. Stock prices were down by 21.35% at the end of the month.
