Although inflation remained a point of concern for many investors last month, a sharp pull-back in 10-year Treasury yields helped support tech stocks, with growth names outperforming value plays. The Nasdaq leapt 5.5% in June, compared with a 2.2% rise for the S&P 500 and a 0.1% decline for the Dow Jones.

The Federal Reserve accelerated timeline for the first interest rate hikes did little to deter investors who instead took confidence in the economic recovery unfolding across the US and Europe amid successful vaccination campaigns.

What US shares were Selfwealth members trading last month? Let take a look.

Which US shares were the most held?

AMC Entertainment (NYSE: AMC) was last month biggest-mover, jumping into fourth place as the Reddit-inspired short squeeze from late-May continued to flourish. In the end, AMC shares soared 117%, although holdings across the Selfwealth community grew by 157% as the rally prompted a number of new investors to pour into the stock.Despite being well off its highs, the beaten-down share price of Alibaba (NYSE: BABA) resonated with some long-term investors, with the stock now edging ahead of Berkshire Hathaway (NYSE: BRK) into 11th position. Alibaba shares have been under pressure ever since the business came under the scrutiny of Chinese regulators, and more recently, after posting its first quarterly loss as a public company.In what is overwhelmingly still a tech-dominated top 20 list, Uber (NYSE: UBER) joined the fold, finishing in 15th position among the most-held US shares. Uber shares actually slipped 1.4% in June, and have largely been consolidating for the best part of six months, but the company has a small base of supporters across the Selfwealth share trading platform.Chip-makers and electric vehicle production remain popular investment themes across the Selfwealth community, with names like Tesla (NASDAQ: TSLA), Nio (NYSE: NIO), Nvidia (NASDAQ: NVDA) and Advanced Micro Devices (NASDAQ: AMD) entrenching their popularity by way of strong double-digit growth in shareholdings.US StockCompany1GMEGameStop2TSLATesla3AAPLApple4AMCAMC Entertainment5ARKKARK Innovation ETF6AMZNAmazon7MSFTMicrosoft8PLTRPalantir9NIONio10ARKGARK Genomic Revolution ETF11BABAAlibaba12BRK.BBerkshire Hathaway13GOOGLAlphabet Class A14UBERUber15ARKFArk Fintech Innovation ETF16NVDANvidia17AMDAdvanced Micro Devices18QQQInvesco QQQ Trust Series 119GOOGAlphabet Class C20SQSquare

US share trading activity

For the second month in a row, the value of shares traded in Nio (NYSE: NIO) eclipsed all other US stocks, even though there were just shy of 150 trades across the month. It was one of only a few stocks among the most actively-traded names that had a greater proportion of selling activity than buying, although significant trade sizes meant it was still the most-bought stock by value too.Stocks that are popular within the Reddit community continue to draw interest among Selfwealth members, and it wasn't just the well-known stories of GameStop (NYSE: GME), AMC Entertainment (NYSE: AMC) and BlackBerry (NYSE: BB).Instead, amid hopes of short squeezes, and as FOMO transpired into gains, there were strong trade numbers in stocks such as Churchill Capital Corp IV (NYSE: CCIV), Clover Health Investments (NASDAQ: CLOV), Naked Brand Group (NASDAQ: NAKD), Workhorse Stock (NASDAQ: WKHS) and Corsair Gaming (NASDAQ: CRSR) Meanwhile, Israeli business Nano Dimension (NASDAQ: NNDM) was the seventh most-traded stock by value, with shares in NNDM rising 16.1% throughout June. The company, which specialises in semiconductor 3D printing, was a beneficiary of upbeat sentiment for tech stocks, as well as its exposure to the highly-popular themes of additive manufacturing and chip-makers. During the month sentiment was also aided by the company receiving patent approval for double-sided and multilayered printed circuit board fabrication using inkjet printing¯.Further down the list, digital residential real estate platform Opendoor Technologies (NASDAQ: OPEN) gained traction, landing in 14th place and drawing more trading interest than the likes of Amazon (NASDAQ: AMZN). Shares in OPEN performed strongly last month, up 13.2%. Interest in the stock has extended beyond the red-hot housing market, with buyers fond of the company ties to venture capitalist Chamath Palihapitiya, who has had success with SPACs for Clover Health and Virgin Galactic Holdings (NYSE: SPCE).Top 20 stocks traded by valueCode SecurityBuy-sell Ratio1NIONio48.70%2GMEGameStop66.6%3AMCAMC Entertainment62.0%4CCIVChurchill Capital Corp IV49.2%5AAPLApple55.5%6TSLATesla67.6%7NNDMNano Dimension55.2%8CLOVClover Health Investments57.3%9BBBlackBerry50.8%10BABAAlibaba75.6%11PATHUiPath50.6%12UBERUber99.9%13SQQQProShares UltraPro Short QQQ ETF11.1%14OPENOpendoor Technologies49.4%15NAKDNaked Brand Group53.0%16OCGNOcugen48.7%17WKHSWorkhorse Group51.3%18ARKKARK Innovation ETF83.6%19CRSRCorsair Gaming56.5%20AMZNAmazon81.5%
