Wall Street was upbeat last week with the S&P 500, the Dow Jones, the Nasdaq and the Russell 2000 adding about 3.3%, 2.9%, 3.1% and 4.9%, respectively. In fact, the Nasdaq and the S&P 500 rise for fourth straight week.Among the important data points, inflation data was notable. Inflation in the United States moderated slightly as energy and gasoline prices dropped. This is especially true as the consumer price index (“CPI”) jumped 8.5% year over year in July, down from a 9.1% year-over-year increase in June, which was the fastest increase since November 1981.The so-called core inflation, which strips out volatile components such as food and energy prices, rose 5.9% from the year-ago level, in line with June’s gain. Inflation is still near its highest level in four decades and food prices are at the highest annual rate since 1979 (read: Inflation Cools But Food Prices Up Since 1979: ETFs in Focus).The University of Michigan's preliminary August reading on the overall index on consumer sentiment came in at 55.1, up from 51.5 in the prior month. It had hit a record low of 50 in June. American households' near-term outlook for inflation eased again due to falling gasoline prices, a survey released on Friday showed."All components of the expectations index improved this month, particularly among low- and middle-income consumers for whom inflation is particularly salient," survey director Joanne Hsu said in a statement, as published on Reuters.Against this backdrop, below we highlight a few ETF areas that topped last week.ETFs in FocusBitcoin Miners Valkyrie Bitcoin Miners ETF WGMI – Up 22%Viridi Bitcoin Miners ETF RIGZ – Up 20.3%VanEck Digital Assets Mining ETF DAM – Up 18.1%Global X Blockchain ETF (BKCH) – Up 16.7%VanEck Digital Transformation ETF (DAPP) – Up 15.6%Shares of the largest US cryptocurrency exchange jumped as much as 44% last week, the most intraday since its 2021 direct listing, after announcing a partnership with BlackRock Inc. to help institutional investors manage and trade Bitcoin, per Business Standard.
