It's been a contentious year for the big tech stocks since around early to mid 2022 until present, which make up about a quarter of the S&P500.
From around 2013 to 2020 in particular, you had a huge number of prognosticators, including myself, squawking about how many more tens of billions of devices we will have in the world in the upcoming decades, and how transformative this will be to tech.
So let's really scrutinize these hardware prognostications of the heady Bernankean-Yellenesque, low-interest rate days of the 2010s. Did electronics and IoT really have its day?

The above link shows one ETF that I could find which is IoT-themed, however it seems to highly index the S&P500. Any other suggestions that could plausibly mirror what the IoT are welcome for this market.
Clearly SNSR did not out-perform SPY in this year.
Looking at SNSR vs VOO for maximum timeframe:
SNSR started on Sept 16, 2016 at $15.19 and gained ~120% to date.
VOO was at $195.89 on September 16th, 2016 and went to $437.79, for a percent change of 123%.
So roughly, they were the same and SNSR likely does no more than just track VOO/SPY.
