David created an ASX meme stock performance index that tracked comments on Twitter and Facebook about Australian listed companies.
The index fell 75 per cent from its peak in 2021.
“It was a real craze, and it was driven by speculation,” he said.
One stock included in the index was the buy-now, pay-later company Zip Pay. Its share price peaked at A$12.35 a share in 2021, but had since fallen 95.6 per cent to be worth 54 Australian cents a share on March 28, 2023.
“Put your belts on, Zip is about to take off,” a social media thread said about the stock, according to David’s research.
One stock David previously shorted through the fund was a lithium technology start-up company called Novonix.
It hit an A$5 billion valuation at its peak while posting no profits, before falling 90 per cent, he said.
“Companies that have really extreme valuations, where no profits end up eventuating, get marked down, because of the mismatch,” David said.
