Any uptick a pension fund would have had was lost once GME reverted back.
Pension funds are buy and hold, so they could care less about short term fluctuations in 0.05% of their portfolio.
(Ontario Teacher’s Pension Fund sold almost 25M shares, for example https://www.bloomberg.com/news/articles/2021-01-29/reddit-fe...)
Without knowing when they entered their position. It was hovering around $4 for a long time last year.
Even if they bought in at $5, selling at $20 is absolutely a win. Yes, they could have gambled and HODL'd, but there's no reason to gamble after seeing a 4x increase on a stock very few people expected would ever break $10.
Pensions dont make short term investments, they already had GME shares since a long time ago. They do sell when extraordinary circumstances happen and buy other stocks to hold long term again.
