MicroStrategy’s Nasdaq Entry Kicks Off New Era of Momentum Risk

MicroStrategy Inc.’s entry into the Nasdaq 100 opens up the largest corporate holder of Bitcoin to a new — and untapped – investor: the index-tracking juggernauts.

Yet Wall Street pros warn the oncoming march of these price-insensitive investors threatens a new source of vulnerability in a stock that has soared more than 500% this year on booming demand from retail investors, as well as hedge funds capitalizing on its volatility.

MicroStrategy’s Nasdaq admittance, scheduled for after the close of trading Friday, looks poised to prompt passive investors to buy roughly $2 billion of shares, a Bloomberg Intelligence estimate shows. The incorporation was cheered by crypto bulls as further evidence of mainstream adoption.

At the same time, price-agnostic indexing flows can work against a stock — exacerbating declines once momentum turns. For evidence, look no further than Super Micro Computer Inc., which will be dropped out of the tech-heavy benchmark at the same rebalancing event, after winning a prestigious spot in July amid the craze over artificial intelligence. The stock fell 8.3% Monday despite broad market buoyancy.

While Super Micro remains an extreme case — with concerns over corporate governance fueling a big stock rout — the index round trip serves as a reminder of the risks involved in passive investing.

Research earlier this year by Dimensional Fund Advisors, an active manager, found that this so-called index effect remains a feature of the investment landscape, with benchmark-tracking vehicles often systematically buying when the price is high and selling during the lows.
