There’s been a lot of talk about “Robinhooders” piling into risky stocks over the past few months, but I’ve yet to see much data that could explain the influence that this relatively small brokerage could have on price discovery. Using the website robintrack.net, which publishes a history of the total numbers of “owners” of each individual stock in the Robinhood universe, I decided to aggregate the data to see for myself.

With a cursory glance, you’ll see a LOT of charts that look like this:

Yes, that’s American Airlines (NASDAQ:AAL) ownership increasing 41x since the beginning of the pandemic. Looks like we found out who Warren Buffett sold his airline stock to!

This is the part where you tell me “wait a minute… Berkshire (BRK.B) owned nearly 42 Million shares of AAL stock or nearly 8% of outstanding shares. Surely, Robinhooders haven’t purchased that amount of stock.” Well, you’re probably right; but don’t be so sure.

I decided to repeat this analysis for all of the stocks that have traded for the entire calendar year 2020 and were held in at least 1,000 portfolios as of 3/1 to identify stocks that rapidly increased in ownership between 3/1 (pre-pandemic) and 8/1 (time of writing).

Here are the top 10:

Ticker

Implied Ownership ($100 Avg. Position) Growth 3/1-8/1 2020

NCLH

0.9% 186x
HTZ 6.6% 119
UCO 1.0% 101x
UAL 0.3% 66x
SAVE 1.5% 64x
TOPS 20.7% 64x
GNUS 5.5% 59x
RCL 0.2% 57x
PLAY 2.6% 45x
AAL 1.2% 41x

These tickers represent: 1 bankrupt car rental company (HTZ), 1 leveraged oil ETF (UCO), 2 cruise lines (NCLH & RCL), 2 penny stocks (TOPS & GNUS), 3 airlines (UAL, SAVE & AAL) and to top it all off Dave & Busters (PLAY).

So now, what do we do with this information? I’m not an expert bankruptcy law, so I have no way to value HTZ. I don’t want to deal with the randomness inherent in penny stocks, so goodbye TOPS & GNUS. The whole world has eyes on oil, airlines and cruises; Robinhood is but a very small pawn in that game.

This leaves me with PLAY. If the average Robinhooder has a $100 position in PLAY, this probably doesn’t mean much. However, if you were willing to believe that the average position is closer to $500 or $1,000; then you’re left to face a stock where 15-25% of the interest is inexperienced, short-term money that could easily get spooked (or just get bored) and sell.

I don’t have any intention to use this information to trade, but if forced to put money in play, I’d buy $10 put options on PLAY for 11/20 with the intention of selling if the stock dipped below $10 or more than 50k accounts abandoned ownership by keeping up to date on this chart: https://robintrack.net/symbol/PLAY.

I may also do further analysis to identify Robinhood bubbles that expand and pop in days as opposed to months (e.g. NKLA). I might post about this in the future depending on the response to this post (comment if you’re interested)!

Caveats & Further Exploration:

If you want to explore more, you can do that here: robinhood_stocks.csv I only included stocks that grew 6x, which was a random cutoff, but it should be noted that the average increase in ownership across all stocks was ~3x which could be used as a proxy for account growth over the same timeframe, or may just indicate an increased number of positions per account. Regardless, a 6x increase during this timeframe is noteworthy.
