Has anyone peer-review researched investors buying another, but similarly spelled, ticker? GLDD - Believing Robinhood users are dumb is profitable... : wallstreetbets

Academics need to research the correlation between performing tickers and their closely related (only in name) cousins.


Have any academics done so?

Has any forensic linguist investigated the morphological traits behind such &quot;false friends&quot;?


E.g. in February 2020, many investors misconstrued ZOOM for their desired ZM (Zoom Video Communications). Similarly, I wonder if some investors misconstrued GLDD (Great Lakes Dredge and Dock Company) for their desired GLD, or KDKN (Kodiak Energy) for their desired KODK (Eastman Kodak Company).
Yes, this has been done. Balashov and Nikiforov (2019) studied firms with similar tickers and found 25% had comovement in turnover and estimated 5% of turnover was due to investor confusion
