I recently came across Tiziana Life Sciences, a small UK biotech company with the US ticker TLSA — which is a fat finger error away from Tesla ($TSLA).

Tesla's share price has increased by ~250% year-to-date. In the same period, Tiziana Life Science has increased by ~220%. Other biotech stocks are doing pretty well, but the small-cap index $BTEC has climbed only ~22% in 2020. Perhaps I'm missing something about Tiziana's business, but it looks suspiciously like their valuation is typo-driven.
