Which is true for some stocks, stocks which aren't held by institutions, but this is Intel. Being Intel, they have a large amount of shares held by institutions (I'll just quote the Yahoo Finance table for brevity). Since they are looking for shareholders who lost money during the period, not just shareholders who bought during the period, it makes them all fair game. Vanguard and Blackrock alone total well over half a billion shares, so even if the recovery to shareholders were to be 20% of lost value (about $2 a share as it dropped $10 a share during the class period), it's a significant amount of fee for the lawyers, so it won't be dropped, and the lead plaintiff will likely be a state or institution rather than one specific person.
