I don't see JPM and Fidelity on the list. Where did you get that part from?
As I said, that is the list of companies who have "completely" liquidated their holdings. JPM liquidated 41% (not 100%).
JPM's top holdings
They decreased their position in MS by 10%. MS was lead underwriter for SNAP. They also decreased their positions in BLK Blackrock, TROW T Rowe Price, BAC Bank of America, ... who have major positions in SNAP. Banks alone have lost more than $1 billion.

The amount of external manipulation should be telling enough. The stock dropped Q1 by ~25% and they did not enforce a short sale restriction. But, come Q2 when it misses its ER like we all knew it would they enforced a SSR.
According to SEC Rule 201 they enforce a SSR if an equity drops more than 10% from previous close during RTH as def. by NMS 600b64. From $13.50 to $11.80. $BAC, $BARC whip out their price targets of $17



and Drexel Hamiton pounds the table with its $30 target

Never have I seen so much done to save a POS company. Their desperation has revealed their hand.
JPM had 11,202,277 shares valued at time of reporting to SEC to be $252,388,000.
The avg price $22.53
Sells 4,603,386 shares + a few more
JPM has 6,598,891 shares valued at time of new 13F-HR to be $117,262,000.
avg price = $17.77
(22.53-17.77)*4,603,386 = $21,912,117 realized loss
(22.53-11.80)*6,598,891 = $70,806,100 unrealized loss
that's almost a hundred million on only one equity in their portfolio of 2,500+
FMR LLC
(22.03-17.34)*18,244,094 = $85,564,800 realized loss
(22.03-11.80)*15,206,191 = $155,559,333 unrealized loss
a quarter billion dollar loss on stock they are not near as big as JPM.
I have not even begun to calculate this for people like BARC and landsowne UK, companies in the UK. Not to mention that JPM, GS, BAC, BARC have massive call positions.
