Drnick....I too, have Schwab & called about their "securities Lending program". The veteran, polite rep said that in his years there, he had never heard of such a dept but looking at his info, they indeed had one. Shows that it is unusual.
He put a broker on the phone from Securities lending & I was told that they were approached by other funds, hedge funds, etc (vague) from time to time asking for shares to short & were willing to pay for this use of the shares. He said he hadnt seen Wave come up in this regard & was unfamiliar with wave.
I asked if I could be correct in assuming naked shorters might be nervous & looking for actual shares....could this be a possible reason for such a letter, as Wave has a relatively small official short interest & unknown, maybe significant nakeds. To this, he said maybe, he supposed so, but didnt elaborate.
Interesting to see this twist in another trading venue & where this may be business as usual to many expert traders, I learned another phase of broker activity new to me. This is the way I heard it.
