I must say that I am absolutely flabbergasted of what hedge funds and other investors can do in the dark to manipulate stock price, scaring retail investors into selling, and try to cover their short positions.

More transparency AND bigger fines are an absolute must.

Please action on this and make sure this rule passes

Thank you,
