Perhaps, even probable, the genius of Elon Musk is being observed at work.
He has destroyed Twitter at a near $0 cost. Twitter stock is becoming worthless because the false facade is transparently destroyed.
Twitter is actually a business that must provide the stock holders, mostly institutional companies, with a return. There are no dividends
There is no more possibility of growth. Shorting is the profitable way but when the fire sale begins, that won’t work for most. For prudent businesses, selling out is the only rational action.
Umm, 0 cost? Musk owns like 9 billion dollars worth and as it falls so does his share value.
