Perma-bulls get destroyed, fakestream media always tries to make the fools hold their positions ("its just a minor correction" they say) and tries to deter from the facts. The banking conglomerate needs liquidity and foolish buyers - so that they can exit their positions safely with maximum returns.
Don't be a sheep. The charts reveal everything, they always do.
