Fast Money

India's retail day traders have collectively lost billions of rupees betting on short-term stock and index options trades. Reports point to heavy losses among small investors drawn in by the country's booming derivatives market, the world's largest by volume.

Private foreign buying of longer-term US Treasuries has fallen to roughly $263 billion over the last 12 months, nearly half the $506 billion purchased in the prior 12-month period, according to figures being circulated by market commentators. Observers say the drop signals fading overseas appetite for US long-term debt, though they note foreign money is not leaving the US entirely but shifting into other assets, raising questions about how easily America can fund its deficits.
