noun
sacrifice goods; liquidation of shares; things thrown out
Covers three distinct usages: (1) goods sold at a loss or as loss leaders, (2) shares sold off cheaply, and (3) discarded items. Context determines which meaning applies.
あの店は投げ物の特売で客を集めている。
That store attracts customers with a special sale on loss-leader items.
市場で投げ物の株が大量に出回った。
A large number of shares were dumped on the market at bargain prices.
When moving, I gathered up all the things I was throwing out and disposed of them.
投げ売り is a more common term for selling at a loss or dumping goods/shares, while 投げ物 can refer to the items themselves or the act of throwing away.
捨て物 specifically means discarded items or things to be thrown away, whereas 投げ物 has broader meanings including sacrifice goods and liquidation.
Compound of 投げ (nagé, 'throwing') + 物 (mono, 'thing'). The exact historical derivation is uncertain; the term is used in commercial and disposal contexts.
