买国能不到 5 年损失 50% 的本金， 还有人忽悠你买国债

[苍井吱]

那5年后能买到打5折的(假设)10年国债，持有5年直接翻倍？

你买的是thirdparty把，auction的没有手续费的。

如果不在券商買，如果買10年的，一年後怎麼賣呢？

[magagop]

Fidelity可以买。选择“auction” 。明天拍卖20年期

TreasuryDirect不能賣，Fidelity賣bond要不要手續費？難道也是免費的？我記得IB買免費，賣要$10手續費。

You cannot sell a Treasury marketable security directly from your TreasuryDirect account. To sell a Treasury marketable security that is in your TreasuryDirect account, you must transfer the security to a broker/dealer account. The broker/dealer can sell the security for you.

Minimum mark-up or mark-down of $19.95 applies if traded with a Fidelity representative. For U.S. Treasury purchases traded with a Fidelity representative, a flat charge of $19.95 per trade applies. A $250 maximum applies to all trades, reduced to a $50 maximum for bonds maturing in one year or less. Rates are for U.S. dollar–denominated bonds; additional fees and minimums apply for non-dollar bond trades. Other conditions may apply; see Fidelity.com/commissions for details. Please note that mark-ups and mark-downs may affect the total cost of the transaction and the total, or "effective," yield of your investment. The offering broker, which may be our affiliate, National Financial Services LLC, may separately mark-up or mark-down the price of the security and may realize a trading profit or loss on the transaction.
