感謝，我明 box spread點運作，我係想知道多啲實際操作嘅caveat

我就係見開個option trade嘅 margin requirement 超級低，我借少少開1.4倍根本爆唔到，因為我拎套岀嚟嘅$9935去買股票 net liquidation value唔會變，要啲股票跌到去$25先可能爆？

但係個 monthly rebalancing 我擔心成本同spread都太高倒不如直接向broker借錢，但另一方面 box spread又有好難 margin call嘅優點（以我理解）

short box spread所佔嘅margin唔多，但係你買貨都會佔margin。
以VOO為例，maintenance margin只係9%。

例如你本身有$10000現金，然後買$10000 VOO，maintenance margin就係$900。再用short box spread套$10000現金出嚟，maintenance margin就係$925。

然後再用$10000現金買VOO，maintenance margin就係$1825。
如果VOO跌一半，你NLV就歸零，maintenance margin就係$925 [= ($10000/2+$10000/2)*9% + $25]
咁就已經爆咗倉，一定要補倉或者賣貨。

更加慘嘅情況係券商可能會喺市況波動嗰陣冇啦啦提高margin requirement，例如由9%加到15%，咁又會更加容易爆倉。

唔該巴打，明了，無真係用過 margin account唔太熟，返去認真計吓數先。都係當maintenance margin 30%安全啲

咁計同去 broker借錢爆倉機會差唔多？我有$10000 cash, 借broker$10000去買VOO, maintenance margin係$1800，跌一半嘅話就NLV係0，但maintenance margin係$900咁樣？

走咗？

兩者差唔多都合乎efficient market hypothesis嘅。
唔會有兩樣嘢效果相同，但其中一樣有明顯優勢，同時又冇咩缺點。

仲有唔同方法可以套現金嘅，例如用short DITM put取代SPY, short inverse LETF，不過都各有風險同缺點。

short DITM put我以前都玩過，例如SPY$600，我就揀$800 short put。
結果一兩日就畀人early exercise，最後都係冇咩著數。

唔該巴打，咁睇嚟box trade都係要當普通Margin咁風險管理

題外話，有冇人試過做 constant volatility / downside volatility, 實際操作係點搞

你做 short put 嗰陣最緊要係睇 extrinsic value, 依個係你嘅護城河
你做 short ditm put, extrinsic value 一定好接近0, 所以人地會 exercise
若果你做 short atm put, 唔係就到期/跌到變 ditm 人地都唔會 exercise

Palantir Technologies (PLTR) leads the list of a half dozen companies that could be added to the $26 trillion Nasdaq 100 index NDX at its annual reconstitution due to be announced on Dec. 13.

Other candidates for inclusion at the reconstitution, in order of market value, are MicroStrategy (MSTR), Equinix, CME Group, Interactive Brokers, and Coinbase Global, according to Dow Jones Market Data.

入完就跌返落去搵d passive fund笨

之前已經講過呢個問題
佢同mstr 都係溢價過高
依家入納指=幫手出貨+整跌nq

是

入返咪開心返

以前工作太忙年年都係rollover定期，到家陣終於dick起心肝做passive investor先
打算每次留50000左右比我做半年比我in case有咩事都有liquid capital
家陣all in SPY/VOO，等自己beta上進可攻退可守
然後買少少TLT等自己叫股債配合
之後再揀多個市場 同 fund嘅類型/sector比自己玩
唔該晒眾多ETF post嘅巴打排解疑難
唔介意嘅話可以一直同大家吹水

ＡＴＨ 點敢入，入都係入極少

已AＬＬ ＩＮ？

份糧出咗已經射咗30%去VOO
等下個月定期放返出嚟就all in
大家好似建議我呢個傻散玩VOO多過SPY話management fee平

啲人走去玩韓國3X ETF

屌你老母tmf

第一個月月供？加油
VOO係好過SPY 除非要玩option

係

又爆升

賣唔賣d tqqq好？

TQQQ破頂既話點慶祝好

有冇巴打記得11月15日發生咩事？
納指、標普、TMF喺嗰日之後特別精神咁
