空头股票补仓与平仓概述

简介

持有空头股票头寸的客户会面临头寸通常会在IB无事先通知的情况下被补仓、平仓的风险。这是卖空交易所固有的风险,通常不受客户控制。这还受到监管法规的限制,这些法规指定了经纪商必须遵守的时间安排。

虽然效果相同,但补仓是指第三方采取的行动,而平仓则由IB操作。这些行动通常由以下三种情况导致:

1. 卖空交易结算时需要交割的股票无法借到;
2. 结算时成功借到并交割的股票随后被召回;或
3. 无法完成清算所交割。

下方列出了三种情况的概述及相关注意事项。


补仓/平仓概述

1. 卖空交易结算 – 卖空股票时,经纪商必须安排结算时需借用的股票,如果是美国证券,结算日是指成交日之后的第二个工作日(T+2)。执行卖空交易前,经纪商必须通过验证股票当前的可用性来确定在需要时会有股票可用于借用。请注意,如果没有预先安排,便无法确保成交当天可用于借用的股票在两天后仍然可用,而如果没有可用股票,卖空将面临强制平仓。确定平仓的处理时间安排如下:

T+2(美国东部时间全天)
14:30 - 如果IB到目前为止仍未能借入股票满足结算要求,且预料到其极有可能无法借到股票,IB将会在尽最大努力的基础上发送消息通知客户潜在的平仓风险。客户需要在当日延长交易时段结束前自己平仓空头头寸以避免被强制平仓。如果在任何时候能够借到股票,IB也会通知客户。

15:15 – 如果客户未平仓空头头寸而IB也未能借到股票,IB将在尽最大努力的基础上向客户发送消息。客户仍需要在当日延长交易时段结束前平仓空头头寸以避免被强制平仓。

16:50 – 如果未能借到股票满足结算要求,IB将在尽最大努力的基础上发送消息通知客户如果在T+2工作日收盘前仍未能借到股票,其会在T+3工作日09:00之前进行最后尝试。

T+3
09:00 – 如果IB在09:00之前未能借到股票,平仓将在东部时间09:30开盘时开始。平仓将以参考价格反映在TWS交易窗口。

09:30 – IB采用交易量加权平均价定单(VWAP)发起平仓,时间覆盖整个交易日。TWS交易窗口中反映的参考价格将在平仓完成后更新为实际价格。


2. 召回– 一旦卖空交易完成结算(即已借入股票向买方进行了交割),股票的出借人便有权随时要求返还股票。如果发生召回,IB会尝试用从另一个出借人处借到的股票来替换先前借到的股票。如果无法借到股票,出借人有权发起正式召回,如果IB不归还被召回的股票,则会在正式召回发出后三个工作日内进行补仓。虽然发出正式召回为出借人提供了补仓的选择,但真正会导致补仓的比率很低(通常是因为IB能够从别处获得股票)。鉴于我们收到但不会采取针对性行动的正式召回通过太多,IB不会就这些召回通知向客户发出提前警告。

一旦交易对方向IB发送了补仓警告,其便能在对应交易日随时补进IB正在借入的股票。如果召回导致了补仓,出借人可执行补仓交易并通知IB交易的执行价格。IB会对交易对方的补仓价格进行审核看其是否符合当天的交易活动。
 
反过来,IB也会根据客户已结算的空头股票头寸将补仓分配给客户,而在确定负债时,未结算的交易是不纳入考虑的。一旦记入账户,客户便可在TWS交易窗口查看召回补仓交易,IB会在尽最大努力的基础上于东部时间约17:30之前向客户发出通知。


3. 无法交割 – 当经纪商在清算所有一项净空头结算义务但盘存没有可用股票或无法从另一经纪商处借入股票满足交割义务时,便会发生无法交割的情况。无法交割系因卖出交易导致,虽不限于卖空,但很可能是以保证金持有且可出借给其他客户之多头头寸的平仓交易所导致。

就美国股票而言,经纪商必须在下一个结算日常规交易时段开始之前处理无法交割的头寸。这可通过购买或借用股票来完成;但是,如果可用股票借入并不足以满足交割义务,IB将会以交易量加权平均价(VWAP)定单来平仓客户的空头头寸。

 

重要注意事项:

* 客户需注意,在被平仓的当天,客户须为被平仓之股票的净买入者,买入数量(其在公司所有账户总计)至少为其被平仓之股票的数量。在被平仓之交易日剩下的时间里,其将不能 (i) 卖空其被平仓的股票; (ii) 沽出其被平仓之股票的价内看涨期权;或 (iii) 行使其被平仓之股票的看跌期权(“交易限制”)。如果客户未能买入其被平仓之股票的规定股数(客户在公司所有账户总计)成为净买入者(例如,由于先前沽出的看涨期权被行权),公司将会在下一个交易日再进行一次平仓,平仓股数为在平仓当天客户距离成为该股票净买入者还需要再买入的股票数量,而客户也再次需要买入规定数额股票成为净买入者,并且在当日剩下的时间还会受到交易限制。


* 客户需注意,根据IB需要执行平仓和第三方可执行补仓的方式,可能会导致交易执行的价格和前一日收盘价之间出现巨大差距。对于流动性差的证券,这种差距会尤为明显。客户需随时注意这类风险,并对投资组合进行相应的管理。
 

 

Monitoring Stock Loan Availability

Overview:

Short Stock Availability (SLB) Tool
The SLB tool is available to IBKR account holders through Client Portal. Log in and select the Support section and then select Short Stock (SLB) Availability. This tool allows one to query information on a single stock as well as at a bulk level. Single stock searches can be performed by symbol/exchange, ISIN or CUSIP numbers. At the single security level, query results include the quantity available and number of lenders (note that a negative rebate rate infers a borrowing cost expressed as an annual percentage rate and, if positive, the interest rebate paid on cash proceeds securing the loan in excess of the minimum threshold). Information regarding the quantity of shares available to borrow throughout the day for the most current and past half hour increments is also made available.

 

In addition, borrowers interested in the trend of rates over the prior 10 day period can view the minimum, maximum and mean rates for each day.

This tool also allows one to upload a text file (with symbol/exchange or ISIN detail) and search for availability of multiple stocks in bulk within a single query. These bulk requests will then generate a .CSV file similar to the sample file output made available through the public FTP site.

India Intra-Day Shorting Risk Disclosure

Interactive Brokers currently offers the ability to short sell stocks before taking delivery on an intra-day basis. In accordance with IB’s intra-day shorting rules, traders are required to deliver shares sold or close short stock positions prior to the end of the trading session. 

Should traders establish a short stock position intra-day and still hold the position ten minutes prior to the end of the trading session at 15:20 IST, Interactive Brokers may, on a best efforts basis, close the position on your behalf. If the position is not closed by the end of the day and the shares are not delivered by the customer before settlement, the loss on account of auction will be borne by the customer. Please note that prices in the auction market are highly variable and typically not favorable compared to the normal market.

It is important to note, IB will not take into consideration any closing orders for short stock positions placed by the customer which may still be working. If your account holds a short position ten minutes prior to the end of the trading session and you have placed working orders to close those positions, there is the possibility your closing order will execute and that IB will act to close out your short position.  In this situation you will be responsible for both executions and will need to manage your long position accordingly.

A fee of INR 2,000 will be charged for this manual processing in addition to any external penalties in the case of short stock positions resulting in auction trades.  As such, we strongly urge customers to monitor their positions and take appropriate action themselves in order to avoid this.

Reg. SHO Short Sale Bid Test

Effective November 10, 2010, an amendment to SEC Reg. SHO goes into effect which will place certain restrictions on short selling when a given stock is experiencing significant downward price pressure.  This amendment, referred to as the alternative uptick rule (Rule 201) introduces a circuit breaker which takes effect wherever the primary listing market declares that a stock has declined 10% or more from the prior day’s closing price. 

Once the circuit breaker has been triggered, a Price Restriction is imposed which prohibits the display or execution of a short sale transaction if the order price is at or below the current national best bid. As a result, short sellers will not be allowed to act as liquidity takers when the Price Restriction applies and can only participate as liquidity providers adding depth to the market.  Individuals owning and attempting to sell a security subject to a Price Restriction (i.e., long sellers) are afforded a priority over short sellers in that while they are similarly prohibited from displaying or executing a sale transaction at a price below the current national best bid, they may display or execute orders at the bid.  Accordingly, long sellers are allowed to act as liquidity takers. 

The Price Restriction will apply to all short sale orders in that security for the remainder of the day as well as the following trading day.  Note that while the Price Restriction can only be triggered during regular trading hours, the restriction itself extends beyond regular trading hours on both the first and second days. In addition, there is no limit on the number of consecutive days in which a primary listing market can trigger a Price Restriction. If a stock currently subject to a Price Restriction again declines 10% or more from the prior day’s closing price, the restriction will be re-triggered for the remainder of that day as well as the following trading day.  

Rule 201 applies to all National Market System (NMS) securities; that is, stocks listed on a U.S. stock exchange whether traded on an exchange or in the over-the-counter market.  It does not apply to stocks which are traded only on the OTCBB and/or PINK nor stocks of U.S. companies which are executed on a non-U.S. exchange.

 

Example: Assume hypothetical stock XYZ closed yesterday at $10.00 and today reports a trade at $8.99 (down 10.1%) with a NBBO of $8.98 x $9.00. As the stock has declined by greater than 10%, the primary listing market would trigger the circuit breaker, effectively prohibiting the display or execution of a short sale order at $8.98 or less even if the order was a market order or had a limit price below $8.98.  The short sale order may only be displayed or executed at $8.99 or higher (assuming the stock trades in one penny increments). A long sale order could only be displayed or executed at $8.98 or higher. This Price Restriction would remain in effect for the remainder of today and tomorrow (assuming no subsequent price declines of 10% or more).

Why does the "price" on hard to borrow stocks not agree to the closing price of the stock?

In determining the cash deposit required to collateralize a stock borrow position, the general industry convention is for the lender to require a deposit equal to 102% of the prior business day's** settlement price, rounded up to the nearest whole dollar and then multiplied by the number of shares borrowed.  As borrow rates are determined based upon the value of the loan collateral, this convention impacts the cost of maintaining the short position, with the impact being most significant in the case of low-priced and hard-to-borrow shares. Note, for shares not denominated in USD the calculation will differ. Find below a table summarizing the calculations per currency:

Currency Calculation Method
USD 102%; rounded up to the nearest dollar
CAD 102%; rounded up to the nearest dollar
EUR 105%; rounded up to the nearest cent
CHF 105%; rounded up to the nearest rappen
GBP 105%; rounded up to the nearest pence
HKD 105%; rounded up to the nearest cent

For US Treasuries and corporate bonds, the collateral amount on which the borrow fee is charged will include the accrued interest.

Account holders may view this adjusted price for a given transaction in the "Borrow Fee Details" section of the daily account statement.  Two examples of this collateral calculation and its impact upon borrow fees are provided below.

 

Example 1

Sell short 100,000 shares of ABC at a price of $1.50

Short sale proceeds received = $150,000.00

Assume the price of ABC falls to $0.25 and the stock has a borrow fee rate of 50%

 

Short stock collateral value calculation

Price = 0.25 x 102% = 0.255; round up to $1.00

Value = 100,000 shares x $1.00 = $100,000.00

Borrow fee = $100,000 x 50% / 360 days in year = $138.89 per day

Assuming the account holder's cash balance does not include proceeds from any other short sale transaction then this borrow fee will not be offset by any credit interest on the short sale proceeds as the balance does not exceed the minimum $100,000 Tier 1 threshold necessary to accrue interest.

 

Example 2 (EUR denominated stock)

Sell short 100,000 shares of ABC at a price of EUR 1.50

Assume a prior business day's close price of EUR 1.55 and a borrow fee rate of 50%

Short stock collateral value calculation

Price = EUR 1.55 x 105% = 1.6275; round up to EUR 1.63

Value = 100,000 shares x 1.63 = $163,000.00

Borrow fee = EUR 163,000 x 50% / 360 days in year = EUR 226.38 per day

 

** Please note, Saturdays and Sundays are treated as a Friday and will use Thursday's settlement price to calculate the required deposit.

When I short a stock, when will the hard to borrow interest begin accruing?

Short positions will have a borrow interest/fee associated with them.

Borrow interest will begin being charged on a short position from short settlement date to buy-to-cover settlement date.

For example, you sell XYZ on Monday, and you close the position on Tuesday. Borrow interest would start to be charged upon Wednesday's settlement date (T+2). Interest would cease to be charged on Thursday, the settlement date (T+2) of the buy-to-cover order.

 

Overview of Short Stock Buy-Ins & Close-Outs

Introduction

Clients holding short stock positions (including short positions resulting from option assignments or exercises) are at risk of having these positions bought-in and closed out by us, oftentimes with little or no advance notice. This isrisk which is inherent in short selling and generally outside the control of the client. “Buy-ins” are conducted in accordance with regulatory rules that dictate how and when buy-ins are conducted.

While similar in their effect, the term “buy-in” refers to an action taken by a third party and a “close-out” refers to an action taken by us. These actions typically result from one of three events:

1.     The shares required to be delivered when a short sale settles cannot be borrowed;

2.     The shares which were borrowed and delivered at settlement are later recalled; or

3.     A fail to deliver with the clearinghouse occurs.

An overview of each of these three events and their considerations is provided below.

1. Short Sale Statement

When stock is sold short, the broker must arrange for the shares to be borrowed for delivery by the settlement date, which in the case of U.S. securities is the second business day following the date of the trade (T+2). Prior to executing the short sale, the broker must have reasonable grounds to believe that the security can be borrowed so that it can be delivered on the date delivery is due. This is accomplished by verifying the current availability of the shares for borrowing. Note that there is no assurance that shares available to borrow on the date of trade will remain available to borrow 2 days later for delivery at settlement, and the short sale may be subject to forced close-out if the shares can no longer be borrowed for delivery. If the client “pre-borrows” shares to deliver at settlement (i.e., actually borrows shares before selling short) the client will not be subject to a close-out as long as the borrowed shares remain available. The processing timeline for determination of a close-out is as follows:

T+2

If we are unable to borrow shares to deliver on settlement date (T+2), we have until market open of the following day, T+3, to cover the delivery obligation and prevent close-outs.

T+3 (all times in ET)

09:20

If we were unable to borrow shares to meet settlement, a communication will be sent, on a best efforts basis, notifying the client that a close-out will occur.

09:30

We initiate the close-out by placing an order prior to the open of regular trading hours. The close-out quantity will be reflected within the TWS Trades window. Since the final close-out price may not be known until the end of the day, the previous trading day’s closing price is used as a placeholder price on TWS. The placeholder price will be updated with the actual execution price upon completion of the close-out order.

It is possible that under certain circumstances, due to limited liquidity in the market, that the close-out order may not be executed or may be only partially executed. In that case, the initial close-out quantity will be corrected down to the executed quantity. The remaining quantity will remain subject to close-out at the start of regular trading hours the following business day.

2. Loan Recall

Once a short sale has settled (i.e., stock has been borrowed and used to deliver the shares sold short to the buyer), the lender of the shares reserves the right to request their return at any time. Should a recall occur, we will attempt to replace the recalled shares with those from another lender. If the recalled shares cannot be replaced within two days of the recall notice, the lender can issue a formal Buy-In Warning which allows for a buy-in to take place that day. While the issuance of this formal warning provides the lender the option to buy-in, the proportion of recall notices that actually result in a buy-in are low (typically due to our ability to source shares elsewhere). Given the volume of formal recalls which we receive but are not later acted upon by the lender, we do not provide clients with advance warning of these recall notices.

Once a counterparty issues a Buy-In Warning to us, the counterparty may buy-in the shares we are borrowing at any time for that trade date. In the event the recall results in a buy-in, the lender executes the buy-in transaction and notifies us of the execution price. We conduct vetting of counterparty buy-in prices for appropriateness with the day's trading activity.

In turn, we allocate the buy-in to clients based upon their settled short stock position. Unsettled trades are not considered when determining liability. Recall buy-ins are viewable within the TWS Trades window once they are posted to the account by approximately 17:30 EST.

3. Fail to Deliver

A fail to deliver occurs when a broker has a net short settlement obligation with the clearinghouse and does not have the shares available within its own inventory or cannot borrow them from another broker in order to meet the delivery obligation. A fail to deliver can result from a long or short sale.

In the case of US stocks, brokers are obligated to close the fail position by no later than the start of regular trading hours on the day following the settlement day. This can be accomplished by delivering purchased or borrowed shares. If available stock borrow transactions prove insufficient to satisfy the delivery obligation, we will close-out clients holding short positions by placing an order prior to the open of regular trading hours. It is possible that under certain circumstances, due to limited liquidity in the market, that the close-out order may not be executed or may be only partially executed. In that case, the initial close-out quantity will be corrected down to the executed quantity. The remaining quantity will remain subject to close-out at the start of regular trading hours the following business day.

Important Notes

Clients should note that on any day on which they have been closed out, they are required to end the day as a net purchaser—in aggregate across all of their accounts with the Firm—of at least the number of shares they were closed out on (in the security they were closed out on). As a result, for the remainder of the trading day on which a client was closed out, that client will not be permitted to (i) sell short the stock they were closed out in, (ii) write in-the-money call options on the stock they were closed out in, or (iii) exercise put options on the stock they were closed out in (the "Trading Restrictions"). If a client nevertheless does not end the day as a net purchaser of the required number of shares for the stock they have been closed out in (for example, as the result of being assigned on call options previously written)—in aggregate across all of the client's accounts with the Firm—the Firm will perform another close-out in the account on the next trading day for the number of shares that, when added to the client's aggregate net trading activity in such stock on the close-out date, would have been required to make the client a net purchaser of the required number of shares of such stock that day, and the client will again be required to remain a net purchaser across all of their accounts of that many shares and again subject to the Trading Restrictions for the remainder of that day.

 

Clients should be aware that based on the manner in which we are required to execute a close-out and a third party is allowed to execute a buy-in, significant differences between the price at which the transaction was executed and the prior day's close may result. These differences may be especially pronounced in the case of illiquid securities. Clients should be aware of these risks and manage their portfolio accordingly.
