Dangers of Owning Puts Without Owning the Stock

Some risks of owning put options while not owning the stock, are typically not well highlighted in mainstream options education materials. This is beyond the standard issues with options such as needing to be right in the direction (puts or calls), timing (before expiration), and magnitude (must cover the premium) of the stock movement.

If you own put options without owning the stock (regardless of whether you are hedging a long position on the stock through calls, or you are just a short seller betting the stock will fall), you can get into a bad situation in the following scenarios:


The stock is halted for some reason on the exchange (e.g. SEC investigation, exchange requesting for information, company wishes to announce major news such as auditor resignation), and the halt extends past the expiration date. When the stock gets halted, trading for the stock’s options will also be automatically halted. That means that you will not be able to sell your long put position. Note that no advance warning may be given for the trading halt, and the stock/options can be halted even in the middle of a trading session. The key question then is, are you able to exercise your put options during the halt.

There are many websites that say that yes you will be able to exercise your put options during the halt because a stock halt does not affect the rights and obligations of the options contract (read here, here, here). They basically advise that when you exercise your put options, you will end up with a normal short stock position, which you can then cover later when the stock resumes trading (even if the stock got delisted and trading is resumed at the OTCBB or Pink Sheets). Typically a stock opens about 2/3% down from the last price before the halt (read here) so that your put options serve their intended purpose.

The Options Clearing Corporation (OCC) / Options Industry Council also wrote in its FAQ (here) that even if a company goes bankrupt and its stock is halted, you can still exercise your options so long as the shares continue to exist.  The OCC also published info memos (see example here) that even though automatic exercise will be suspended (i.e. even if your option is in-the-money, it will not be automatically exercised as per normal), you can simply manually instruct the OCC to exercise the option (BTW, you can look up the latest info memos on your options by searching at

What’s The Problem?

All these sound great! So what’s the problem? The problem that I have not once seen mentioned in these sites is that your particular broker, cannot find the stock to deliver for the exercise of your put options, hence your broker does not allow you to exercise your puts, and your puts will expire worthless. This can happen with stocks that are already heavily shorted, or stocks with large put option open interest (relative to the float). And more often than not, if you are playing a situation where you are using puts, are you indeed in that particular situation.

From online forum postings where this scenario happened recently, TD Ameritrade allows you to put in a request for exercise before the expiration, which will be honoured when trading resumes (here , here, here), E*Trade allows for exercise only if you own the stock but not if it creates a short stock position (here), Interactive Brokers (here, here) is not allowing exercise if you don’t own the stock because there is no inventory (here, here, here, here). Note however that the situation can be dynamic from day-to-day, it is definitely possible that your broker managed to obtain shares for you to exercise your puts. Long story short, without owning the stock, you can be screwed.

From the point of view of the brokers, there are also issues they have to contend with

  1. If they can find the stock to perform the assignment, they are taking a risk with the opening price of the stock once trading resumes. If they perform the exercise, give you a short stock position, and the stock opens with the price doubled, there is a risk you don’t have the funds to close the position. In this case they may require 100% margin for the position (either 100% on top of the money you get from exercise, or based on the latest stock price before halting). This is similar to brokers raising the margin requirement for companies with binomial events that are coming up (e.g. margin requirement for MELA, MNKD raised before FDA drug approval decisions)
  2. If they take the stock from someone who has their holding already lent to a covered short (i.e. a put writer that is also short the stock), they cannot force a buy-in on that covered short because there is no market in the stock (trading halt). The lack of a market presents difficulties to brokers in reallocating already borrowed stock.

How Can It Play Out

How it can play out (the negative news scenario)

  1. The exchange determines whether the company is seriously working to resolve the issues. If deemed not sufficient, the exchange gives notice to the company of its failure to meet listing compliance with a notice of de-listing, and a chance to appeal.
  2. The company will decide whether or not to appeal, and may issue a press release on their decision.
  3. The exchange replies in about a week, and either announces a date for trade resumption or de-listing.
  4. If de-listed from the main exchange, the stock will resume trading on the OTC markets (e.g. OTCBB, Pink Sheets, Grey Sheets). Note that your broker may have certain restrictions on trading in OTCBB/Pink Sheets (some may only accept trades through the phone with high commission).

For the lucky ones that are able to find shares to hold a short position, from past similar situations, after the stock opens ~66% down when it resumes trading (this is the prime time to cover as people/institutions holding the stock are rushing for the exit at the bid), there could be a short squeeze where the stock can potentially go up 50%. After the squeeze, the stock will drop back down again. While that might cause you to think that its an opportunity to make a quick buck, don’t go there. If its already so hard to close an existing short position such that short sellers are buying into a squeeze, its even much harder to take two steps to initiate a fresh position then close it even higher. Of course if your company doesn’t recover from the halt and goes bankrupt (e.g. Chapter 11 or Chapter 7), your short stock position can be closed as though you buy-to-close at $0.

Can There Be a Massive Short Squeeze?

There is always some “debate” in the forums during that halt as to whether a massive short squeeze can be triggered after trading resumes.

What the Longs Say

  1. The short interest is way high relative to the float (can even exceed the float). The shorts will need to cover their positions, which will cause a short squeeze.
  2. SEC enforcement of Reg SHO will force the brokers to force cover short stock positions.
  3. Massive short squeeze has occurred before in other stocks. Corus Bankshares jumped from $1 to $8 on a massive short squeeze  before being closed by the FDIC in 2009.
  4. Shorts have to pay a high interest cost to maintain the short, such as a hard-to-borrow fee for stocks that are tough to find (this is dependent on each brokerage). Such interest can range from 7.5% p.a. to 200% p.a. on the dollar amount of shares shorted. China North East Petroleum (NEP) was halted from May 26, 2010 to Sep 08, 2010 (inclusive), i.e. 106 days, or 3 months 14 days. The interest to be paid could kill the shorts during the halt.

What the Shorts Say

  1. Put writers that get stock assigned to them may not have enough equity in their margin account, especially when such risky stock requires 100% margin. This will trigger margin calls and pressurise them to dump.
  2. Exercise of put options creates a short stock position (put holder) and an equal long stock position (put writer) at the same time. The person with the short stock position can essentially borrow from the equal long stock position, so the “short situation” has not worsened at all.
  3. Most brokers will not ask clients to immediately cover their short stock position if they meet the margin requirements.
  4. Institutions owning the stock will be forced to dump the stock to adhere to their internal rules.
  5. All longs will rush for the exit, no one will be so naive to trust that all longs will cooperate with high limit orders. If there is any spike in the price, longs will rush to sell, effectively ensuring that the price stays down.
  6. The longs’ trust in the company is already shattered, it will take good news and the stock price to rise for the shorts to lose.
  7. The same situation happened with RINO and people were selling at the bid when the stock resumed trading on the pink sheets.

Case Study (RINO)

RINO was a China-based maker of water treatment / pollution control equipment.

Institutional Holders (below RINO blew up): UBS, Bank of America, Deutsche Bank, Barclays and Credit Suisse. Eric Jackson ( reported that Deutsche Bank increased its RINO position by 38% in 3Q 2010.

Dec 23, 2009 Rodman & Renshaw reiterates “Outperform” rating with price target of $40. Rodman & Renshaw basically kept reiterating their $40 price target under they downgraded it on Nov 17, 2010.
Jul 11-13, 2010 RINO presented at Global Hunter Securities 2010 China Conference at St. Regis Hotel, San Francisco.
Sep 27, 2010 Global Hunter initiates coverage with a “Buy” and price target of $20.

RINO stock was trading around $13-$15 in Sep 2010.

Oct 29, 2010 Downgraded from “Buy” to “Hold” by Cannacord, which highlighted that increasing competition may undermine profitability. Price target lowered from $25 to $18.

RINO stock was trading around $18-$20 in end-Oct 2010.

Nov 02, 2010 Global Hunter cuts rating to “Neutral” on increased competition from flue gas desulfurization (FGD) market and steel mill power shortages in China.
Nov 10, 2010 Muddy Waters initiates coverage with a Strong Sell and a $2.45 price  target. Key points made quoted below: 

  • RINO’s FGD sales (60% to 75% of revenue) are much lower than it claims. We found that many of its customer relationships do not exist.
  • Chinese regulatory filings show that RINO’s consolidated 2009 revenue was only $11 million, or 94.2% lower than it reported in the US. We show that the Chinese numbers are credible.
  • RINO’s accounting has serious flaws that are clear signs of cooked books.
  • RINO’s management is draining cash from the company for its own business and personal uses. The management is in flagrant breach of its VIE agreements, which require it to pay income to RINO (as opposed to taking it).
  • RINO’s balance sheet has an astonishingly small amount of tangible assets for a manufacturer. Rather, it is filled with low quality “paper” assets that balance out the inflated earnings, and likely hide leakage.
  • RINO is not the industry leader it claims to be in the steel sinter FGD system market. Rather, it is an obscure company in a crowded field, and is best known for its failed projects. Its reported margins are two to three times what they really are. Its technology is sub-par.
  • We are not sanguine about management “borrowing” $3.2 million to purchase a luxury home in Orange County, CA the day that RINO closed its $100.0 million financing.

RINO stock plunged from $15.52 (Nov 9) to $11.10 (Nov 11).

Nov 11, 2010 RINO commented on Muddy Waters report with “RINO takes its responsibilities to investors very seriously and has launched an internal review of Muddy Waters’ allegations. RINO looks forward to providing investors with a timely and detailed response to the allegations upon completion of its internal review”.

RINO stock plunged from $11.10 (Nov 11) to $7.55 (Nov 15) over a weekend.

Nov 15, 2010 RINO released Q3 results after U.S. market closed.

Cannacord cuts rating from “Hold” to “Sell”, highlighting that the company is not putting up a defense on the fraud allegations, and the real business could indeed be significantly smaller than what the reported financial statements suggest.

Nov 16, 2010 RINO postponed Q3 conference call.
Nov 17, 2010 @ 11:54:11 a.m EST RINO was halted for “news pending” at a last sale price of $6.07.
Nov 17, 2010 Global Hunter suspended coverage due to lack of company response to fraud allegations.

Rodman & Renshaw downgraded it to “Under Review”.

Nov 17, 2010 RINO filed a 8-K stating that Frazer Frost LLP (their auditor) delivered a letter on Nov 17, 2010 to RINO’s Board of Directors with the following points:

  • RINO’s CEO, had told Frost that 2 of the 6 customers cast doubt upon by research firm Muddy Waters were, in fact, never actually engaged in a contract with RINO.
  • The CEO highlighted that there might be problems with 20% to 40% of RINO’s other customers.
  • Frost recommended that the company’s management throw out its audits of RINO for 2008 and 2009, and the quarterly financial statements through September 30, 2010, and await revised financial statements.
Nov 19, 2010 NASDAQ announced that the trading halt status was changed to “additional information requested” from the company.
Nov 29, 2010 Post on Yahoo! Message board highlighted that there will be a report out that day on RINO delisting from the NASDAQ.
Dec 02, 2010 RINO filed an 8-K and announced that it has received a letter from NASDAQ on Nov 29, 2010 stating that based upon its review of the Company and pursuant to NASDAQ Listing Rules 5101, 5250(a)(1) and 5250(c)(1), the staff of NASDAQ believes that the continued listing of the Company’s securities on NASDAQ is no longer warranted. NASDAQ staff’s determination was based on the following:

  • The Company’s announcement that its previously filed financial reports for fiscal 2008, 2009 and year-to-date 2010 could no longer be relied upon;
  • The Company’s admission that it had not entered into certain previously disclosed contracts; and
  • The Company’s failure to respond to the NASDAQ staff’s request for additional information regarding allegations raised by the Muddy Waters, LLC report.

The NASDAQ Letter stated that the statement by the Company’s independent auditors that their audit reports for 2008 and 2009 can no longer be relied upon constitutes a violation by the Company of NASDAQ Listing Rule 5250(c)(1). The letter also states that the Company’s failure to respond to a letter from the NASDAQ staff dated November 17, 2010 constitutes a violation of NASDAQ Listing Rule 5250(a).

The NASDAQ Letter further notified the Company that unless the Company requests an appeal of the NASDAQ staff’s determination, trading of the Company’s common stock will be suspended at the opening of business on December 8, 2010 and a Form 25-NSE will be filed by NASDAQ with the SEC, which will remove the Company’s securities from listing and registration on NASDAQ.

RINO stated that “The Company does not intend to appeal the NASDAQ staff’s determination to delist the Company’s common stock. Pending the delisting of the Company’s common stock, which is expected to occur on December 8, 2010, the suspension of trading in the Company’s common stock, which commenced on November 17, 2010, remains in effect.

The Company currently intends to re-apply for a listing of its common stock on NASDAQ at an appropriate time after the completion of an independent investigation to be conducted by the Audit Committee.”

RINO also disclosed that it has been notified by the Staff of the SEC that the SEC was conducting a formal investigation relating to the Company’s financial reporting and compliance with the Foreign Corrupt Practices Act for the period January 1, 2008 through the present.

Dec 08, 2010 RINO.PK opened on the pink sheets for trading.

There were 2 dead cat bounces from Dec 08, 2010 to Jan 08, 2011 before hitting a low of $2.00 on Jan 20, 2011 (~1.5 months after it resumed trading)

This was followed by another bounce before hitting a low of $1.55 on Mar 07, 2011 (3 months after it resumed trading).


What’s the Solution?

  1. Don’t play such a situation in the first place.
  2. If you are using puts for protection, own the stock (duh!), if you are worried about taking up too much of your capital, reduce your position, don’t risk it.
  3. Buy put options with expiration some months (2-3 months) out if you expect a significant event around a certain time so that the stock would have resumed trading before your options expire.
  4. Buy put options on other stocks that will drop significantly (but does not have an impending event that could get it halted) if this stock got halted. Note that the prior correlation does not matter. It is a case where when bad things happen, suddenly correlation increases towards 1. E.g. if a Chinese RTO stock got hammered, many other Chinese RTO stocks will get hammered as well.


This scenario is a more typical scenario that people would usually think about. That is, the stock does not get halted, but it stays at a level above your strike price until option expiration. After option expiration, it can drift down or not. This would be a tough situation because you would have to make a determination based on the facts at that time whether or not to exercise your option, depending on whether you think the stock is heading down. If you don’t own the stock, the option to exercise your put may not be available to you if the stock is heavily shorted.

While buying puts with expiration further out does help, it naturally comes with a high cost. There is no easy way around this, the best way is to buy your protection when the stock is at a high so that you are buying protection cheap. If the stock fluctuates up and down with high volatility, the recommendation would be to buy more protection than you need when the stock is high, sell the extra protection for a profit when the stock is low, and repeat. If in the event that the stock goes further down, you have the minimum protection that you need. If the stock goes up, you just make less because of what you paid for the extra protection.

  1. Excellent analysis for this special situation. Fortunately, I haven’t got into this scary scenario, but I’m glad to read it so that I will try to avoid it or know what to do if it would happen to me.

    Many thanks for bringing up!

  2. You’re welcome, I didn’t learn about it until I got into such a situation myself. Hope that yourself and others can learn it at my expense rather than your own.

  3. Very good write up. I was searching for scenarios like this online.

    I just had a similar situation with CHBT. I guess I was happy to lose abit, but able to exercise my ITM Put while its trading halted. Hopefully the guy who sold be his PUT, don’t exercise his, so I’ll be short with a stock, and when it re-trades it gaps down !

  4. Thanks for the info. Currently have a small position in some Sino Forest (TRE) puts. Was wondering the logistics of it, thank you for the rundown.

    I will probably short the underlying next time and buy the calls to get similar exposure as the put next time to avoid this. All and all very interesting.

  5. Thank you for this excellent and detailed analysis!

  7. This is an excellent writeup. It answers a question that I haven’t been able to find a satisfactory answer for some time.

    I have a question though. Will there be a Scenario #3?

    – I’ve bought a put option.
    – The share price collapses because of yet another financial crisis.
    – I want to cash in by closing my position before expiry.
    – But there is no market. Market makers refuse to quote because of the financial meltdown.

    Will this kind of liquidity issue be a real issue?

    My thinking is: when I long stocks, I’m simply owning the underlying business. Even if the stock market closes for years, I’m still the owner, getting the economical benefit of the underlying business. But if I long puts, I’m only holding a contract against a counterparty. Whether the market is open suddenly becomes a primary factor.

    What’s your thought?

    Posted by John (@portfolio14) | March 8, 2013, 12:06 pm
    • Hi John,

      If the stock is not suspended for trading, the options market makers would always be able to give you a quote. This is because they can buy the stock from the market, buy your deep-in-the-money put option, then proceed to exercise the put option.

      So if the exercise price is $20, buying the stock costs $0.10, exercising the option will net $19.90 (ignoring transaction costs). If they quote say $19 to buy your option, they can make the difference. If you don’t think that the price quoted by the options market maker is fair, you can of course do the same (i.e. buy the stock and exercise the option) to monetize your position.

  8. This is a very informative article so thanks for writing it. I own some puts on Suntech so could find myself in this situation soon.

    On a related note, do you know what would happen if you have sold an uncovered call on a stock which is suspended and unborrowable and you get assigned on the call? You have an obligation to deliver the stock but no way of fulfilling it. What will a retail broker do in this circumstance?

    Posted by hoveite | March 14, 2013, 7:42 am
    • Hi Hoveite,

      I suspect that you would still have to deliver the stock if the call is exercised during the suspension period. Typically the OCC will release guidance on the specific situation. If something is not specified by the OCC, it will depend on how your broker decides to handle it.

      Most likely your broker would borrow the stock to meet the exercise, and put a higher amount of margin required on your short position (e.g. say the stock closed at $1 just before suspension, they may set the margin to be $3 to guard against the stock spiking up after the suspension). Either the broker will immediately cover the short when the suspension lifts, or allow you the flexibility to close it later.

      I don’t have an actual experience of getting called on a naked call on a suspended stock, but just my thoughts on how it could play out.
