Impact of the reverseâstockâsplit on NAOV options and other derivatives
1. What is happening?
- Reverse split ratio:âŻ1 postâsplit share for every 10 preâsplit shares (10âforâ1).
- Effective time:âŻ4:05âŻp.m.âŻET, MondayâŻAugustâŻ11âŻ2025.
- Security:âŻNanoVibronixâŻ(common stock, $0.001 par value, ticker NAOV).
A reverse split changes the share count and the price per share of the underlying equity. All derivative contracts that reference the underlying stock must be adjusted so that the economic value of the contract remains unchanged.
2. Options contracts (listed on CBOE/OPRA)
What the OCC does | Result for the contract |
---|---|
Strikeâprice adjustment | The original strike is divided by 10 (rounded to the nearest penny). Example: a $0.90 strike becomes $9.00 postâsplit. |
Contract size (number of shares per contract) | The standard â1âŻcontract = 100âŻsharesâ is reduced to 10âŻshares (100âŻpreâsplit shares Ă·âŻ10). Thus each contract now represents 10 postâsplit shares. |
Number of contracts held | The holderâs position size (number of contracts) is unchanged; the exposure per contract is now 10âŻshares instead of 100. |
Option symbol change | The OCC will issue a new OCCâassigned âadjustedâ symbol (e.g., âNAOVâŻ10â1â) that reflects the split. The old symbol will be retired on the effective date. |
Exercise/assignment | Exercise values are calculated on the new 10âshare basis at the adjusted strike. Cashâsettlement values are unchanged (the total dollar amount of the intrinsic value stays the same). |
Expiration dates | All existing expiration dates remain unchanged. The split does not create new expirations. |
Liquidity & marketâmaking | Because each contract now represents fewer shares, marketâmakers may temporarily thin out the bid/ask depth until new quotes are posted. Expect a shortâterm reduction in openâinterest and volume, but the contract will settle to the same economic value. |
Key takeâaway for option traders:
- Your total dollar exposure stays the same, but the strike price* and share multiplier* will be 10Ă higher and 1/10th, respectively.
- Existing positions do not need to be closed or rolled; they will be automatically adjusted by the OCC on the split date.
- If you hold deepâinâtheâmoney or deepâoutâofâtheâmoney options, the new strike may push the option into a different moneyness category (e.g., a $0.80 strike becomes $8.00). Reâevaluate delta, gamma, and impliedâvolatility exposure after the adjustment.
2. Other listed derivatives (e.g., futures, ETFs, ETNs)
Derivative | Anticipated treatment |
---|---|
NanoVibronixârelated futures (if any) | Exchanges will adjust the contract multiplier in the same way as options (100âŻpreâsplit shares â 10âŻpostâsplit shares). The price multiplier will be multiplied by 10. |
ETFs/ETNs that hold NAOV | The fundâs holdings will be converted at the 10âforâ1 ratio, so the fundâs netâasset value (NAV) per share will be unchanged. The ETFâs ticker and share class remain the same; only the underlying share count changes. |
Binary or structured products that reference NAOVâs price | Most providers will either (a) adjust the reference price by the 10Ă factor, or (b) cashâsettle the product on the split date and issue a new series. Investors should review the productâs terms sheet for the exact method. |
3. Practical considerations for NAOV derivative holders
Check your brokerâs platform â Most brokers automatically display the adjusted strike and multiplier on the split date. Verify that the new symbol appears in your account and that the contract specifications (strike, multiplier) are correct.
Tax reporting â Because the economic value of the position does not change, the split itself is not a taxable event. However, the new strike price will be used for future gain/loss calculations, so keep the original trade records.
Margin requirements â Since each contract now covers only 10 shares, the perâcontract margin* may be reduced proportionally. Some clearinghouses will temporarily raise the initial margin* to offset the reduced share count; confirm the new margin levels with your broker.
Liquidity risk â In the first few days after AugustâŻ11, bidâask spreads may widen and order flow may be lower. If you need to close or adjust a position quickly, be prepared for slightly higher transaction costs.
Volatility expectations â Reverse splits often trigger a shortâterm price swing as the market reâprices the stock at a higher nominal level. Implied volatility on NAOV options may rise for the first 1â2 weeks postâsplit, which can affect option premiums and deltaâhedging strategies.
Corporateâaction notices â The OCC will issue an âOptionsâActionâ notice (e.g., âOCCâ2025â08âNAOVâ10â1â) that details the exact adjustments. Review this notice for any special instructions (e.g., cashâsettlement for outâofâtheâmoney options that would otherwise be exercised).
4. Summary
Impact | Details |
---|---|
Strike price | Ă10 (e.g., $0.90 â $9.00). |
Contract size | 100âŻpreâsplit shares â 10âŻpostâsplit shares per contract. |
Number of contracts | No change; exposure per contract is reduced. |
Symbol | New OCCâadjusted symbol will appear; old symbol retired. |
Liquidity/volatility | Possible temporary thin trading, wider spreads, and a modest rise in implied volatility. |
Margin & capital | Adjusted perâcontract margin; confirm with broker. |
Tax | No taxable event from the split itself. |
Other derivatives | Futures, ETFs, ETNs, and structured products will be adjusted similarly (multiplier Ă10, price Ă10) or cashâsettled. |
Bottom line: All NAOVâlinked options and listed derivatives will be automatically adjusted by the OCC (or the relevant exchange) so that the total economic value of each position remains unchanged. Investors do not need to close or roll positions, but they should verify the new strike, multiplier, and symbol on the effective date, monitor shortâterm liquidity and volatility, and update any riskâmanagement or margin calculations accordingly.
