Amanda B. Johnson, with help from her mostly off camera partner (my apologies for forgetting his name), made videos that I find unpretentiously pleasant, clear and quick at explaining the limited cryptocurrency topics that they cover. These videos do not cover every topic you probably want to...

I thought I read somewhere that the opposite is true about fill priority, that is, that customer orders have priority over orders of designated market makers. I think the DMM's got more liberal margining, and, just guessing on the rest here, maybe the right to simultaneously post buy and sell...

Thank you for the correction. I apologize for wasting the time of readers of this thread by my not reading the web page I pointed to more carefully, which states, just before the chart I excerpted, "For the purposes of crediting interest on either long settled cash balances or short stock...

The limit looks like US $10k, not $100k, according to https://www.interactivebrokers.com/en/index.php?f=1595 , after clicking to open the section labeled "Interest Paid To You", in the table entitled "Interest Paid to You on Positive (Credit) Cash Balances": Perhaps you are referring to some...

Protective calls are fine for limiting risk if you are not concerned about margin during extreme moves, but I don't know of any brokerage anymore that offers sensible margining in United States ordinary (regulation T) accounts for protective calls on volatility exchange traded equity products...

Experimentally, it appears to me that Interactive Brokers's new volatility exchange traded product margining at least sometimes requires much more margin for a protective call (short underlying + long call) on a long volatility ETP than a long put with the same expiration and strike, even though...

At the outset of this huge post, let me disclaim that I am just winging it here, and that there must be books and other publications that more correctly explain this. I'm not sure what you mean exactly by "the premium remaining in the calls." I would agree that just before the stock goes...

Thanks for asking a question intended to help get to the bottom of this. The arbitrage is in what you could have done the day before (that is, pre-dividend) if the stock price had been the same (yesterday's price = today's price + dividend) and if the call price did not experience a similar...

I don't see anything inconsistent in this explanation with my approximate model of the price using a combination of three options. I have to run now, but, very quickly, skimming this paper, I think the following paper makes mention of what I'm talking about (that early exercise just before...

Beerntrading, it does not make a difference to my preceding post, but just to clarify some things that might be distracting you, the prices I quoted from today were after the stock went ex-dividend, and the reason I used the ask price rather than the midpoint was to point out how there would...

It seems you are confused about the definition of premium for an option. option_premium = option_price - option_intrinsic option_price <= $2.35 (the visible asking price) option_intrinsic = $1.83 ($71.83 stock price - $70 call strike) option_premium <= $2.35 - $1.83 option_premium <= $0.52...

As I write this, 1,200 $70 August 18 calls for HCN are being visibly offered for $2.35 while the stock is trading at $71.83, a premium of $0.52, which is, importantly for this example, less than the recent $0.87 dividend. In reality, stock prices have fluctuated as usual for the past two days...

Just be more explicit, I should add that the reason that I used the term "ordinary dividends" in my previous post is that, for extraordinary dividends, the options usually get adjusted by a memo from Options Clearing Corporation to mostly avoid the effect I described.

The strikes of US equity options are not adjusted for ordinary dividends. If your calls were in the money, you can expect to lose almost as much as if the stock price were simply to drop by $0.87 when the market opens. If your calls were deep enough in the money, you could lose almost $87 per...

Long ago, I had a business that issued similar incentives, and, if I recall correctly, the contract template for it contained such a prohibition.

I expect your contract has a clause explicitly prohibiting hedging your unvested restricted stock. However, I am not a lawyer. So, please do not rely on this as legal advice.

I made a mistake in the script I previously posted, that has the effect of providing historical data only before July 16th, 2017. I had left a numeric unix time code for a time during that date, 1500194366, in the final wget command in that script, instead of "${period2}". Here is a corrected...

I am not any kind of tax expert or other financial advisor, but my layman's understanding is that, for holding a position over multiple years in an taxable United States account, S&P futures contracts have what, in such a case would be a substantial disadvantage: taxation under Internal Revenue...

I am grateful to Dennis Lee for writing updated Yahoo historical data fetching code at https://github.com/dennislwy/YahooFinanceAPI , discussed at https://stackoverflow.com/questions/44030983/yahoo-finance-url-not-working/44050039 . Using his code as a guide, I have written the following shell...

http://www.etf.com/etf-education-center/21025-understanding-net-asset-value.html?nopaging=1 , which I am not claiming is authoratative, just more likely to be right about this than I am, states: "Distinct from an ETF’s official, once-a-day NAV [net asset value] is the intraday or indicative NAV...
