Unintended Consequences of Systematic Covered Call Writing
Patrick Ceresna
Enhancing income and returns through covered call writing has become one of the most common strategies being adopted by investors. Arguably selling calls against shares and ETFs is considered a conservative strategy that almost any Canadian retail investor can access, in and out of their registered accounts. While many...
Options Brief- Week of July 24
Montréal Exchange
Behind every transaction, there is intention, a belief. Investors typically select options strategies with a clear objective in mind based on a predetermined outlook. One of the most popular strategies is the covered call strategy. We have discussed the covered call in depth in previous posts, but here is a quick summary. The...
Demystifying the Black-Scholes formula
Martin Noël
The Black-Scholes formula is an option valuation model developed by two academics, Fischer Black and Myron Scholes, who first described it in a 1973 article. The article appeared in the same year that the Chicago Board Options Exchange (CBOE) was founded, and the model effectively democratized the use of options. Previously,...
Early Exercise of Options
Martin Noël
Holding shares in a company gives the shareholder the following rights:*The right to transfer ownership, *The right to dividends, *Voting rights, and *The right to residual income and assets. What this means is that shareholders are free to sell their shares, take dividends when they are paid, vote at shareholder meetings and...
Call Put Parity: How to Transform Your Positions
Martin Noël
I have been told frequently – and surely so have you – that selling cash-secured puts is a very risky strategy. Haven’t you? The main reason put forward for not using this strategy is that you could be forced to buy the security, even if the company had just gone bankrupt. In this light, the strategy rightly raises fears....
Delta: Assessing Probabilities Based on the Break-even price
Martin Noël
As we saw in an earlier article, delta measures how much an option’s price moves in relation to a change in the price of the underlying asset. Delta is a variable from the Black-Scholes option pricing model, and it is also used in the industry as an approximation of the probability that the option will be in-the-money at...
Purchasing Put Options or Selling Call Options to Protect Oneself? (Third and Last Part)
Martin Noël
In the two previous articles, we compared purchasing put options as a protective strategy with selling covered call options. The first article used options with monthly expirations, and the second article used options expiring after our period of analysis, from April 17, 2015 to January 22, 2016. In both cases, the analysis led...
Add (ONEX)tra upside without putting on extra downside
Christopher Thom
Onex is a stock that has done very well over the long term. Since going public in 1996, the stock has had an annualized total return over 16%. The company places emphasis on managers owning stock and investing alongside shareholders – this is something I like to look for when investing in a company. For an investor who...
The Greeks – Vega
Martin Noël
This week, we will look at another Greek variable, called vega. Vega measures the amount that an option contract’s price changes in response to a change in the volatility of the underlying asset. You will recall that an option’s time value is influenced by the time remaining until expiration and by the implied volatility of...
The Greeks: Theta
Martin Noël
This week, we will look at another Greek variable: theta. Theta measures the change in the price of an option following a change in the time remaining to its expiration. You will recall that an option’s premium has two components: intrinsic value and time value. But since an option that has reached expiration has run out of...
