"Risk Management & Position Sizing

Normalize risk across all instruments so that you can create risk units. This way, every instrument will be the same in terms of the risk that you’ll represent in your portfolio.

Many commodity traders use the 20-Day ATR (Average True Range) in order to calculate the daily dollar-volatility per instrument. Then, they divide that into the percentage of capital that they are willing to lose per trade.

Example:"

Why are shares soaring at this former biotech turned blockchain company?

John O'Rourke is chairman and CEO of Riot Blockchain Inc. of Castle Rock.

Why are shares in a company that used to be a biotech, then turned itself into a blockchain technology company, soaring this week?

Shares in Riot Blockchain Inc. of Castle Rock (Nasdaq: RIOT) soared more than 42 percent in Wednesday trading, and they soared another 47 percent in Friday's abbreviated trading.

Riot Blockchain used to be known as Bioptix Inc., and before that, it was Venaxis Inc., a medical device company.

Now it's Riot Blockchain as of last month. It says it's trying to become a player in the digital currency business and "a strategic investor and operator in the blockchain ecosystem with a particular focus on the Bitcoin and Ethereum blockchains."

Its former CEO Michael Beeghley told Bloomberg last month that it "decided to changes its focus" to "participate in this very exciting industry that’s like the beginning of the internet."

Now John O'Rourke is chairman and CEO of Riot Blockchain (in an announcement buried in this release) and the company's shares are soaring.

On Nov. 14, shares in Riot Blockchain closed at $7.02. In Friday trading, they closed at $23.60, up $7.61, or up 47.59 percent, from Wednesday's close.

In a piece today headlined, "Blockchain Is the Latest Pixie Dust for Stocks," Bloomberg's Camila Russo comments: "A market truism for our time is that whenever a company touches anything related to blockchain -- or claims to -- its stock shoots up, sometimes even before it enters the industry. The latest example? Riot Blockchain."

Bloomberg notes that on Nov. 16, Riot bought a minority stake in audit and accounting firm Verady LLC, following its acquisition of a stake in blockchain-based payments provider Tess Inc. in October.

Earlier this week, the company appointed Frank Bishop to its advisory board. Bishop was formerly the president and CEO of both Invesco Capital Management and Invesco Inc.

____________________________________

Two kinds of practice

The first is quite common. Learn to play the notes as written. Move asymptotically toward perfection. Practice your technique and your process to get yourself ever more skilled at doing it (whatever 'it' is) to spec. This is the practice of grand slalom, of arithmetic, of learning your lines or c++.

The other kind of practice is more valuable but far more rare. This is the practice of failure. Of trying on one point of view after another until you find one that works. Of creating original work that doesn't succeed until it does. Of writing, oration and higher-level math in search of an elusive outcome, even a truth, one that might not even be there.

We become original through practice.

We've seduced ourselves into believing that this sort of breakthrough springs fully formed, as Athena did from Zeus' head. Alas, that's a myth. What always happens (as you can discover by looking at the early work of anyone you admire), is that she practiced her way into it.

"The cost of machines, even sophisticated ones, has fallen significantly in recent years, dropping 40 percent since 2005, according to the Boston Consulting Group. Labor, meanwhile, is getting expensive, as some cities and states pass laws raising the minimum wage."

BIIB Stock Trade Idea, November 22, 2017

The Bet: Sell BIIB Jan 2018 $270 put for $2.40. This is a bullish trade which does not require a rally to profit. Here I have an 85% theoretical chance of success. But I would accrue losses below $267.60.
Selling naked puts carries big risk, especially for a stock as frothy as BIIB. For those who want to mitigate it, they can sell a spread instead.

The Alternate Bet: Sell the BIIB Jan 2018 $275/$270 credit put spread where my risk is limited. Yet if the spread wins, it would deliver 12% in yield.
