To adapt the calculator for our needs, instead of estimating win rate and and standard deviation per hour, we will make those daily estimates. So the win rate would represent average profit per day, and the standard deviation would represent a measure of the variability of daily returns.
Let’s say that your account total (bankroll) is $100,000. You are willing to risk 2% of your money in a single day, and 2/3 of your days will fall between losing and making 1% on your capital. You have a modest positive edge that will earn you 10% on your money in a year, which would be $40 per day on average ($40 x 250 trading days = $10,000).
Your risk of ruin in that situation--the risk of losing all your capital--is only .03%….
The lesson to be learned is that risk of ruin jumps astronomically when one’s edge is eroded and when one’s variability of returns expand. This is why it’s imperative for serious traders to cut their risk (reduce the variability of returns) when they sense that they’ve lost their feel for markets. It’s also why it’s imperative for serious traders to risk manage their day to day trading, so that they cap their daily P/L swings relative to the edge they possess.
And the frustrated trader who overtrades when he loses his edge? Risk of ruin, the calculator tells us, jumps to 100%.
In the wake of the Panama Papers being released, the U.S.Treasury announced that it will use existing powers in order to make two rule changes that are intended to stop tax evasion.
First, in a rule which amends the US Bank Secrecy Act, the Treasury said it will require financial institutions to verify the identity of the real people, or "beneficial owners", who control companies opening account...
All eyes were on this morning's employment report for April, which largely disappointed expectations. The equity market was little fazed by the light growth in nonfarm new jobs. The S&P 500 bounced off its rather unremarkable -0.55% intraday low about 90 minutes into the session. It slowly rallied to its 0.35% intraday high as the final hour approached and ended the session just a tad lower with a 0.32% closing gain.
About that jobs report ... is "mediocre" an apt description? Consider: The number of new jobs came in at 160K, well below the mainstream expectation of about 200K. On the other hand, since January 2011, nonfarm payrolls have increased by an average of 0.15% monthly with a high-low range of 0.26% to 0.03%. The April increase was 0....
It has been interesting as of late reading the numerous views espousing the value of “indexing” and lamenting the short-term underperformance of some fund manager. What is more interesting is a large majority of these individuals have only been involved in the markets post-financial crisis. In other words, many of these individuals have never lived through a 2000 or 2008 type financial market event.
It is only during these periods where true investment “metal” is tested as the battlefield becomes a vast wasteland of bodies and failed ideas. Despite strategies that promote the value of long-term investing and the benefits of indexing, it is the realization of “loss” that derails even the most well-intentioned of individuals.
Two years after Newsweek wrote an inaugural article upon returning to print in which it "unmasked" bitcoin creator Satoshi Nakamoto and which turned out be a hoax (the author "found" Nakamoto using a white pages search), earlier this week the world was fixated on the story of another self-professed bitcoin "creator", this time Australian entrepreneuer Craig Wright, who &quo...
Relypsa Inc (NASDAQ: RLYP) shares have plummeted 51 percent year-to-date, under pressure from debt-financing related concerns. Cantor Fitzgerald’s Mara Goldstein reiterated a Buy rating for the company, while reducing the price target from $42 to $41. The analyst believes the 1Q16 results would be “a stabilizing force for the shares.”

Although we try to stay focused on finding and managing promising trade ideas, the comments in the comment section sometimes take a political turn (for access, try PSW — click here!). So today, Jean Luc writes,
The GOP debate last night was just unreal – are these people running to be president of the US or to lead a college fraternity! Comparing tool size? The only guy that looks semi-sane is Kasich. The other guys are just like 3 jackals right now.
And something else – if Trump is the candidate, that little Romney speech yesterday is probably already being made into a commercial. And all these little snippets from the debate will also make some nice ads! If you are a conservative, you have to be scared now.

Last fall there was some discussion on the PSW board regarding setting up a YouCaring donation page for a PSW member, Shadowfax. Since then, we have been looking into ways to help get him additional medical services and to pay down his medical debts. After following those leads, we are ready to move ahead with the YouCaring site. (Link is posted below.) Any help you can give will be greatly appreciated; not only to help aid in his medical bill debt, but to also show what a great community this group is.
