The fund with the lower standard deviation would be more optimal because it is maximizing the return received for the amount of risk acquired. Consider the following graph:.
If, for example, a fund has a beta of 1. On the other hand, a fund with a beta of 2. Investors expecting the market to be bullish may choose funds exhibiting high betas, which increase investors' chances of beating the market. For example, if a fund had a beta of 0. In the simulations I have assumed that Arnold, Bob and Charlie have been putting in the time required to get a high number of trades, which really is what is required in order to make money from betting.
Click to Enlarge. You can play around with the numbers in the spreadsheet here. First off, the starting bankroll has a very large impact on the results. Also, having a high starting bankroll enables a higher avg. Obviously you as a user of Trademate need to make sure that you have the appropriate bankroll to clear our subscription fee and get results that you are satisfied with.

So one month one could be running at 1. When swings occur will have an impact on results.

- Danger of Multiplication.
- Gregs Hologram (Novella)!
- Verdi, Opera, Women (Cambridge Studies in Opera).
Also note how the effects of compounding increase with time, so that even if one is getting in the same number of trades at the same avg. ROI, the results will improve thanks to compounding, and potentially quite dramatically so. Third, if one is able to run at higher average ROIs than 2. Fourth, note that if you can it is ideal to combine trading on the sharps with the softs, because the higher ROI on the softs can really have a huge impact on building the bankroll needed to make a successful transition versus just going straight into the Asian market.
Fifth, to make a living in 1 year one will need to have an even larger starting bankroll or take larger risks. The next year I would keep going.

While I am no expert, before I start slapping numbers onto graphs, I first try to answer the following questions: What insight are we trying to uncover through our visualization? Pretty charts are nice and all but if there is no insight to draw from them then they are nothing more than empty shapes and colors. Is the visual meant to be exploratory or answer a specific question? These two objectives might seem similar but they are not. An exploratory visualization can afford to be more general and contain lots of information — as the objective is to provoke thought and discussion.
It is meant to be stared at, digested gradually, and different people can arrive at different conclusions upon studying one. On the other hand, visualizations meant to answer a specific question need to do exactly that — they are meant to be unambiguous supporters of whatever point you are trying to make. We will focus on exploratory visuals in this post. Picking stocks is a complicated and subjective endeavor. Our aim here is not to tell people what stocks to buy; but rather we hope our visualizations can help them identify and drill down into more specific areas of interest.

The general case, wherein the same result as yours is derived, is discussed in the Wikipedia entry for the Kelly criterion. Thanks Gregor. Wikipedia has it right. Most other sites — even some professionals — got the formula wrong. Miller, I have your book but it is sorely in need of updating.
The latest edition is over 14 years old. I wish you would release a new edition or version because the info is critically outdated. Thank you for your time. I am confused by your article. I am either misunderstanding something, or your article is incorrect.

The point of the Kelly Criterion is, if you know the correct value of the inputs, the output will give you the optimum percentage of your Total funds to invest. See the payoff table near the top of the article. This is typical of several capital markets investments, not so much in Blackjack. If so what does it mean? So yes, you have likely miscalculated at some point in that case. Surely this should improve results.
The problem in the real world is twofold — first that the leverage comes at a profit-eroding daily cost which is hard to factor in to this form of the equation as it does not have a time element. I believe you overlooked what the Kelly Criterion is ultimately meant to represent.
Your wager is your risk.

It seems to me that if you interpret the Kelley Criterion to provide the percentage of bankroll you should risk there is not a need to rework the formula. Your simulations look to be equal to 0. The article brings up a few issues with the Kelly Criterion in the application to markets. Securities markets generally have some minimum wager.
With a large enough portfolio, the effect may be close to having the option of infinitely divisible bets but I think it is an important point to call out. I am only looking to add thoughtful discussion to the article. Your email address will not be published.
